Players install the game and go. The advantage of this style is that it focuses each team by giving them one objective instead of the two in the traditional, two-flagged game. In Overload, each team has a skull in an obelisk. The point of the game is to destroy the enemy's obelisk, but it isn't easy. The skull takes 1500 points of damage to destroy and repairs 15 a turn.
Victory requires getting a lot of team members shooting a lot of weapons.
The coolest new game is Harvester. In it, when a player is killed, a skull appears in the center of the arena. To win, players grab the enemy skulls and carry them to the enemy stronghold. If the player gets killed along the way, the skulls vanish. This doesn't take quite the skill or cooperation that the other games do, but it is just flat-out fun.
