    The description of the achievement is somewhat misleading, you can only earn this achievement by playing Ironman Classic or Ironman Impossible. You do not get this achievement by finishing on vanilla Impossible.

    Ironman mode means you only get 1 save slot. The game automatically overwrites your file. Anything you do is supposedly permanent. However, this can be circumvented by keeping a copy of your ironman save file on a memory stick or on cloud storage. Moreover, you can dashboard during your turn or the alien's turn to revert to the beginning of your turn.
    Eg;
    1) your turn starts
    2) you move your guys. You end your turn
    3) alien's turn starts, he kills your favorite guy.
    4) dashboard before the alien's turn ends
    5) when you reload the game, you'll start back at step 1)

    Thief44's tip- you can sign out of live instead of dashboarding in step 4). This makes the process faster.

    You can probably win this achievement without dashboarding, but it does make it easier. Moreover, this game has glitches. For example, the last mission has a series of locked doors that are unlocked only if you've killed all the aliens in the current room. I had one game where the aliens never spawned and I was glitched. Thankfully I had a previous save.

    I did this achievement on Classic Ironman and it was quite easy compared to vanilla Impossible; however, I personally think Impossible Ironman is undo-able. If you've somehow finished Ironman Impossible, then you are a XCom God.

    If you've read my guide for vanilla Impossible, I basically followed the same script for this Ironman playthrough, although there are some key differences which I've noted below.

    -------------------------------------------

    Money-wise, the difficulty is similar to Impossible in that you are always broke! But here's a trick to get rich quick. Pick the tutorial option in Classic Ironman, pick North America and you will start rich. Starting with the tutorial makes this achievement a joke.

    You should end the first month with around 800$, research skeleton armor and outfit your guys ASAP to make this run a breeze. Then skip to plasma and ghost armor to destroy everything.

    ------Ironman Battle Strategy-------------

    To survive in Ironman, you must play cautiously.
    Most important tip: ALWAYS KEEP YOUR GUYS OUT OF SIGHT.

    Here's how I killed the maps without getting shot once. Using this strat, I rarely had to resort to dashboard. My squad usually has at least 2 heavies (with shredder rockets) and 2 snipers (squadview). Support is useless, I only use the support class to stun aliens due to their +3 movement.
    1) First, keep your entire squad safely hidden, and build a nice kill zone that everyone can shoot at. Usually someplace that you can funnel enemies into.
    2) Now we use someone to scout (I recommend you get 1 assault with lightning reflex). Use the scout's first turn to scout to the edge of his movement range, then switch to your snipers and kill everything that your scout found.
    3) Now use your scout's second turn to return to his safe hiding spot with the rest of your group.
    4) Put any unused members on watch (you will be spamming Y a lot).
    5) If your snipers didn't kill all the aliens, the aliens will try to chase down your scout... and directly into your well placed killzone that you constructed in step 1. If there are too many enemies or if they are behind cover, use your heavies' rockets. Sometimes the aliens take 2-3 turns before they chase you down. Just spam Y (to put your units on overwatch).
    6) once you've killed everything and you feel safe enough to move on, have your scout find a new killzone, and move your squad to your new killzone while your snipers keep watch. Always have your snipers move last, and never move your squad from your nice safe killzone if your snipers have used up their turn. And of course, dashboard if you've screwed up.

    I have to warn you that the game is kinda glitch and will sometimes spawn enemies directly on to your group. Once a muton spawned right behind my sniper and killed my guy in 1 shot.

    Good luck or get the dashboard button ready!

    You still get this achievement after changing the difficulty to Easy.

    Start the game on Classic Ironman difficulty. After the first mission, set the difficulty to Easy and hire 6 new soldiers. When those soldiers arrive they will have 6HP. Playing on Easy also means you will get more monthly income. A month before you start the last mission, set the difficulty back to Classic and complete at least one mission on Classic before you finish the game to get this achievement. I found the difficulty reverted back to Classic for the Alien Base Assault, so I carried on from there on Classic.

    You will get these other achievements at the same time (if you hadn't already got them)

    In January 2013 the Second Wave title update was released. It will download automatically the first time you play while connected to Xbox Live. This makes the game a bit easier.

    From the Main Menu select Single Player then press cn_Y for Second Wave. Select the following:
    • New Economy
    Press cn_B to return to the Select Difficulty menu, then select Ironman, then select Classic and press cn_A. At the Base Location screen select Africa.

