How loot chance works
The chance that a freshly spawned container, or a killed NPC, rolls at least one Tin Can Alarm. Container chances are before inventory limits: a full crate can discard rolled items, while bonus scrap drops beside it.
Raiding
Ignores 10% of explosion damage.

How counts and times are worked out
The splash filter describes sharing damage across walls, not collateral damage to players or nearby deployables. C4 and satchels do not share construction damage even when loose. Counts are for one target; visibility and distance determine possible splash.
Times are exact for melee and for anything fired: swings times swing delay, or shots times fire rate plus the reloads that forces. For a charge you place by hand it is one second per charge plus the fuse, and that one second is the only estimate here. Melee tool counts assume fresh tools, because repairing lowers a tool's maximum condition each time and that rate is not in the files we read. Vanilla server settings, contact range, no distance falloff.
Recycle & repair
Recycling
Per item at full condition. Green’s 60% boost needs 4 heavy fuses at the Power Plant; red requires maximum power (18 fuses).

How returns work
Component fractions are random rolls; Scrap fractions carry over between cycles. Worn items return less.
Repair
Repair bench cost when fully worn.

Repair cost rules
A half worn item costs half as much to repair. Rust stores no repair cost. The bench builds one from the crafting recipe: components are swapped for the first ingredient of their own recipe, then everything is charged at 20% and rounded up.

What to know
The alarm can throw its payload
Tin Can Alarms can hold a grenade, Supply Signal or other supported throwable. Crossing the wire triggers the alarm and throws the loaded item at the trap’s position.
