Defuse the Situation
A cooperative multiplayer game wherein two or more players must use their very best communication skills to defuse a (mock) bomb!
A bomb "defuser" sits alone with the bomb while the "expert," separated from defuser and bomb alike, must provide instructions on how to disarm each of its modules based on the defuser's observations about its makeup and appearance.
Sound familiar? That's because this game is a physical adaptation of Steel Crate Games' Keep Talking and Nobody Explodes. I served as lead game designer and co-programmer.
