How to unlock the You Need a Gun achievement in The Callisto Protocol - Definitive Guide

The hand cannon is the cheapest and earliest weapon you can fully upgrade. It'll take 2,800 credits to fully upgrade it. I had enough credits for the last upgrade in the mission Habitat.

I’ve also noticed the a lot of the rare achievements don’t pop with a diamond 💎 They’ve been unlocking like an achievement over 10% which is also strange.

Yes it seems like some of the achievements are bugged a little bit. I'm not sure why this one wouldn't unlock, I bought the last upgrade for the hand cannon and it popped once I exited the reforge machine. I just reverted my last save to get my money back and moved on lol

I’ve cleared the cache and deleted local save and just tried again and it won’t unlock. I’m gonna try uninstalling and reinstalling the game and try again.

Ah I was gonna say did you get the one that branches off to the side. I haven't had to many issues unlocking achievements in this game, just tracking is a little wonky.

Make a save, spend the 2,800 on the pistol, have the achievement pop and reload, then spend on Baton. That's my intention when I get the creds ;)

This one is bugged for me. I fully upgraded most of weapons and no chievo. I started a new campaign (in dismemberment mode) and fully upgraded the hand cannon (the easiest one) and no chievo. Edit: started a new game, normal mode, on easy, play until fully upgraded the hand cannon and finally chievo unlocked.

This one seems incredibly finnicky. Only unlocked for me when I upgraded EVERYTHING (on NG+). It popped alongside Armed to the Teeth.

This achievement isn’t unlocking for me. I’ve tried it twice already. I’ve upgraded the pistol with Boom Bullets and the achievement won’t unlock. Are there glitchy achievements in this game because this definitely looks like one.

In case anyone is wondering, the Stun Baton does count. I quickly realized that most of the combat was going to be melee, so I focused almost all my upgrades on the baton. It takes 11,700 credits to fully upgrade the baton, which I figured was worth it considering it was going to be my primary weapon. It took a long time to get that many credits, I bought the final upgrade halfway through chapter 6.

The easiest weapon to do this with is the BI-55 Hand Cannon. This is for a few reasons: 1) it only has four upgrades, 2) those upgrades are cheaper than all the other weapons too. The alternate fire “TK23 Boom Bullets” upgrade, for instance, is only 1800 credits, while one of the top upgrades for the Stun Baton is 2700.

In terms of the best way to get credits. That’s a case of looting everywhere, and sacrificing inventory slots for loot to sell - which is mainly excess syringes, excess ammo and all kinds of sellable goodies and what not. Upgrading your equipment is the key to making the game that bit easier, so regardless of this achievement, you’ll need to do this throughout the game anyway.

Pistol is the cheapest weapon to upgrade. This is the first ranged weapon, unlocked according to the story in Chapter 3. The cost of fully upgrading is 2800 credits, the last upgrade costs 1800 - it’s best to save before upgrading and after receiving the trophy, reload this save to get the credits back and invest them in more powerful weapons (especially when playing on maximum difficulty).

If your trophy is glitched, try my solution to the problem. We find weapons where the slot to the right or left is not pumped up and it is imperative that the very last one is at the beginning of pumping and not at the end, we pump up the weapons from the top of the column to the end without touching the squares on the right and left, now we pump up the right or left one, it worked on two consoles !

I tried the option with “side” pumping according to the advice here, but it didn’t help. This is what helped: you don’t need to delete or reinstall anything, just close the game -> disconnect the console from the Internet (just in the settings, no need to touch the cable/modem) -> open the game -> load autosave before leveling up to the maximum -> buy the final weapon upgrade -> we record the receipt of the trophy.

The trophy only dropped when I upgraded all available weapons in the game.

Who has a bug with the trophy? Helped: deleting the game, deleting saves from the PC, installing the game, turning off the Internet, passing to the end of the second chapter and pumping the pistol to the maximum

I accumulated enough credits and, by loading saves one by one, pumped up each improvement cell one at a time (i.e., went to the printer, spent all the credits, returned to the CT with a reserve of credits, pumped up the next improvements), the trophy fell out.

To complete most of the game it will be enough for single mobs.
The last upgrade kills a mob with one shot, but at the same time wastes 5 ammo out of 10 (difficulty “Maximum security level”)

I upgraded my baton and pistol, but the trophy did not fall out. The hint above helped, delete saves, reinstall the game, without internet, a trophy dropped in front of the isolation ward

The trophy for one weapon does not drop out if you play in extreme mode. I switched to a regular game, and after upgrading the weapon, the trophy immediately dropped out.

Upgrading a power glove also unlocks a trophy.
By the way, I recommend pumping it up to the maximum, since it is the most useful, fastest, safest and free way to eliminate and control any enemies except bosses: throw them outside the level, onto spikes, onto turbines, or, in extreme cases, just away Push.

The trophy is really glitchy. It is very advisable not to upgrade the gun completely, but to leave it in case the trophy does not appear on another weapon video. It didn’t fall out on my baton, I reloaded the save 5 times - it was useless. It immediately fell out on the pistol

The easiest way to do this is with the BI-55 hand cannon. There are several reasons for this: 1) it only has four modifications, 2) these modifications are cheaper than any other weapon. For example, an additional upgrade for shooting “TK23 shooting bullets” costs only 1800 credits, while one of the best upgrades for the stun baton costs 2700.

In terms of the best way to obtain loans. This is a case of looting everywhere and sacrificing inventory space for loot to sell - mostly extra syringes, ammo, and all sorts of goods that may or may not be sold. Upgrading your gear is the key to making the game a little easier, so regardless of this trophy, you'll still have to do this throughout the game

The trophy is buggy, it does not fall as a condition, but it is done in such a way that you need to improve all the weapons in the game, but you do not have to complete two games, and in the case of weapons, it may take three passages to improve everything. In my case, on the second playthrough, the end of the colony, there was the necessary amount to improve each weapon in turn in one session, by loading a control point in front of the printer, I tried it in two versions and no matter which weapon will be improved last, you do this manipulation, and the trophy falls .

Obviously a bug in the game due to difficulty (v 1.027), but I did it VERY EASILY: I just saved up the last one cell of 1800 credits to upgrade the gun, paused the game, set the difficulty to MEDIUM, upgraded the gun to the maximum - the trophy fell out. I set the difficulty back to maximum security and reloaded the checkpoint. I was still nearby near this machine (shop) and it only took me 1 minute.