    The key to having an easy time of XCOM, is getting money as fast as possible by building Satellite Uplinks and Satellites as quickly as possible. Your next 2 Satellites should go to South America, for instant Autopsies and Interrogations. Other solutions written before Second Wave was released will recommend starting in North America as the United States gives the most credits per month. New Economy randomizes the credits, and starting with 1 Satellite in Africa gives you +30% credits.

    You only have a single game save slot when Ironman is enabled. However, I plugged two USB sticks into my Xbox 360. After every mission that went well, I would copy the save to a USB stick, and alternate between them. If a mission didn't go so well, I could copy the most recent USB save over the save on the hard drive and try again. The second save was just in case something came up that I couldn't handle when I scanned for activity.

    Take the tips up above, as they were my reference. Below are additional tips for my Ironman mode run through.

    -My 6 squads were sniper, 2x Heavies with double grenade and Rocket (One anti robot), 2 support, one medic one sentinel, one assualt with shottie (yes over the plasma rifle, Crit damge on shottie is deadly, my assault had the 2nd most kills and was close to my double tap sniper).
    -I went with tutorial in North America, the tutorial will get you a veteran sooner than a non-tutorial, not to mention non-tutorial you have 4 guys that may die the 1st mission, whereas the tutorial gives you one and a few missions before the actual non-tutorial mission. The tutorial also give you a 2nd satellite for free, non-tutorial you have to pay for it.
    -I had the DLC, it is nice by doing the first mission you get the dlc character, and that gave me my two heavies for the game (one tutorial, one dlc). the DLC character I think has one more hit point and a little better accuracy, so that is nice.
    -Having the DLC makes the council give you the missions (I did the 1st mission only then rejected the next one), rejecting it until you are powerful enough does not increase panic or count against you, so it may frequently pop up, but it can save you one or two extra missions over a couple of months until you are ready. So I didn't do one escort mission after the DLC mission.
    -make no mistake the 2nd DLC missions taken early can be a death trap, regardless of Igor's above post.
    -I didn't build a laboratory or a workshop. two power plants, one steam plant, one Elerium generator should suffice for power. I had two satellite nexus and two uplinks in a square, i.e. 2 1st level, 2 2nd floor. The Foundry came later, essential for unlimited alien nades, ammo conservation, improved med kits, pistol perks. Negative on any Shiv items.
    -Research the items that matter, just because something is 4 days, and something is 10, shouldn't dictate your selection. I wanted the titan armor as soon as possible, instead of doing autopsy which only a few add value, I would go for the meat and potatoes research.
    -Stage your satellites and always have one to launch. A few times I had a 5 bar panic country ready to leave and I would coo them with a satellite launch. Even though that country might have only contributed 50 dollars, it was worth it considering the "All in Bonus"
    -The All in Bonus is one of your first country bonuses to focus on. However do not risk losing other countries to obtain it.
    -Balance spending in key areas, some of the OTS perks are helpful, however aside from the squad size and recovery time, the others are fluff on a low budget.
    -I used the same 6 people, the quicker they level the better killers they become, I had no interest in balancing and rotating. If someone takes damage, swing him out from the front. The reason you want better armor is unless the damage exceeds the armor they don't need to recover.
    -In the beginning I disregarded the grenade and got nano-fabric (+2 HP) for everyone, it was the only way for them to survive a shot from sectoids.
    -When you have the option of abductions, go for Engineers or money (after considering panic levels). Engineers reduce the money spent on items you buy, and at some point some things are locked until you exceed the number of engineers. After I was set for engineers I would take the money if feasible.

    -When you reach the point in the story for the Hyperwave beacon, do not build it, continue playing and doing research. It took about 6 months before they introduced the Sectopod, but by then I had Titan Armor and Plasma weapons. I eventually built the Psi Lab, sent one soldier, and had that ready. When I did build the Hyperwave, it was less than a month until it found the ship, cleared it, built the next facility, had the armor researched and purchased. So it was a quick clean finish.
    -On typical combat keep your team close, yes the nades are annoying but actually when a nade hits it does 5 damage to both members. When they shoot at you it can be 6+ damage easy, which means it might be R&R time for your soldier. If your team is too far spread apart you will falter on defense. Often times when I did spot a group, through various tactics I could clean them up before they even had a turn to attack. In my game I killed 371 aliens, 186 of which were terminated in one shot.
    -Consider attacking with the sniper first, if there are too many, consider attacking with heavies and support, then sniper and assault last (namely because of run and gun).
    -Heavies with the double fire skill help, they might miss once, but when you are about the 50% chance to hit, sometimes that 2nd shot helps.
    -Use explosives liberally, taking out a wall may lose you a turn of attack, but it can open a window for a sniper bullet or team attack. On a couple tough missions rocketing the wall helped turn CQC to long range firing.
    -Know about how many enemies you are up against, it helps you manage your team and tactics. If I know its 23 enemies and I am fighting floaters, I may not want to use a nade when there may be 20 other guys more deserving.

