- "Experimental energy-based handgun that blasts victims into a cloud of mist."
- — In-game description.
The Eraser can be obtained in the armory room aboard the Icarius in Operation Deep Execute. Once scanned, it can be used as a secondary heavy weapon in the player's loadout. When a C6 dies from this weapon, it will explode to pieces.
Unlike the multiplayer version, the Eraser has a built-in Fusion Mag, allowing it to regenerate ammo when stowed or not in use.
The Eraser is unlocked for use at level 15 for the FTL combat rig. It features an integrated Reflex Sight with a custom cyan Distance Triangle reticle. It has a very small hip spread allowing for high accuracy and a fast fire rate for quickly taking down groups of enemies.It can be very effective for any range as the weapon has very clear sight, allowing the user to target foes from far distances. The Eraser carries two pertinent downsides, faltering in magazine size and payload charge time, rendering the Eraser a weapon to be utilized sparingly, or in need of assistance for a team advancement.
