Alien Brain Slimes

The Future of the Holy Mucilarchy depends on you!

Alien Brain Slimes is a tabletop roleplaying game where you play as alien infiltrators from the galactic empire of the Holy Mucilarchy, sent as advance scouts for a planetary invasion. Each player slime controls a human host body, but operating these crude biological machines requires constant skill and concentration. Simple tasks that humans perform automatically, such as walking, speaking, maintaining facial expressions, demand the complete attention of a controlling slime, and frequently, attempts lead to bodily malfunctions.

You won't be rolling persuasion or athletics in this game; rather, Forming Sentences and Limb Coordination are difficult skills unto themselves.

It's safe to say that staying undercover is not a simple task.
