Emblems were first introduced in Halo 2. They are small designs that are associated with a Character Profile and used to represent a player's identity in multiplayer games and online play. They consist of a two-colored design or pattern overlaid upon a background (typically a geometric shape), with a user-selected color scheme applied to the result. The feature was later carried on into Halo 3, Halo 3: ODST, Halo: Reach, Halo 4, and Halo: The Master Chief Collection.
