Prey hasn’t been out for 24 hours yet and already players have found a way to exploit the game’s crafting system. The glitch in question allows you to duplicate materials, ammo and health kits with little effort.
To exploit the system, you will need to play through the game until you reach Morgan Yu’s office. Once you reach that point, you’ll find a Material Recycler. The purpose of this machine is to recycle materials freeing up resources so you can use them in your own crafted items.
Instead, fill up the Material Recycler with four piles of already-recycled items. Hit the button, you’ll now get twice as much of the item as you started with. Rinse and repeat for as long as it takes to stock up on ammo and medical packs.
If you want an easier time in Prey and don’t mind abusing the system before Arkane Studios fixes it then confirm the steps by checking out the video below:
