After losing three limbs and becoming host to a lethal parasite, you must drag yourself through the corridors of an abandoned arcship overrun by nightmarish creatures. Every action-from moving and aiming to reloading-is handled manually with the mouse, forcing you to juggle mobility and firepower as you fend off hordes of twisted foes. Scavenge for scrap and biological material to craft ammunition for your weapons and synthesize vaccines that slow the parasite’s progress toward your brain. Along the way you’ll manage a tight inventory, confront mutated monsters and formidable bosses, and uncover the ship’s dark story as you fight for a chance at escape and survival.

Endoparasitic is a tactical survival horror game set in a secret research lab on a remote asteroid. After losing three limbs and becoming infected with a deadly parasite, your mission is to save your research. You must drag yourself through the lab's corridors, fend off horribly mutated monsters, inject numerous syringes of vaccines, and survive at all costs. The game requires you to manually perform every action, from reloading to moving, using only the mouse. You'll need to balance movement and firing while planning your approach to each room to avoid being overwhelmed.
