Get ready to sharpen your blades and test your reflexes — Mortal Sin, the blood-soaked first-person roguelike from solo developer Nikola Todorovic, officially leaves Steam Early Access and launches Version 1.0 on August 29, 2025.
Since first hitting Early Access back in 2023, Mortal Sin has built a reputation for its striking graphic-novel visuals and savage, skill-based melee combat. What started as a gritty, chaotic roguelike has now been transformed into something far bigger, thanks to years of community feedback and a total overhaul of the game’s core systems.
Gone are the simple boxy mazes of the early builds — in their place are richly detailed, labyrinthine environments packed with enemies sporting smarter AI and deadlier attacks. Combat has been rebuilt from the ground up with new animations and a more fluid feel, while entire systems, from skills and items to combos and classes, have been reimagined to add depth and variety. The result? A faster, bloodier, and far more rewarding roguelike that’s already sitting with Overwhelmingly Positive reviews on Steam.

And Todorovic isn’t stopping at launch — a post-release roadmap is already planned, promising even more content to keep the chaos flowing.
