    As an obvious tip, take it slow and be on your guard all the time. It is essential that you block, counter, and shoot anything that gets close. If you shoot before blocking and countering an alien most times it will explode into a pool of acid and kill you instantly.

    When you get involved in firefights with many aliens try and backstep toward a corner shooting and aiming carefully...as you reach the corner sprint through the middle of the attacking group slowly picking them off and backstep toward another corner, rinse and repeat.

    Always use turrets to your advantage...lure aliens into its sights to help save ammo...and yourself!

    Also keep a shotgun and scope rifle with you. The scope highlights enemies through walls as well as the invisible predator when you fight it in the arena. Don't waste shotgun secondary attack unless it is against tough enemies - like Preatorians and the Predator.


    Mission 1: The Colony
    Fairly simple mission up to the club. Choose one direction and run around, this part can be done with just the pistol, run, turn, shoot, run again. If it beeps infront of you when you run, just run straight past it, get some distance, turn, shoot. etc. Keep your distance and it shouldnt be a problem.

    After you reactivate the turret with Echo team watch the bottom left vent for a xeno, make quick work and run upstairs, kill the next 3 xenos (you can lure them to the active turret if you want). Run up to the barricade and spray with the assault rifle, after about 30-40 seconds the door behind will open. Follow the marker to the elevator door, (its easy at this part to just block and counter any attacking alien) after another 15-20 seconds the elevator will open.

    In the sewer proceed slowly round the first corner, spawn the xeno, kill it, then proceed round to kill the next xeno that spawns on another corner, and then again a third time. Right after this there is some rifle ammo on the floor. Pick it up and SPRINT to the end, dont turn to shoot anything, hug the right side of the tunnel to avoid 2/3 aliens on the left wall - i made the mistake of hugging the left side, shooting one, and dying from a pool of acid. Sprint to the other side of the small circular blue pillar thingy to end the level.


    Mission 2: The Refinery
    Go through to the alien shadow on the wall, as the alien runs off shoot a round or two at it and an alien will come round the right corner. Take your time round each corner, picking off any xeno you come across. Proceed through the objectives into and out the outbuilding, taking it slow and try to only use the pistol, picking up all ammo and weapons you come across - one xeno lurks in the room with the Pulse rifle, and extra shotgun shells can be found next to a hole on the same floor the elevator stops at on your way out.

    At the bridge reload the shotgun, and have the pistol out ready. As you cross the bridge 6/7 xenos come. Dont forget to use the explosive tanks when xenos group around them. You'll probably still have 5 get across the bridge after pistolling a couple and using the explosives. Shotgun at the ready - WAIT, for them to attack you, block and counter to knock them to ground and then shoot them with a single shot at close range (RT not LT). If you dont wait to block and attack, most times you will shoot them mid attack and spill acid over you. Try and save shotgun ammo and use the Pulse Rifle if some xenos wont die from 2 shotgun shots.

    Continue over the bridge and cautiously through the mine - a face hugger will come out under the large fan. When at the hackable door collect the ammo and quickly run back round the corner to familiarise yourself with the layout as you may have to run backwards shooting the xenos that come at you. When you hack the door the xenos can initially come from either side, once you know where lure them to the canisters and use them, backpeddle round the corners (not into a corner) and unload whatever you like - once again it is possible to just use the pistol but you will need to block and counter effectively. Remember to glance at your beeper as although you can backpeddle away the xenos do use the vents to flank to your side and even behind you.

    Proceed onward, following the markers, through the twisty room killing 3 xenos, another xeno in the corridor after that, down the stairs, and into the hive. You can shoot at the eggs and then face huggers at a distance, or if you want, run right up to one, and just as it opens (i really do mean as it ONLY JUST STARTS to open) use pistol secondary fire twice right on the rim as it opens to kill a facehugger quickly - if there are multiple eggs right next to eachother kill them at distance instead. Dont bother with the flamethrower, just pistol Zandt in the face. Half a dozen xenos will come for you. You can pistol the first one or two, then use the pulse rifle or shotgun. Remember the 'block, counter, shoot on the floor' with the shotgun if they are at close range.

