Carry your trusty sub-machine gun and enter a rampage in the shooting game Madness Regent! An unknown character somewhere in Nevada infiltrates a highly-guarded facility and you must survive through waves of enemies that will shoot at you on sight or punch you when you get too close. Move with the arrow keys, S to jump and A to shoot. The environment certainly favors the opposing party since you might always get surrounded and easily shot. Once you get inside the building, you won't be dealing with just humans, those that you killed will be back soon as zombies which attack in packs.