    When someone does die or you make a grave tactical error do use the dashboard method. Every now and then I would fire a rocket and it would go wide left, that can be the difference between cleaning house or carrying corpses. Purchase a memory stick, and copy your game, you never know when you may not recover from a mistake.

    I want to add one tip which helped me significantly to great other solutions. Used this with great result for Impossible & Classic+Iron.

    If you play with Slingshot DLC from beginning game on Impossible/Classic+Iron will be easier because you will get tons of great loot (especially from last mission, sell 1/3-1/2 of it and keep rest) you can sell and possibility to capture Muton quite early in the game if you build alien interrogation chamber no later than at end of 1st-2nd week of second month and research teaser weapon (all which will speed up plasma weapons research).

    On Impossible I started from Africa (and my first priority for full sat. cover were Africa and South America for faster research of better weapons). On Ironman started from Asia.

    Missions from DLC are randomly received instead of normal side missions so you can level up faster. There are total of 4 missions, all which you should receive durring firsr 1,5 month of game (or from time you installed DLC).

    Mission 1. Friends in Low Places
    Escort target, keep save from before mission and rotate maps until you will get cemetary one, it's easiest IMO.

    Enemies: About 10xThin Man and 1/2 Muton on Impossible playthrough, on Classic 1xChrysalid, about 5 x Thin Man and 5 x Sectoid.

    From start tako cover and kill intial wave of enemies (set everyone to guard) then go through lower right corner to upper right of map and you don't need to fight with more then 2-3 enemies at once. Be sure to have soldier with shotgun, from close he can take down Thin Man one shot.
    Reward: $200, 2 Engineers: 2 Scientists, Heavy class soldier recruit (Lieutant!)

    Mission 2. Confounding Light

    Enemies: (Impossible) - 10+ Thin Man, about 4-6 Mutons. But you can skip mutons who spawn begind if you are fast enough
    (I got it around end of 2nd week durring 2nd month of game (12-13th April)

    This is quite tough mission. You have 10 turns to reach 5 checkpoints and blaze through lot of Thin Man and Mutons (the latter spawn when you hit given checkpoints).

    I finished mission with 2 Assault (shotgun), 2 Heavy (I gave all my heavies SCOPE for whole game), Sniper and Support. It's also good if you already developed laser pistols and rifles. My Support had Laser Rifle, pistol and another pistol for Sniper)
    Reward: 2 engineers.

    Mission 3. Gangplank

    Received it few days after previous mission, 2-3 days before first Terror mission from main game so keep your best soldiers healthy or buy 50% faster injury healing. You can also do Terror mision first.

    Assaulting Battleship but much easier than normal 'UFO crash site/landing' missions. Just clear one objective at a time.

    Enemies: (Impossible) Cyberdisc, Chryssalid, Muton, Sectoid, Thin Man

    Reward: 2 engineers, 2 scientis and about 6 of each UFO items (flight computers, power cores ) so ealier you can sell 2+1 you already have from one of ealier Ufo crash missions if you need cash.
    Fusion Lance research + launcher
    About 300 Elyrium
    About 500 Alien alloys
    About 70-80 weapon fragments

    The four people who posted before me already laid out some solid guidelines for getting this cheevo, so let me make this really easy for you. You already have to do five play-throughs for the "A Continental Fellow" cheeve. And if you're going for this one, then you're obviously going for "Our Finest Hour" too. Make your Impossible difficulty your fourth, penultimate run. After winning on Impossible, a Classic Ironman run will feel like a day at the park. Past that, there are really only two absolutely crucial pieces of info you need before starting:

    1) You have plenty of time to exit to the dashboard if things don't go your way during a turn, so don't sweat it.
    2) Make a backup copy of your save before starting the final mission. If that glitch where the aliens don't show up to unlock the doors happens to you, you're gonna be one very unhappy cheevo hunter.
