Painkiller: Resurrection is a first-person shooter based upon Painkiller and Painkiller: Overdose. It is not a sequel to those games, but instead rehashes the familiar theme with a new protagonist, updated graphics and improved special effects.
You take the role of William "Wild Bill" Sherman, a Black Ops specialist and former CIA agent. Bill's last mission went completely wrong and he was killed as were many innocent bystanders. Now he has arrived in purgatory, that interim place between heaven and hell where good and evil forces collide.
There are four difficulty levels in the single player game. As in other FPS games, your objective is to kill monsters and beasts and make it through the levels. Unlike previous Painkiller games, there are different ways to solve things, some less violent than others. For instance, you can sneak around areas where enemy spawning is likely.
Each of the eight weapons has different attack modes plus two firing modes. Besides standard guns there are outlandish weapons like a razor-spinning grenade launcher and a demon head that spews laser fire. Find additional weapons, ammunition, armor and gold by killing foes and destroying containers (urns, caskets, boxes etc.) Some objects can also be pushed.
Health can be regenerated somewhat by walking through the soul left over after killing an enemy. Gather enough souls to morph into a demon for a short time. As a morphed demon you become somewhat invincible and immune to normal attacks until the effect wears off.
Special abilities and powers can be gained by finding hidden Black Tarot Cards contained in each level (single-player game only). The multiplayer game has other power-up tokens that provide similar effects.
All movement is controlled using your keyboard, and the mouse is used to turn and control the direction you look and aim. Keyboard keys can be reassigned if you desire. The Video Options include being able to toggle between a Full Screen and Windowed display.
