Atomic Heart

thanks for the guide and workaround

just want to add. the progress will read 83% if you only missing the shotgun because not done in with one sitting

@BasedHelix after you've finished the game you can free roam. you need to do this in one sitting (no closing the game from xbox home) follow the workaround guide after you finished the gamd

I'm only missing the Railgun. It won't let me pick the neuromodule which is needed to craft the Railgun

I'm making a video guide on this, but its straight after the long intro cutscene/tour.

probably the shotgun should have own blueprint since it appears to create, but for some reason the blueprint did not exist probably they will fix it

while the axe, you get automatically on start after the car travel, and you can create again if you dismantle

Yeah, the railgun is glitched, specifically when defeating a boss that drops the special module that you need, you can’t pick it up.

I did not have to start a new game to get the shotgun.

I was at the last save point before the twins and i dismantled all my weapons and went through creating them all, ready to start a new game and get the shotgun as the guide says but i got the achievement after creating the dominator.

I have been playing for about 6 hours and have created other wepaons during that time, for example i created the fat boy, died and created again later.

i can’t get any blueprints. all i get is duplicate blueprints. like what went through their head when they went “oh yeah, let’s make it 20x harder for them to get all the blueprints by adding duplicates!!”. it’s so draining man. i’ve opened over 200 chests and i just get duplicate cartridge prints.

@Akhis, that’s because blueprints reset as well after you exit game.

yeah i just went around the map and getting random chests + doing the testing grounds and i just need the railgun now

I'm stuck in the same boat as you Akhis... searching all recommended chests for the railgun only to get another item. Started a new game and got different blueprint spawns but no railgun just yet...

Pretty sure the schematics are based up number of chests opened and not random. E.g. you need to open X amount of chests to unlock the railgun, with the railgun being last. I've found blueprints only unlock within silver chests and not every time you open a silver check but every 2/3 chests open you'll get a schematic and you have to unlock all other schematics before you get the railgun.

This is all speculation obviously on my part. Some people seem to get it so early on though, whatever. If it helps any though I finally got the railgun! It was in a gold chest in the Pavlov Complex. From the start I went all the way down the stairs and followed the linear path to a bathroom.

I keep getting duplicate recipes and I haven’t been able to get new blueprints which sux

Man let me tell you, i’ve opened probably close to 100 chests and i still don’t have this damn rail gun 😡 i’ve checked all the chests in 4 sectors so far and nothing

well, i have officially opened every single chest i could possibly find in all districts + vavilov. i estimated roughly 120 chests were opened and i got nothing. i also made sure i had the shotgun in my inventory so the game wouldn’t think i was missing the blueprint for that (since someone commented that i need all the other blueprints to unlock to get the rail gun) and i just got nothing. completely wasted hours of my life.

good luck trying to even get the one specific material to build the railgun. everytime i kill dewdrop to get it, the material needed will just get stuck in mid air

Well that's a relief to hear. I'll hold off until I hear more about Necromancer as there were a couple of bugged bodies, but glad to hear progress is being made.

Update - so after another 15min I found a chest with Railgun, I didn't have materials to craft all weapons at once, so I crafted only guns, then disassembled and then crafter melee weapons and got the achievement!

I have crafted all of them over time and i not got the achievement do you have to have them all in inventory or is it just another bugged achievement that will wait till patched.

Like what LV Drejz said I also didn’t get credit for a particular weapon until it was in my inventory on my person.

Never got this due to missing railgun, despite opening every chest. Stopped on 91% with shotgun blueprint and railgun blueprint missing.

You need to have all the weapons in your inventory for this to unlock 👍🏻

I have all 12 weapons restarted console,had them all at once in my inventory I tried everything and achievment still not popped tracker says 91 percent

Try moving each one into storage, then back out and into your hands. See if that works.