    Up the elevator shoot the xenos on the walls, the eggs in the green mist in the middle can be left alone - if you dont need the health or drop in accidentaly. There are 6 xenos in your way to the marker and 3 more eggs. In the egg filled room take your time killing all the face huggers with the pistol and let them come to you before flicking the switch. If you want to be daring you can flick the switch asap and then grenade launcher the glowing hot pipes to kill all the eggs at once - though a couple of facehuggers might be around to jump on you and end your mission for you.

    When the xenos come they continously respawn so shoot them with the shotgun in the legs to cripple them. If they are crippled and not dead it will prevent more from spawning - they do bleed out though, so pay attention. As soon as the switch is ready again press it to end the mission.


    Mission 3: The Jungle
    Replace the flamethrower with the scoped rifle. You can one shot kill most enemies, particularly because the long heads make headshots way too easy, (particularly for those that play FPS) and for weaker enemies like the acid spitters sometimes a single shot in the leg or body will also put them down for good. Those with surround sound will be able to hear most enemies first, look in the general direction and use the scope zoom to pinpoint them through walls, in trees, and in dark areas. Follow the marker into the cave, where 2 eggs will open, and a 3rd facehugger is by the hack point. Go through the swamp, press the switch, proceed to the marker while killing the xenos that come for you.

    The compound is simple enough, grab a power node from one of the outbuildings - one has a xeno, another a facehugger, and a shotgun in the last one. Don't be caught off guard by a xeno in the main building, upstairs, on the wall just on the left through the door. Sprint outside the main gate watching for the red lasers of the predator.

    Continue throught the jungle where there will be several acid spitters on the way, its easy to sidestep the acid, and even easier to fire the scope rifle from the hip and kill everything before they have chance to spit anything. When you see the big doors at the end use the scope rifle - it will highlight one of the androids on the floor, he will get up if you get too close...aim for his legs and put 2 shots in them to put him down before he even gets up. When you open the door, step forward and fire a random shot, retreat to the corner and peek round it. Aim down the scope and shoot - anywhere between 4-6 body shots can kill them but its easier to save ammo by going for the limbs. One of 3 androids has a rifle himself, and easily kills you in 2 shots, and rarely misses. Hop back round the corner if one or two decide to rush you, use the scope to look through the wall, use the shotgun if they get too close.


    Mission 4: Ruins
    Run forward and replace the pulse rifle with a scope rifle, as you go forward the first beep is a phantom and cant be seen and wont attack you. Listen for the screams of the aliens, use the rifle to find them and put them down. When you hack the door up the stairs 3 xenos will come for you, shotgun them. There are two androids in the next room on the ground floor - use the rifle to find them and take them out. If you run into the middle of the room you will be shot upon from above. Another androis will be up a set of stairs next to an explosive canister, two more are upstairs, one behind a wall on the left through the doorway, and one at the far back infront of you. There is a 3rd inactive on the floor on of the corners. Use the rifle to find the one on the floor.

    In the next area grab the smart gun and burst fire xenos at mid-long distance. You can kill the first wave with the first clip. Watch your left as an acid spitter is on the wall and can be overlooked. Follow the marker, watch the beeps, burst the smart gun. When you get to the dropship itself another few xenos come, again, use the smart gun. When its over, run over to where you dropped your weapons for the smart gun and pick them up again (shotgun/scope rifle).

    The ruins themselves are easy to get through, stick with the rifle, follow the beeps, shotgun anything that gets too close.

    The arena with the predator is fairly simple...use the rifle to follow his invisible cloak and shoot him whenever he is stationary, particularly when you see the red lasers aiming at you. As soon as his shield is down he seems to retreat to the same pillar, shoot whatever you have into him before he regenerates his shield. Eventually when he is down to about 1/4 health he WILL charge you. Get out your old shotgun pal and blast double shot (LT) into him and he'll go down without much fuss.
    Getting to Tequila and following her to the end of the level is easy, just rifle everything with headshots.


