End of Abyss All Weapon Locations
This guide will show you where to find every weapon in End of Abyss.
There are 6 weapons in total, and the following trophies are tied to them:
Fallen Crew for finding the Support Gun.
Overload for finding and upgrading the Particle Disruptor.
Power Up for upgrading any weapon to max level.
Super Power for upgrading all weapons to max level. For the materials, check out our All Weapon Upgrade Materials Guide.
None of them are missable, and they can all be found after finishing the main story.
Pulse Gun Unmissable, since you start the game with this weapon.
Riot Breaker Habitation Sector > F1. From the corridor near Security on the left side of the area, jump through the open window on your right to find the weapon in plain sight in the next room. You will pass through this room close to the start of the game to open the shutter leading to the first Fast Travel Shuttle.
Security Rifle Factory East > F2. Enter the small room off the larger room close to the Factory East Fast Travel Shuttle (this requires the Factory Keycard, which you get automatically in this same area during the main story). Then place an Explosive Charge on the left wall (Explosive Charges are also a story-related tool needed to progress) to blow a hole in it, allowing you to enter the next room, where the weapon is found.
Support Gun Outer Sector > B2. The Support Gun is an optional weapon found in the Outer Sector, the first area of the game. However, to get it, you must return after progressing the story up to the point where you reach the Lower Levels.
Getting back there isn't as simple as backtracking along the path you took at the start of the game. The lift won't be operational, so you will have to use an alternative route.
To do this, head to Maintenance > F2 and use an Explosive Charge on the floor just outside the safe room. This will blast a hole that you can jump down. From the room below, head left and continue along this path until you reach the Outer Sector's Shuttle, with the Outer Sector itself just past it.
Now that you are back in the Outer Sector where the game began, head through the now open door in the top right of F1. Inside, head down the ladder, use an Explosive Charge to open a hole in the ground and jump down. You will then be ambushed by a large group of enemies. Defeat them and pick up the Support Gun from the corpse.
Incinerator Lower Levels > F1. Story-related. You will find it on the main path as you go through the right side of the Lower Levels area (the final area of the game), and you need to pick it up to progress.
Particle Disruptor Infirmary > B1. The Particle Disruptor is an optional weapon found at the end of the Infirmary, an optional late-game area. To get there, you must first get the Infirmary Key from the Lower Levels area (the final area of the game). You can find it by burning the Parasitic Spire in the right side labs on F1 (you will need the Incinerator, a story-related weapon obtained in this same area).
Once you have the key, use it to access the lift to the right of the Fast Travel Shuttle in the Habitation Sector to get to the Infirmary. This is a fairly short area, and the weapon is found just after the boss at the end. To reach it, first grab the Restricted Access Keycard from the small room on F1. Then use it to get to B1 (through the door at the top of the right side corridor). You will then find the boss on the right side of this floor.
After the boss, continue north and burn down the wall in the top right corner to find the weapon in the small room on the other side.
