Boxhead Rooms

We were a bit dismissive of the first Boxhead game when we originally compared it to Zombie Storm - your character occasionally disappeared if you didn't have the most up-to-date Flash plugin, and the levels took a while to get around.

The character-disappearing hasn't been fixed, but this new version at least 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.

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

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.