    Mission 5: Research Lab
    Scope rifle to see the android on the floor at the start. Follow Tequila, shoot the xeno mauling on a corpse. In the large room two androids will come out at the other side, you will have time to kill one and weaken another before the tram gets in your way. You can play the tram part risky if you want to stand against the back wall looking into the tram as the door opens and emptying your rifle on one or two of the androids. A shotgun android will try flanking to your right if you dont shoot him first, and another will move down to your left next to the pillar. You can hang back over by Tequila if you wish, just wait for them to pop out so you can shoot them. Move into the tram and to the left, take aim and move slowly out, picking off one at a time. When all androids are dead move up and kill the two xenos that spawn.

    Continue following Tequila. Up the elevator and through the first doors an android will reactivate on the floor. Use the scope to once again pick out the culprit and put two shots his legs. Continue through the holding area to your marker and put Tequila in stasis.

    Once you have spoken to Katya pick up the ammo and head to the door. Aim for the android past the barricade, but dont move too far out or a sentry turret will rip you apart. Follow the marker killing xenos and a couple of androids in a room, another android is on a walkway above the same room, but he sometimes gets killed by the xenos. Out the next door a xeno comes through the floor next to the turret on your right. Dont go round th next corner as there is a sniper android on the walkway, use your scope to find him, edge out of cover and take him out. There are two more androids down the corridor, as you move down it two xenos will come out the floor.

    For the next series of rooms and corridors go slowly, hide round corners and use the scope when you hear the beeps. Androids will be waiting to ambush you, and in the first area, when the androids are dead some xenos come along. In the first corridor two androids will reactivate, the front left one has a rifle and can easily kill you if you arent careful. Once again use your own rifle to put rounds in their legs before they get up. Over the walkway there are three androids and one at the end of the next corridor by an elevator. When you hear the elevator activate back up because two androids with shotguns will come out.

    When out the elevator activate the switch, in the next room is a facehugger. Go out the building and follow the walkways, xenos will jump onto the walkways in a couple of places, line up the rifle for easy headshots when they land. Move inside and pick up all ammo available, when you get to the large room a Preatorian will jump in, back up to where you first came in, rifle the three normal xenos and get the shotgun ready. Double shot the Preatorian with a shotgun, you will need to reload it before its dead, so stick behind the pillars and use them for cover. Once its dead follow the marker to the big elevator to end the mission.



    Mission 6: The Pyramid
    The only place i had any real trouble was the last mission because you have to fight through a few dozen aliens...then 8 invisible shotgun weilding androids, and finally Weyland.

    At the first part run to the turret and activate it, (you can pick up the smart gun if you want, but i saved it for harder enemies later - the praetorians and invisible androids) If you dont pick up the smart gun get out a scope rifle and sit in the big doorway you came in, aim down the bridge and you can take out at least 10-15 aliens before too many get past the turret. Switch to the Pulse rifle and start running around in circles, hug the corner of the statues in the first area and then run along the bridge so you can use the turret to your advantage again. As they once again start massing together sprint through and back down the bridge killing anything following too close with the Pulse rifle as you go. Rinse and repeat the process.

    As soon as there are no more aliens run to where there are two health packs by a statue and aim at the edge where an Alien will come up. As this alien comes up there will now be 2 preatorians standing on the bridge. Now pick up the smart gun (if you havent already). If the preatorians arent coming at you, tap the trigger at the one at the front (if you hit both, they will both run at you, if that happens, you might as well start the mission again as they rip you apart before you get to kill one, or if you do, you'll have a long time to wait for the smart gun to reload). Just make sure that the preatorians come one at a time, use the smart gun in bursts at distance then hold the trigger when they are right infront of the turret.