Is this bugged? I'm sitting at 75%. I've tried crafting both the fat boy and rail gun (newest blueprints) and my progress isn't increasing as I craft them. Tried moving stuff around between inventory/storage, quitting and trying again, etc.

Anyone know how or where to get the railgun blueprint I've found other ones since the patch but still no railgun

Just unlocked Lord of War and 'Unlock all achievements' achievement didn't pop. What a joke!

Got it! It popped at the title screen

Built every weapon, had them all in my inventory but still no achievement.

Guess I will have to do the new game route... Can you start a new game without losing your current game progress?

Same as Mr Spineless, have all the weapons (after the last patch 1 3.5 the neuromodule bug is fixed) and nothing on Lord of War achievement. Have all the 12 weapons at the same time in the inventory and nothing. Tried deleting and recreating one by one and...nothing. Stuck at 91%. And I've never dismantled the shotgun.

I don't think people have notice but you can now craft the shotgun.
Make sure to save your game first before dismantle the shotgun or move shotgun into storage, then go to crafting and see if it let you craft the shotgun.

For those struggling to get the railgun... Pretty sure all of the weapon unlocks are tied to opening RED chests such as those in Vavilov safe rooms (first major area of the game). The red chests after Vavilov are not found in safe rooms anymore and you actually have to go find them in the game world/testing grounds/story levels. You need a certain number of red chests opened to get the railgun, which is why everyone seems to get it at different points in the game. For example, I did a LOT of exploring and got the railgun before even going into VDNH after defeating Hedgie. But tbh the railgun is pretty useless as it stops enemies from dropping loot, and fat boy does crazy damage when upgraded so you can cheese pretty much any enemy. The fat boy ammo is also very plentiful you will never run out.

OK - I’m gonna flag 2 points.

1. The Railgun

It’s not a guaranteed drop EVER in this game. It’s pure RNG based on your current progress, so the more you progress through the game through testing grounds - it’s gonna take longer to appear. On my first playthrough on normal - I did ever ground early - and it never dropped. On my Armageddon playthrough - it dropped in a random box while collecting robot parts to activate drill mode. Any of these videos on YT showing guaranteed spawns is complete BS.

2. The Achievement Itself

IF like me, you started another playthrough to get your missing gun and it’s still not unlocking - I managed to get mine to unlock just now doing this…

Proving you have all the necessary blueprints - you’re going to need to unlock the perks on the character for max inventory space first.

Then create a save wherever you want as long as you’re next to a Nora. Transfer all your inventory items over to storage. Now, one by one transfer your weapons back you already have made. Then, create the missing ones as they will go straight into your inventory and track correctly.

Achievement will pop after you pick up the last gun. Hope this helps

25-Mar: the no shotgun tracking bug workaround doesn’t work anymore.

Ive dissmantled every gun and crafted then again straight into inventory and not storage chanhed them to storage and back and nothing ive crafter the railgun multiple times and nothing im stuck at 83%

I completed the requirements while playing on a downloaded version after the big March patch but progress was stuck at 66% or similar.

I fixed it by uninstalling my installed copy, then hopping on the cloud version and crafting the weapons again. It immediately popped on crafting the 12th weapon again.

I was also stuck at 91%, it unlocked midway while I was crafting all the weapons again.

I just transfer the guns from my storage to my personal inventory and it popped today! Hallelujah!

I didn't need to have all of the weapons in my inventory at once or even own all of them all at once (I dissembled some to generate resources for others). I did this all in one go without quitting or reloading my save, making sure to put them in my inventory at least once before dissembling.

Do they need to be in the inventory in the same time?

You don't have to keep the weapons. You can dismantle them and built the next weapon.

