"Stranded in a place between Heaven and Hell, your time of judgment is at hand. The Underworld is on the verge of unholy war, and you are but a pawn in the infernal battle. As you fight for your purification, the truths behind the deceptions are revealed."
Painkiller puts you in a world somewhere between Heaven and Hell, in action that surely resembles more Hell than Heaven. Fast-paced action and horror-themed world puts you on the edge of the seat on all times. The game world is created by a proprietary 3D engine called "PAIN engine", which provides amazing details with latest lighting and shadowing effects.
The gameplay, as said, is fast and frantic and you can and should shoot everything that moves. After killing an enemy, the soul can be consumed to gain health. Monsters also leave gold behind that you can use to upgrade weapons, speed, maps and more.
But the real key ingredient is the incredibly advanced physics provided by Havoc 2.0 physics engine. Havoc offers unseen realism in collisions and explosions as well as ultra realistic death animations, thanks to "ragdoll physics".
Painkiller includes multiplayer mode in which you can compete against other live opponents on Xbox Live with up to eight players in sever different modes.
