Eyes locked on your prey.
You kill without remorse.
After all… it’s either you or them.
Sentience fades. This moment is your release.
Mortal Sin is built around fast, visceral melee combat where every strike matters. Chain slashes, bashes, and kicks into devastating finishers as limbs fly and blood paints the walls. Combat thrives on momentum: move fast, hit hard, and never give your enemies a chance to breathe.
Descend into a surreal, ever-shifting nightmare. Procedurally generated levels, randomized quests, and hundreds of hand-crafted rooms make every run feel fresh. Unlock a growing roster of distinct classes, from the greatsword-wielding Berserker to the gun-toting Pirate, each with their own playstyle and wild synergies.
Dive into a bold, graphic novel-inspired world that’s as stylish as it is deadly. Prefer a different look? Mortal Sin now features multiple visual modes and color palettes. Your nightmare, your way.
