Glock 18

The Glock 18 is your first automatic gun. It is purchasable on the first floor. It is purchasable after buying the Deagle. If you have a sniper problem, than this gun is most likely the solution. For PVP it's supposedly better than the Deagle, but for fending of zombies I'm not quite sure if it's better.

After purchasing the Glock 18 you can buy the MP5A3. For surprise attacks is it pretty good, as your victim is dead before he can react. If using the Deagle or M9, he can anticipate at the first shot, and fight back. This can be a problem when facing invaders.
