Wounded

Publishers blurb:
Wounded is an experimental roleplaying story game where players take on the roles of interviewers and “targets” (for lack of a better word), in an attempt to understand one another. As interviewers, the players wear many hats, like counselors or police. As targets, the players take on a single persona, creating backgrounds for themselves that grow more elaborate as the game continues.

Wounded can make for a fun ice-breaker game or even a murder-mystery mechanic.

All Protocol Games are 100% GMless, require almost no preperation time, and use the same game system. There are over 50 games in the series, which means there HAS to be something here for you.
