Mortal Sin | Terrifying Indie Horror Survival

Mortal Sin is an indie horror roguelike that drags players into a nightmare of brutal melee combat and suffocating tension.

From developer Nikola Todorovic, Mortal Sin is a first-person horror roguelike that’s been creeping up the Steam charts since its full release. With fast-paced melee combat, procedurally generated dungeons, and a suffocatingly dark atmosphere, it’s a game that pushes players to survive not just monsters, but their own panic.

With 3,000+ reviews and a 95% positive rating, this indie nightmare is already carving out a place as one of 2025’s most acclaimed horror experiences.

Why It Stands Out

• First-person horror roguelike: Rare to see the genres blended so effectively.
• Weighty melee combat: Every swing feels brutal, with risk baked into timing.
• Atmosphere overload: Suffocating darkness, grotesque enemies, and procedural dread.
• Replay value: Each run is unique, keeping the terror fresh.

Developer Spotlight

Mortal Sin is the brainchild of indie dev Nikola Todorovic, who’s been refining the game since its Early Access days. Working largely solo, Todorovic built a game that combines visceral action with indie horror atmosphere, showing how small teams can deliver intensity rivaling AAA efforts.

Final Thoughts

Mortal Sin stands out as one of the most intense indie horror roguelikes in years. It proves that small developers can deliver an experience as frightening and mechanically sharp as anything from larger studios. With every new run, the combination of relentless melee action and oppressive atmosphere keeps players on edge, reminding you that survival is never guaranteed.

If you’re searching for a horror game that blends roguelike unpredictability with visceral combat, Mortal Sin deserves a spot on your radar. It’s a chilling, brutal journey that rewards those brave enough to step into the dark again and again.