    Before moving over the bridge keep the smart gun and pick up the rest of the smart gun ammo. Should say about 150/250 in the ammo counter. (If you already used it all take the Scope rifle and shotgun for the next part) Continue through to the cutscene with Weyland. As soon as the cutscene ends STEP BACKWARDS, turn around, and sprint off the ledge to the right. Heal yourself because you will get hit anyway. If you dont step backward at that part but try and shoot or step to the side you WILL die. Get out the smart gun, and use it in very short bursts (or the Scope rifle so you can see them when they are invisible). You can kill each android with about 60 bullets from the smart gun, or 4 from the rifle - 2 in each leg. Keep your distance or their shotgun will rip you apart. Once they are dead replace the smart gun with a Pulse Rifle and Shotgun, stock up on ammo and pick up the grenades.

    As you go up the stairs into the next room Weyland will come at you. Fire all 4 grenades at him on your left then run to your right and get the shotgun out. Play ring around the rosies (run around the statue basically so he cant hit you) and shoot him with the shotgun (double or single, doesnt matter) just dont get hit by him! He may run around back to where he was at the start so just be patient and keep popping shots at him. Once he's dead run up to the pad. As the next cut scene ends this part is crucial...either tap secondary fire so your gun hopefully recoils into his face or flick up your aim slightly over his face and press right trigger. If you succeed. WOOHOO, if not you'll have the joy of starting the mission again.

    Hope this helps, and good luck.

    Slam Shot SamI don't think you make enough of the Preatorian fight on Research Lab. Easily the hardest bit of the game for me and I've now died several times on it, wasting ~20 mins each time. I'm going to try jumping the barrier and standing on the lift as someone in the comments suggested, maybe you should switch your method out for that.

    The S bot 9000Been a while since i played this game so for anyone in the same boat: your weapons don’t save in between missions (at least on nightmare) so don’t worry about conserving ammo once you’re in a final segment of a mission.


    EDIT: just beat this and it wasn’t as bad as the ratio suggests. There’s a cheese method for both the praetorian at the end of Mission 5 and the dual praetorians in Mission 6. In mission 5: Knock him on his ass with a grenade launcher and run to the mission end elevator, from there you can pop the praetorian with your rifle and the smaller aliens wont bother you (he does spit acid that can kill you though). For mission 6: Look at A Holy Chainsaw’s solution down below.

    Saft Und KraftSo these videos are great. I have only done the last mission. your video was amazing! I would say the hardest part is just staying alive in the first swarm. then I used a tip I read in another solution and backed up to the lift and let the sentry gun do all the work with me occasionaly shooting my rifle. Now with Bishop I tried about 4 or 5 times and I just couldn't aim worth a damn. So I used another video I found on youtube and I went to the side of the pyramid. from there he will stop further back and once he followed me but only when I came out too far. the second attempt I was able to hit him with all 4 grenade shots from that angle which took off one bar/portion of his health each. 4 bars gone. now I didn't even use the pulse rifle anymore. I switched to Rifle and it can see his position through the rock. So use the zoom function then inch out just far enough to catch the tip of his head. I had no problems with it. 3 full clips and he was dead. each head shot took half a bar off each. he didn't even move!!! I hope this helps out some others. Now to do the other chapters!

    Ok in addition to the excellent walk-through above I have my version with a few different tips that i hope will be of help:

    Mission 1 Colony: As a first level this is quite tough in parts compared to a couple of later ones, go slow (you should be an expert at the mele/block move following up with burst firing the pistol at their legs) The nightclub standoff circle in one direction firing, follow the advise of Cpl Hicks "Short controlled bursts" as it conserves ammo and stops the gun traveling upwards ruining your aim, When you regroup with the other marines and go upstairs leg it back down to preempt the request to go there to activate the computer, at the barricade aim at the ceiling where they climb over concentrate fire here with grenades and pulse rifle fire, leg it to the lift when prompted, in the tunnels hightail it past the aliens if you can just keep running for the level end