I can't find the railgun blueprint. I got all chirpers/lootyagins/dead people achievements, but not this. I walked for hours scanning the whole map for chests, opening hundreds and never got the blueprint. It seems impossible to go back to the VDNH complex some people seems to mention they got it there (but also believe I opened everything in it). The worst thing is I have a vague souvenir of getting it right at the start of the game, but I think I was overwhelmed by robots and reloaded the checkpoint. Maybe that's what bugged it?

what about the swede and the pm? also whats the mp handgun lol

You can start a new save if you are missing one weapon and it will stack from a previous playthrough so you don't need to do them in all in one playthrough, I somehow missed the Sword from the first area after chasing Victor, so if you know what your missing and where it is you can b-line straight to it

I started the new game, and now you can obtain blueprints normally, even my game was closed and I progressed opening new chests and finding new blueprints. Right now I'm at 91% and I'm still only in the VDNH complex, I'm guessing last one - Railgun will give me trophy even without Shotgun.

What I did just crafted each weapon at NORA, and when I was missing parts I disassembled the one I made and made a new one and progressed. Hope this helps.

Same goes for any other tracking issue achievements, seems like latest fix fixed closing the game and continuing as my Necromancer achievement also tracks properly now.

I have 12 weapons and the tracker stuck at 75% for the love of God...

@thug spencer craft them in one go, if you miss materials for all, disassemble and continue crafting the ones you don't have, make sure that you pick them up so they go in inventory, worked for me after the latest patch with new game

Was stuck on 91%
Did the dissembling as I have all weapons
Cheevo unlocked when I crafted the fox
I kept the shotty in my inventory btw while doing the dissemble and crafting process

i got the railgun blueprint at the top of the exhibition center - there's an electric grid puzzle at the top and the mission tells you to go back to the exhibit (the whale i think) but i continued outside instead and i got the railgun blueprint in a chest up there :) my friend said he also got it there but who knows how accurate that is :) i re-crafted everything (except the shotgun) and i have all 12 weapons and no cheevo 😾 i also didn't get the kill the twins one and the craft all consumables one and i should have those too 😾😾😾

@Buachaill Dona The shotgun blueprint can't be gotten in the current state of the game but 91% means you just need the railgun anyway. After doing 4 playthroughs and reliably getting random blueprints but from the same chests, all I can suggest is grabbing these 5 open world boxes if you’re endgame and still missing any of them. It seems you need to open a set number of ‘blueprint boxes’ before you get rewarded the RAILGUN.

- West side of map, ring with Testing Ground 6. At the boat station, on the dock where you first activated the Hawk to get into Hedgie's arena (Credit to Nesmaster).

- South side of map, ring with Testing Ground 9. Directly north of the words Kollectiv Complex above the road in some polymer mid-air.

- East side of map, ring with Testing Ground 2 & Plant 01. Directly north of Plant 01, near the center of the circle, there's a save house. Walk out of the save house; there's a bus stop in front of you and a lake on the left with a dock. There's a rocky cliff with houses on top in front of you. The house nearest the point of the ricky cliff (not the shed) has a yellow chest on top. Climb some hay bails, jumping to the left, to get on the roof. (Credit to E vee dub)

- Check inside the same house as the one listed above for a normal chest.

- North-east side of map, ring with Testing Ground 11. After leaving the theater behind the exit building. It can be located to the west (about 50 feet) before crossing the bridge over to where you fight Belyash. Directly north of Hawk 01.

You will have to get a lot of mission locked ones also though. I'll put them chronologically. All the red ones in the safe rooms for the first half of the game. Lesnaya Station, on the way in a farmhouse in the wheat fields & on the way somewhere on your right o top of a red house. Facility 3826, in a room before and after you meet NORA, each sector (cold, hot, algae & assembly) seemed to have a chest in their breakrooms too. VDNH Exhibition complex, under the first room turning puzzle (Credit to Lordacris). Pavlov complex, from the start go all the way down the stairs and follow the linear path to a bathroom with a gold chest and a chirper in the toilet next to it. Lighthouse, holds 2 chests that give blueprints. I'm sure there are more but that's all I got from the top of the dome and previous comments. Hope this helps someone.
