Temporary Profile

A temporary profile is used in Halo 2 and Halo 3 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

 * Some temporary profile names are possibly referenced by Bungie, such as "Caboose" (which could be a deliberate reference to the popular machinima 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)".
