Mark of Cain

What FPS was meant to be: fast, brutal, and just a little bit cursed.

Mark of Cain is a retro-inspired 2.5D arena shooter in the blood-soaked spirit of Doom, Quake, and Ultrakill but with a twisted edge all its own.

Play as John Demonhunter, a demon-slaying Greek badass cursed by God Himself to suffer eternal life—and eternal combat.

After centuries of slaughter, John got cocky.

The big guy upstairs took offense and branded him with the Mark of Cain a glowing symbol of divine punishment that ensures he can never die… but also never rest. Now Devil, seeing a golden opportunity, unleashes wave after wave of hellspawn, meme-fueled bosses, and cursed chaos to make John's unkillable life a living nightmare.

Welcome to a world where every demon is an inside joke, every death is a punchline, and survival is just the setup for the next round of absurdity.

FEATURES

Classic Arena FPS Madness
5 weapon loadouts, secrets, blood and dopamine. Inspired by the best of the '90s but unshackled from nostalgia. Run, gun, bunny-hop, wall jump, and blast through dense enemies in tight, explosive maps.

Old-School Campaign Mode

Battle through the campaign inspired by Quake and Doom, featuring episodic content released for free as development progresses. Each episode expands the lore, introduces new enemies, and pushes John Demonhunter further into divine damnation.

Breakcore Soundtrack (Made by Me, Because Who Else Could Handle It?)

Rip and tear to an original breakcore soundtrack composed by the developer pure chaos, distortion, and adrenaline.

Making Fun of The Whole Genre
Face off against bosses that mock modern gaming, from the Ad Boss who spams you with unskippable ads every time you get hit, to the Tiny Flea who exists solely to shove you off ledges while insulting your skill.
