Players could just launch the game and start playing. Over time, though, FPS games have added plots, skills, stories, moves and powers. They aren't as quick to learn and play as they used to be.

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.