    Mission 2 Refinery: Run down the tunnel block and burst fire the two aliens with the pistol, back up from the facehugger i the room and use your flares to spot it easier, seek out the one in the observation room in a similar manner, after activating the dish an alien sometimes appears in the observation room but not always however one will either come through the floor or ceiling in the corridor leading to the lift if you rush past him he may turn up downstairs so best deal with him here. Peek into the room on the left to see if there is an alien behind the right hand bookcase he isn't always, grab the pulse rifle and collect the shotty ammo and stim pack by hole in the floor, an alien ofter breaks through the floor or ceiling here (if the one by the pulse rifle does spawn move back towards the lift if you have to rather than towards the exit because of this one or you will be between them). I employed the "leg it" policy on the bridge, but I first shot the far gas canister backed up and did the second one as the aliens came into range of them, then hot footed it over. This way the aliens were further away from the door there was less chance of them getting in (as they all did if i just ran straight for it and then had to fight them in the tunnel!) keep up the pace once inside, one or two often pop up en route to the hack so I found its better to wait just before the fan with the face hugger just to see if any turned up as if you go straight for the hack they may be right on top of you as the others turn up when you activate it (a headache you don't need!) hit the hack swap to the shotty and retrace your tracks to the fan where its lighter and you can see them coming easier, single shot their legs til they are history, from the lift you can run all the way to the major you do not have to fight the 3 aliens in the generator room and the one that pops up just after as the door shuts behind you when you reach him, burst fire the eggs from a distance before you chat to the wallflower, again i unleashed the shotty into the legs of the 5 aliens that turn up just circle the walkway, then leg it past the eggs in front of the lift. I burst fired the pistol into the alien facing me and the two either side at the top of the slope one at a time to conserve shotgun ammo, you can just run straight to the doorway and the final battle but I needed the health packs in the egg pit, again burst fire at them and finish off any facehuggers that hatch (there is ammo in the room to the left with the 3 eggs and 2 aliens its up to you if its worth the risk for it but as the ammo infinatly respawns in the eggs chamber I would leave it) In the egg chamber burst fire the pulse rifle at the eggs and face huggers from a distance until you can hit the lever (legging it right there is risky) grenade the tanks imediatly and whip out the 12 gauge and again single shot the aliens in the legs leave them crawling to give you breathing space it slows down the spawning aliens (kill one another pops up) I had 3 crawling at one point much more manageable (I made the mistake of going to finish one off when one leaped spraying me just as I heard the message saying the lever was ready!!)

    Mission 3 Jungle: I have nothing really to add for this level as its really quite straightforward pretty much every enemy comes one at a time and the spitters keep their distance, you have the scoped rifle and it's your best friend from here on in, go slow keep an eye on tracker if it pings, zero in and it's headshot time, hang back when you hit the andoids the more distance the better.

    Mission 4 Ruins: Pretty easy at start use scope to highlight the 4 aliens in the caves, the 3 aliens that turn up at the door hack can be sniped from the top or drop down and dealt with the shotgun. Inside scope the 2 androids then from the right hand door edge forward and look up to you left and you can see an android above you just begging to be shut down, one at top of the stairs can be damaged but will retreat to the doorway he is easier to take out with a secondary shotgun fire a couple of times, scope the other one who is either at the end of the walkway or on the left and spot the one on the floor. When you get to the part where you pick up the smartgun grab it and imediatly switch to your pistol so you can run, then high tail it to the crashed dropship (pick up the additional smartgun clip to the left of the slope) keep sprinting to the point where it says await reinforcements turn around and hop over the wall back down to where you started, you may get swiped by an alien as you sprint past but you should make it there ok, swap over to your smartgun turn and face the music, now all the aliens will come at you from the front so burst fire when the are in range (watch out for wasting ammo when they are the wrong side of pillars tho) as you can see them coming they shouldn't get a chance to flank or overwhelm you (keep an eye on motion tracker for acid spitter on left hand side) after this initial wave is over the will come mostly from the right of you some from the far steps others out a hole, finally they seem to come from the front again til you hear the welcome sound of "need any help?" (oh now they show up!) wait til you are sure all aliens have come before you swap your weapons and move to doorway (made that mistake and got tagged), I found this part to be the major hastle on this level the rest was fairly easy (did spend a good 8 hours on this level and really grew to hate it) The walk thru the ruins is simple go slow (you can leg it right to the hack door but you will still face aliens coming at you so its better to make use of your paranoid buddy, stick with him) The predator fight shouldn't be a prob (other than the fact that your heart will be thumping and you will be praying you dont die and have to restart!) If you can get his shield down to one block so that 1 more hit will mean he will either go straight to the pillar to recharge giving you 5 shots (its easy to forget to reload and miss the chance to cause serious damage while you fumble for a clip) of he will rush you so ready both barrels to his ugly mush (I really think this should have been the end of this level!) The walk to Tequila go slow scope ahead and pop the nasties in the head (remember not to rush to her as 1 will drop at the end of the tunnel!) The final gentle stroll to the door and the end of the most frustrating level (yes I found this worse than the refinery for some reason) scope shoot or hipfire the rifle or kneecap with the shotty choice is yours watch out for the gas cannisters and fuel cans as a wayward shot (your heart is gonna be thumping as you are so close to the end!) can send you up in flames and much swearing will be heard.

