The Pentagon Thief cannot be outrun and has high health. The Winter's Howl can slow him down, allowing you to run from him as long as you have ammo. The Ray Gun, Claymores, and "Mustang and Sally" are effective weapons for taking him down. If you don't have one of these weapons, it is possible to immediately kill him by baiting him into an Electrical Trap, however, he will try to avoid them.

Note: Only the player targeted by the Pentagon Thief can see him. Other players will only see floating red numbers.
