Scavenger allows the player to see and pick up ammo bags left by dead players. These bags replenish one magazine of ammunition for each weapon the player carries and one lethal grenade.
The pro version allows the player to pick up one tactical grenade with each bag (excluding the Willy Pete smoke grenade) and spawns the player with maximum ammo.
Notably, Scavenger no longer replenishes weapon attachments, launchers and most equipment. If a certain amount of bags are picked up, the only pieces of equipment it is known to resupply is the camera spike and motion sensor.
