Temporary Profile

Temporary profiles are used in Halo: Combat Evolved, Halo 2, Halo 3, Halo 3: ODST, Halo Reach, and Halo 4 when players without profiles wish to play Multiplayer or the Campaign. When a player without a profile signs into a game, he or she will be asked if they would like the use a temporary profile.

Temporary profiles cannot be saved (and cannot earn any achievements in Halo 3). Temporary profiles are issued random usernames, tags, and emblems. Names include "Bozo", "Sausage" and "Caboose".

Trivia

 * Rooster Teeth used the temporary profile names to create the names of the characters in Red vs. Blue.
 * If a profile and a temporary profile play splitscreen over Xbox Live, the temporary profile will have the same gamertag as the other profile, with a number added. If, for example, "MyGamertag" plays splitscreen with a temporary profile, the temporary profile will show up as "MyGamertag (1)".
