About this game

Welcome to Parasite Testing, where your creations don’t just live… they fight back.

Engineer deadly parasites, release them into test chambers, but you’re not just observing anymore—you’re part of the experiment. Parasites can infect you, mutate your abilities, and turn you against other players.

🔬 Features:
• Fight infected players—or become one
• Survive outbreaks inside dynamic test chambers
• Trigger mutations, destruction, and containment failures
• Experiment with different parasite presets

Open Alpha — new parasite types and features added often.

Can you survive what you create… or will the infection take over?
