Completed this achievement solo without any issues at all.
If you are max bureau rank the damage bonus is plentiful in custom games, don't worry about the scaremongering of others saying it's only feasible in Public match.
Loadout to use:Freefire with - Lucky Crit, Marksmanship & MKII.
9mm SAP
Sticky grenades
Take max ammo & full meter consumables as a failsafe to re-fill Jack-in-a-boxes and your special meter if you get into a sticky situation, you do not NEED these, but they give you some breathing room.
Chapter 1, into the storm:Wave 1 - grab a starter weapon wallbuy and head to the first Ubersprengen battery ensuring you charge it. You should fill your special meter here but DO NOT use it.
Wave 2 - head into the main area and train zombies, nothing special here. During/after the wave spam buy starter weapon wallbuys until you get Jack in a boxes and preferably the SVT as a second weapon alongside your 9mm SAP.
Wave 3 - depending on which challenge you get, you can do various things here.
- If you get the repair 3 stations great, just throw a jack down for each one and repair them.
- If you get the Meistermeuchlers, you can either dispatch of them by training and popping them with the SVT, or you can pop your freefire and use the 9mm SAP to quickly dispatch of them.
-If you get the kill X amount of special zombies (bombers or sizzlers), you will want to use your Jacks & special sparingly whilst trying to stay alive, the bombers are definitely easier here.
Wave 4 - time to breathe... grab yourself the armour and max ammo from the supply crate, if you dont have your SVT yet, check for this as well. Head down into the cellar area and charge the 2nd Ubersprengen battery, then get back out into the main area. You simply need to train the zombies around and clear this wave, nothing special, aim for headshots and be aware of your surrounding for bombers spawning.
Wave 5 - Same as above, you simply need to train the zombies around and clear this wave, nothing special, aim for headshots and be aware of your surrounding for bombers spawning - though this time there will be Wustlings, so try keep a wide berth of these guys to preserve your armour. Again, do not use your Jacks/special meter, we want to keep these for the objective waves.
Wave 6 - fun fun fun, objective again. If you get one of the objectives listed in Wave 3, follow the same tactic. Here are the other challenges you can get here;
- Kill the V.I.Z. before it reaches its destination, real simple, pop your special and you will destroy these guys with your upgraded weapons. Throw Jacks between kills to stop zombies crowding you.
- Defend the supplies until resupply arrives, harder than it seems, but in solo its actually fairly simple as the timer is shorter. Run to the OPPOSITE side of the map to where the defence is, sounds counter intuitive but it works. Wait until the meter starts ticking down as the zombies are hitting it, then throw down a Jack near where you are. This will then lure all the zombies across the map to your location away from the supplies. After each jack detonates allow the zombies to run off a little then throw another down. Rinse and repeat until you run out of Jacks. By this point you should be mostly through the timer. If you need to, run back to the supplies and pop your special to dispatch of crowding zombinos.
- Destroy the 4 weak points of the Zeppelin - Real straightforward if you have the SVT. Just wait until the zeppelin opens up its battery points, then pop your freefire, you will kill each one in a couple shots.
- Escort the Bomber to its destination - probably the toughest one in solo, but you can use a similar tactic to the "defend the supplies" challenge. Abuse your jacks to lure zombies as far away as possible. This may not be enough as the bomber is fairly slow moving, so if needs be pop your special and dispatch of zombies. Worst case, you can use your consumables to get your Jacks topped up or special topped up.
Wave 7 - you're almost through! Grab your free armour and max ammos from the supply drop again. Charge up the 3rd Ubersprengen battery by training zombies around it, grenades work a charm here to charge it fast once you've got a crowd. You should easily have the points to upgrade both of your guns, but don't risk it mid-wave, so train the zombies and kill them with the SVT. Not too difficult as long as you're patient.
As the wave ends, quickly run and upgrade both of your guns. This will make the last few waves a cakewalk.
Wave 8 - Standard training, abuse the 9mm SAP here as the upgraded version is an absolute beast. You want to come out of this wave with your 3 jacks & full special in tact.
Wave 9 - Final challenge wave! Will be one of the waves mentioned above. If you can make it out of this wave with your special in tact you've got a free pass. If not, don't panic - this boss isn't too tricky. After completing the wave, make sure to fill your armour and ammo with the supply drop.
Wave 10 - Boss time. There are 2 methods here.
- If you have full special meter, wait for the boss to spawn, throw a jack in the bomb circle, after a few seconds throw a second Jack down. The bomb should strike around now, pop your special with the SVT and unload into his face, he should drop in 1-2 seconds.
