The sci-fi horror role-playing game Parasite Mutant now has a playable demo available on PC via Steam, offering an early look at the opening chapter ahead of its full release in 2026 for PlayStation 5 and PC.

Released by developer IceSitruuna, the demo introduces the core systems of Parasite Mutant through a guided tutorial, a short prologue sequence, and an explorable section representing a small slice of the overall game. The demo is designed to provide a focused first impression, with an estimated playtime of around 45 minutes depending on exploration and combat approach.
Set in a distant future, Parasite Mutant follows psionic agent Nova on a mission to an abandoned island city overrun by grotesque mutants. The demo gives a brief taste of the game’s unsettling atmosphere, blending survival horror elements with RPG progression. Combat revolves around the ATC system, which emphasizes timing, chaining actions, and reacting to enemy behavior rather than relying purely on turn order.
Visually, the game pairs a semi-realistic anime style with modern lighting and optional retro-inspired filters, reinforcing its blend of classic and contemporary design influences. While story details are kept deliberately minimal in the demo, the available area hints at puzzle-solving, environmental storytelling, and the larger mysteries waiting in the full release.
