"Berserked!!" is a fantasy multiplayer game, where 10 or more player get teleported into a big map. There, they can kill each other at any time.
BUT
Here's the catch, one of the player will be selected as the "Berserker". No one but that player knows who's the Berserker, and they are way stronger than normal players, as strong as 4 players combined, so then it becomes a psychological battle. The players have to find who the Berserker is, cause if they kill the other non-Assassin players, their chance to kill the Berserker will be slimmer since they need to work together to kill Berserker.
The win condition is simple, if the Berserker manages to kill all players, he/she wins and get a bunch of points. If the players manage to kill the Berserker, the surviving players win and get lots of points and the dead players will get a tiny bit of point. Once a round is over, a new Berserker will be chosen randomly, as well as a new map. After all rounds is over, all points will be counted and the players with highest points get bigger reward.
There will be different classes, each will different fighting styles. This will be a tactical play for the Berserker since he/she would need to try to snipe out the healer/DDs first. One important point is the fact that there's to team and everything is Free For All.
