Boxhead: The Zombie Wars

[Fortress]

Whoever here wants to play flash games at all, here's a pretty entertaining one. you play as a cardboard box version of what appears to be an extremely diesel Rambo, armed with a shotgun, pistol, exploding barrels, and a variety of other weapons, you face down the zombie forces and their boxhead terror. Go, Comrades, enter hell.
