Callisto Protocol comes from Striking Distance Studios, the talented team led by game industry veteran Glen Schofield. Schofield directed the original Dead Space series, so Callisto Protocol carries serious survival horror credentials. The game launched in December 2022 across PlayStation 4, PlayStation 5, Xbox One, Xbox Series X/S, and Windows PC.
The game places you in the role of Jacob Lee, a character trapped in Black Iron Prison—a massive penal facility orbiting Jupiter’s moon Callisto. The setting is beautifully dark and atmospheric, with the prison becoming ground zero for a horror crisis that forces you to survive against impossible odds.

Callisto Protocol focuses on third-person combat and strategic survival over pure evasion. You’ll explore interconnected levels, gather critical resources, fight off infected prisoners, and uncover story details through environmental clues and recorded logs. The combat feels satisfying and visceral, demanding timing and careful resource management.
The game emphasizes melee combat mechanics and environmental interactions over heavy firepower. You’ll dodge, counterattack, and use your surroundings as weapons—a refreshing change from standard run-and-gun horror games. Encounters feel intense because ammunition is scarce and enemies are genuinely dangerous.
