Painkiller

Painkiller is a "bullet hell" first-person shooter with a gothic storyline and frantic gameplay.

Players are cast as Daniel Garner, a regular guy who gets killed in a horrific car crash while taking his wife out for her birthday. She, being the saintly woman she is, gets admitted to Heaven. Daniel, due to his shady past, does not. He finds himself in Purgatory -- a place somewhere between Heaven and Hell. It isn't long before Daniel is recruited by his "caseworker for the dead" to fight the minions of Hell. Lucifer is plotting to overthrow Heaven, and is using Purgatory as a staging ground. The offer is simple: stop Lucifer's armies and earn Daniel's heavenly reward.
