Ok I so I set up a few servers to try out tonight. The descriptions are below. They seem to work find although some graphics seem to be missing. Not sure if it's a configuration issue or if the graphics can't be rendered in the DC version for some reason.
-Freezetag is similar to the game you played in elementary school. When a person gets killed, they become frozen, and they will melt when a teammate stands next to them. While frozen, a player can only spectate the game, but once they are melted, the player will then respawn and return to help their team out. When a whole team is frozen, the other team receives a point.
-Last Man Standing is a free for all or teamplay game style where once you get killed, you spectate the rest of the round. The last person who is alive receives a point and the round is over. Everybody will then respawn in and the next round starts. The object of the game is to be the last person alive, and thus, that player is the most deadliest or the most cunning at avoiding enemies.
-MuckleBall is the newest of the game styles. The MuckleBall is symbolized by a powerup, usually regeneration (but it can be anything). MuckleBall is played in free for all, and it is everyone's job to kill the person with the powerup/MuckleBall. Killing the person with the ball will give you points equal to the number of people in the arena. Killing a person without the ball is counted as a normal score, and will give you one point. Many people use strategy by letting their opponents weaken the person with the ball, then swooping in and quickly killing the opponents and the person with the ball in one fell swoop. This will both maximize points and will give you the ball. Once the person with the ball is dead, the round will stop, there will be a brief intermission, and then the next round will start.
