Pentagon Thief

Overview
The Thief is an enemy who appears on the Zombie Map "Five", replacing the Hellhound rounds. The Thief teleports around the map and steals the players weapons. The appearance of the Thief is somewhat like a mad scientist covered in a red aura and numbers. If the thief is killed a Max Ammo is dropped and the player gets their weapons back.

When The Thief arrives, it best to equip a bad, cheap, easily obtainable, or empty gun so that if he does steal from you, the impact is minimal. Preferably the gun should be light to also make sure that you can get away from him faster.

To avoid your gun being stolen in the first place make sure you have a light weapon like SMG's or pistols and make sure you have a large path that you can circle many times as you run away from him. Since you do run slightly faster than him with light weapons, teammates can pick him off while you run around the said path until he dies.