-If you don't have full special, stick with the 9mm SAP. Train around the bomb drop circle, and throw a Jack right before it drops. After his shield is down spray him with the 9mm SAP, aiming for the head. Rinse and repeat 2-3 times and he should be dead.
Chapter 2, across the depthsProbably the trickiest of the 3 maps, but still nothing too challenging.
Wave 1 - grab a starter weapon wallbuy and head to the first Ubersprengen battery ensuring you charge it. You should fill your special meter here but DO NOT use it.
Wave 2 - head into wherever you are comfortable training zombies, I personally train around the central area, there is an obstacle in the middle which is easier enough to move around, kill anything in front of you. During/after the wave spam buy starter weapon wallbuys until you get Jack in a boxes and preferably the SVT as a second weapon alongside your 9mm SAP.
Wave 3 - Objectives again... you may get any of the same challenges as Chapter 1 Wave 3, so adopt the same strategies and you shouldn't have too much difficulty.
Wave 4 - time to breathe... again! Grab yourself the armour and max ammo from the supply crate, if you dont have your SVT yet, check for this as well. Head down into the boat area where the melee perk is and charge the 2nd Ubersprengen battery, then get back out into your preferred training area. You simply need to train the zombies around and clear this wave, nothing special, aim for headshots and be aware of your surrounding for bombers spawning.
Wave 5 - Same as above, you simply need to train the zombies around and clear this wave, nothing special, aim for headshots and be aware of your surrounding for bombers spawning - though this time there will be Wustlings, so try keep a wide berth of these guys to preserve your armour. Again, do not use your Jacks/special meter, we want to keep these for the objective waves.
Wave 6 - Another objective wave. If you get one of the objectives listed in Wave 3, follow the same tactic. Some of the same challenges repeat from Chapter 1 Wave 6/9 so use the same tactics here, however there are 2 new objectives that can crop up here. Here are the other challenges you can get here;
- Defuse planted bombs around the ship - This is particularly tough in solo, train your zombies up, and wait until the bomb defuse kit spawns in. Grab it, and buck it for the defuse point. Throw a jack and quickly defuse the bomb. Rinse and repeat. The difficulty here is that whilst holding the bomb you cannot defend yourself. So do your best to stay out the way of the zombies and you should be okay.
- Kill 'teleporting' zombies while in geistkraft vision with increased FOV. For this one the screen will pop up saying something cryptic like "Something feels odd". Your screen will go weird, but that's about it. Zombies will lapse in and out of vision, so just do your best to spam them with the SVT and treat it as a normal round.
Wave 7 - you're almost through again! Grab your free armour and max ammos from the supply drop again. Charge up the 3rd Ubersprengen battery by training zombies around it, grenades work a charm here to charge it fast once you've got a crowd. You should easily have the points to upgrade both of your guns, but don't risk it mid-wave, so train the zombies and kill them with the SVT. Not too difficult as long as you're patient.
As the wave ends, quickly run and upgrade both of your guns. This will make the last few waves a cakewalk.
Wave 8 - Standard training, abuse the 9mm SAP here as the upgraded version is an absolute beast. You want to come out of this wave with your 3 jacks & full special in tact.
Wave 9 - Final objective wave, refer to previous waves for strategy.
Refill your armour and ammo from the supply drop and stand right where you spawn into the map.
Wave 10 - Stadtjager boss! He will spawn right where you spawn. If you have your special, great. Throw down a jack, freefire and blow him to smithereens with your SVT, aiming for the head.
If you don't have your special you're in for a drawn out fight, but not too difficult as long as you're patient. Use your jacks to your advantage to get as much damage into the boss as soon as you can. If he is still alive at this point, you will want to start moving around with your 9mm SAP out shooting anything in front of you to clear a path. Once your confident all enemies are behind you, you will want to turn and take pop shots at the boss whenever you feel it is safe to do so. Feel free to use consumables to refill ammo for more jacks or special meter to make this easier on yourself.
Congrats, that's 2/3 maps done! And really the harder portion is done, as with Chapter 3 you can abuse the Easter egg to make this easier on yourself.
Chapter 3, Beneath the IceThis chapter I will not go into too much depth. As its mostly more of the same for the waves and you should have a good idea of what you're doing by now.
General tips for this map, are to stay out of the middle area when there are lots of zombies still alive. Train in a big loop around the map to keep yourself alive.
To make this easier on yourself, you will want to do the Easter egg on this map, which awards an achievement in itself. Completing the egg awards you with all perks. But it will still count for this achievement as well as your never "Purchased" the perks.
Follow the guides listed here for more detail on the easter egg.
There are some great guides for killing the Goliath boss solo also, thanks to this achievement.
Best of luck, I actually had more fun than I was expecting getting this one and it didn't take me nearly as long as I thought it might.
