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 minutues 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 gametype. 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 do look just like the skulls of Halo 3.

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 burnt skull being too disconcerting to present in the game. 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 it was most likely to keep variety in the games.
 * Just like in campaign, the skulls have numbers that are hard to see on top of their head.
 * In multiplayer Oddball, if you melee an enemy with the Oddball it is an instant kill, however, the MLG variant makes it so two melees with Oddball will kill a person.
