The main quest sends you to St. Lazarus Cathedral to meet “The Hive Mind”—a colony of infected who achieved symbiosis.
Before entering: Ensure your infection level is between 60% and 65%. If it’s lower, stand near a corpse pile to absorb ambient parasites (hold square). If it’s higher, use your last Slow-Release Capsule.

A giant mass of fused bodies.
Attack pattern: Slam (ground AOE), Tongue Grab (instant kill if not broken), Larvae Shower (homing projectiles).

Marta is already infected at Stage 3. She vomits corrosive bile.
Strategy: Do not shoot her body. Shoot the IV bags hanging above her. The antifungal fluid inside stuns her for 8 seconds. Then, use the pharmacy’s gas stove to ignite the puddle of bile. Repeat twice.

Parasite Infection is a text-based interactive game that focuses on themes of sci-fi horror, transformation, and survival. The player takes on the role of a protagonist living in a futuristic setting who becomes infected by an alien parasite. The gameplay loop revolves around managing this infection, balancing the loss of humanity against the acquisition of alien powers, and navigating a complex social hierarchy aboard a space station or colony.
Unlike traditional games with a fixed endpoint, Parasite Infection is heavily procedural and narrative-driven, focusing on "bad ends," transformations, and branching paths rather than a single linear victory condition.
