Nordic Games has announced Mac and Linux releases of Painkiller: Hell and Damnation, the remake of People Can Fly's frantic FPS, along with a mod-kit for the PC version. Nordic says they'll be available sometime this spring, while the game is due out on Xbox and PS3 on April 5.

As for the mod-kit, it'll use UnrealEd and be integrated with Steam Workshop, letting players create items, weapons, multiplayer skins, new maps and games for the Painkiller experience.We can expect the beta for that sometime in April, so mark your calendars for lots of painkillin' around then.
