About the game
You play a soldier in a small team sent into zombie-filled areas. In objective missions you plant explosives in an infected zone, then get out fast. In survival mode you hold out through waves of zombies, and between waves you restock with new weapons and equipment.
Up to five players join online, and each picks one of five classes: Pointman, Support, Assault, Technician or Sniper. Every class has its own gear and play style, so the team covers for each other. You can also play offline, with or without computer teammates, and the difficulty adjusts to the number of players.
It is a fast zombie shooter where every class has a job. It is free on Windows and Linux, so friends can try it without buying anything.
