Quite simple. 1 person presents a worst-case scenario, then the person below has to try and reach the objective. Then it continues, the person who reached the objective must post another scenario. Example: Person A: You're surrounded by 5 monsters and all you have is a knife, a boomerang, and a shovel. You have to sprint to a door and you'll be safe. How will you get to the door? Person B: I throw my boomerang at 3 of the monsters, throw a knife at another and KO the 5th with my shovel, then run like hell towards the door. Someone is about to slit your throat. You're bound and gagged to a chair and he's about to slit your throat in seconds. How do you turn the blade on him, break free, then escape? Etc. etc. etc. Allowed powers: Telekenesis Portal Machine All right... I'll start. You're in a room with no doors, windows, anything. All you have is a portal machine, and to escape you have to go to a room that is impervious to a portal machine, which is next door. How do you escape?