    Mission 5 Lab: Another fairly straightforward level, when you leave the lift out on to the platform run right behind the forklift truck and snipe at the two androids that come out the lift head to your left you should be able to kill or at least take out a leg each before the tram comes, the two that are riding the rails one will climb up ahead of you so beware and deal with him first, the other hides at the pillar to your left and engages battle with Tequila, pick off the others on the opposite platform from the tram doorway or pop out from behind cover, remember to be ready for the 2 aliens that come from the back right when they are sent packing. For the rest of the level slow and steady is the order of the day take everything one one at a time letting them come to you if you can spotting with the sniper scope, the two aliens that come out the floor will hit the closer vent first then emerge from the further right the left (with the scope you can see them before they stick their heads up). At the room you drop through the broken window to where the egg sack is run to the door then backtrack round to the walkway opposite, from here let the aliens and androids scrap it out, ready the shotgun for the aliens that come in they seem to all follow the same route right hand side of the door way down into the lower floor and up onto the walkway corner, all can be blasted before the get near you, snipe all the androids in the control rooms coming up from a distance, a facehugger is in the final room that leads outside don't get caught out, shotgun the aliens on the catwalks outside they can all be seen from a distance, just before you reach the door back inside one leaps in front of you so move forward slowly and be prepared to back up to give you distance from any acid spay. For the final battle with the big nasty if you jump over the barrier imediatly to your left down to where the yellow forklift truck is you can run round up onto the lift and unleash hell on it, you will get spat at (very rude!) by the praetorian but from across the other side and the regular aliens don't come on and bother you (certainly in the couple of goes at this I needed) and once the doofus even fell of the edge after i had hardly fired half a clip at it

    Mission 6 Pyramid: After the smartgun battle in mission 4 the start of this level is pretty easy seeing as you have the turret as well, turn it on grab the smartgun and all the ammo stand next to turret and burst fire when they are nearing the end of the bridge, again keep and eye on your tracker as a few will try and flank left and right reload in lulls in the carnage, for the androids same as mentioned above turn around and drop off the ledge as soon as you regain control you can climb up over the head on the fallen statue blocking the left hand set of stairs whip out the scope rifle as its target practice time, move to opposite sides to where the androids come from to get maximum distance to blow their legs off, the bit with Bishop is kinda hard to explain but if you run up the first set of stairs and then run to the far left corner there is a small dead end ally between the wall and the staircase, that has the data pad at the top, if you go here (avoiding his shotgun blasts of course!) and wait til he goes up the stairs (he can hit you so watch out and be prepared to heal!) he then, i guess, falls of the edge and gets stuck between the steep slope and a crate at the bottom, edge out of hiding and you should see him running on the spot, clear his line of fire as he's pretty mad and will blast you, unleash whatever you have at his knee that sticks out, 'nades, sniper rounds, pulse rifle til you invalidate his warranty, oh and be quick on the draw to finish him off but you know that part!


    Good luck with this achievement it's a real pain :)
