Oddball

Oddball, is a multiplayer game-type featured in the Halo series. The objective is to locate the skull(s) on the map and to have possession of it, for the longest time possible. The default settings allow the game to be a free for all with 1 skull on the map, which you need to have possession of for 2 minutes in order to win. This game can be played as a Rumble Game or a Team Game where the highest score of the lone player (Free-For-All), or on a team's accumulative score, chooses the victor(s). Normally, a player who has the oddball is the immediate target for the other players, which is what makes Oddball an extremely fast paced and fun game-type. While a player has possession of the Oddball, they cannot wield their weapons or throw grenades. However, they can still melee opponents with the skull, which normally inflicts massive damage. The settings for the game can also be altered to make it more interesting. For example, the player with the oddball can go invisible or can be slowed down. The number of oddballs, on the map can also be changed. The Oddball takes the form of a skull.Oddball, in Halo 3 is the same and looks just like the skulls of Halo 2.

Trivia

 * Oddball, is derived from Marathon's "Kill the Man With the Ball".
 * The skull itself is from Halo's early development: when the player goes to rescue Captain Keyes in the level Keyes and discovers that he has been consumed by the Flood, the Master Chief was to burn through the Proto-Gravemind biomass and pull out Keyes' skull to get his neural implants. However, this was cut due to the flamethrower being removed, and possibly the burnt skull being too disconcerting to present in the game as well. The design of the skull, was apparently kept for the Oddball skull, as a Command Neural Interface resembling that of Captain Keyes can be seen on the base of the skull.
 * The player, holds the skull in a different position in every game. The exact reason for this is unknown, but is more than likely artistic liberty.
 * Just like in campaign, the skulls have numbers (though difficult to see) to see on top of their head.
 * In Halo 3 Multiplayer, if you melee an enemy with the Oddball it is an instant kill, however, the MLG variant changes this, so that two melees with a ball are required to kill a person.
