In the game Mutant Year Zero: Road to Eden you get a lot of loot and some of the items found are useless for the team. On this tutorial page, we inform you if the game allows you to sell your items.
Unfortunately, Mutant Year Zero does not offer the option to sell your equipment. Iridia's store on Arc only sells items - no buying.
The only exception is the option to dismantle unnecessary weapons. You can choose this step after visiting Delta's Fix Pit workshop on Arc. When a weapon is highlighted, press the disassembly key. Thanks to this action, you can get some parts (Weapon Parts) and improve more useful pouches faster.
The decision to dismantle the weapon is irreversible. Always check if you have chosen the weapon you really want to get rid of. Otherwise, you can lose something useful irreversibly. Also, do not select disassembly just because you already own the weapon. It can still be very valuable if it has high statistics. Nothing prevents two different team members from using e.g. the same rifle.
