Playing an another one of the flash games from my childhood.
Now I am playing Boxhead 2Play Rooms, which was made by Sean Cooper in 2007.
It's a zombie survival game, where you fight the zombies and devils. There are four selectable characters: Bind, Bert, Bambo and Bon.
There are many weapons to receive besides a pistol: UZI, shotgun, barrel, grenade, fake walls, claymore, rocket, chargepack and railgun.
At the moment I have not reached the max level yet.
