Game 63: Boxhead - The Rooms

Use your savvy - and some BIG guns - to stave off the zombie apocalypse in this, perhaps the cream of the zombie-game crop, Boxhead: The Rooms.

This new version focuses on the game's most entertaining activity - blowing up hordes of zombies in a selection of confined arenas (with even more available in yet another sequel), using everything from shotguns, grenades and rockets to chain reactions of exploding oil drums.

Controls:

Arrow keys to move, Space to fire, 0-9 to select weapons, P to pause.

Tips:

Zombies can't get through a seamless wall of barrels (though you can), so sometimes you can "seal off" their entrance point(s) then just pick them off with grenades.
