No idea if it was suggested here before but I'll go for it:
The event is called The Hunger Games. (Yes, the survivor event but with some modifications).
Instead of being on a random map like Mansion or Town we could make a real Hunger Games arena and put some high pedestals in there with player weapon clip so you can't shoot other people while you're inside the pedestals, and also put player blockzones around the pedestals for when you step out you can't climb back on. All pedestals will surround the cornucopia (where the HP, AP and Ammo spawns are).
Room mods: None. (No [IA] nor [R], why you ask? Because the spawns at the center of the map are to make things more interesting).
The rules follow the Hunger Games series:
24 players will fight until death. Last one alive wins.
Players CANNOT leave the pedestals until given the signal by the event hoster. By doing so he will be shot down and kicked out of the room.
Players who died will be kicked out of the room.
Teaming IS allowed! But there must be only ONE winner.
Basic rules such as no force lagging, spiking, n-stepping apply in here too.
Once 5 players are left the event hosters may offer "treats" to players such as meds (or landmines c:< )
The last player alive wins 3 points. The second last player alive wins 2 points and the third last wins 1 point.
