Cartonia

Who cares who this is! You just want to kill! Kill! Kill! Kill! You pounce on him pounding him with your fists! Wires pull out and alarms blare, a panel swings shut unoticed on your abdomen. You pound the man before you until there is nothing left recognizable. You are covered from head to toe in blood. The door into the room has slammed shut and locked during your frenzy but it is no match for your strength! You tear it off it’s hinges and make your way into the hall behind. It’s a maze of white non-descript halls and doors.

You pick a route at random killing all you come across as they cower in fear! Eventually you come to an exit, but you hear booted feet behind you moving in unison. Hmm... to escape or kill some more?
