Gravity RPG

Gravity is a one-shot, GM-less RPG for 3-5 players about people who may or may not get along, trapped in a situation which is slowly but surely constricting around them, removing their options one by one until they're scrambling to cope using whatever they have left. It can cover teens in a haunted house, fantasy politicking while zombies invade, superhero rivalries while a crime wave is happening, even just rich people being horrible to one another.
