About Mark of Cain

Mark of Cain is a retro-inspired 2.5D arena shooter starring John Demonhunter, a demon slayer cursed by God with eternal life and eternal combat. After centuries of slaughter, John’s arrogance earns him the Mark of Cain, a glowing symbol that keeps him from dying but also prevents him from resting. The Devil sends waves of hellspawn and bosses against him, turning his unending life into a fight for survival.

Combat and movement

You run, shoot, bunny-hop, wall-jump, air-dash and slide-kick through tight, explosive maps filled with enemies. The game has five weapon loadouts, secrets and blood, and its movement system makes speed central to survival.

Campaign and bosses

The campaign unfolds in episodes, each expanding the story, introducing enemies and pushing John further into divine damnation. Bosses include the Ad Boss, which spams unskippable ads whenever you get hit, and the Tiny Flea, which tries to shove you off ledges while insulting your skill. The game also features meme enemies, bizarre dialogue and meta jokes that break the fourth wall.

Multiplayer and custom arenas

Four players can play together in split-screen, each as John Demonhunter. A built-in level editor lets you create arenas, and Steam Workshop support lets you share them or play other players’ creations.

Soundtrack

An original breakcore soundtrack accompanies the combat, with distortion and a chaotic, high-energy sound.
