Posthuman's Progress

From the introduction:

Posthuman’s Progress is a freeform live-action role-playing game for 5 players plus one facilitator. It has been conceived as a game in which not all characters are created equal, but every player nevertheless holds power over the narrative. It is a game about conceiving different outcomes to events that take place over a very short period of time, and what the long-term effects of those events might be. At the same time, this is not a contemplative game by any stretch of the imagination. It should be fast-paced, improvisatory, and seriously playful.
