Right now we're having an insane slig fight, every man for himself with about six competitors, and if you get shot you tragically get teleported back to the entrance. We could probably make some interesting 'King of the Hill' style competitions like this: We select a square and all you have to do is stand in the specified place; of course there are half a dozen other people, all with guns, who are also trying to stand there too.
EDIT:
Someone was asleep at there post, so I got up to mischief...
Secret Agent Sliggy: Super Sneaky Time!
Anyone got a match?
