Not sure if Bonn-O wants to be in on the game or just the hot tubing.
Ok, well the idea is that you each represent yourself as your own Minifig Hero (Like the Immortals) with some extra skills/abilities, chosen weapons and maybe a special power or two and that you each work as a team (you are Dial 'A' Death a band of Immortal Mercs). You must work together to a degree against whatever the task is. You could think of it like a role-playing game without the cognitive problem solving or at least problems that can be solved violently. Obviously, although you will all be on the team together there will be secret motivations (objectives) and the drive to out do your team mates (points for doing/killing stuff).
