Bring loot home
Take stolen items back to the hideout between missions to use them as decorations. After the farm, pick up a chicken you’ve brought back. The interaction prompt lets you put it down or hold the throw input to toss it.
There’s no announced guarantee that individual items stay in the same spot after a restart.
Can you keep a hat permanently?
Permanent hat unlocks are planned for the full game through the cosmetics menu. Don’t count on a hat found during a demo raid to act as a permanent unlock.
