Endoparasitic is an action game that throws you into a horrific situation from the start: all but one of your limbs have been ripped off and you are living with an alien parasite in your body. Somehow, you must crawl through your research facility with a single arm, fight off mutated creatures, preserve your research, and above all, survive.

The controls of Endoparasitic are extremely simple—everything is controlled through the mouse. Like a single arm, you must do everything manually using this control. You must move around, pick up guns, aim, fire, and reload entirely one-handed.

To survive, you must crawl stealthily through several sections, avoiding monsters that will quickly surround you if you get caught. If spotted, you must fight off the creatures using your arm, your guns, and your wits. Your health bar is measured by the distance the parasite has to travel to your brain, so you will often have to find and use various serums to prolong your life. Collect four types of guns and fight against horrific bosses in your quest to protect the fruits of your hard work. Endoparasitic is a short but grisly action experience that's not for the faint of heart.
