The kill bot appears in the Co-op Missions mutator "gift exchange" as one of the possible rewards for Amon when he or his forces gain a gift. The robot is invulnerable, but has a kill counter above its head. After a certain number of kills, the kill bot destroys itself. The number of kills required varies depending on what time the kill bot appears, if before 10 minutes, it takes 30 kills, but if after 10 minutes it takes 50.
