Downloadable Content

Downloadable Content or "DLC" is the name for a system update on Microsoft's Xbox LIVE. For the Halo games, DLC is generally split into two variants: Title updates and map releases. Map releases are more common and are in every game except Halo: Combat Evolved (as Xbox Live was not released to the public at the time). They are bought with Microsoft Points over the Xbox Live Marketplace. Title Updates are better known as "patches", and are normally used to fix glitches in a game, but can be used implement new things into games without the need to buy them.

Trivia

 * Halo: Combat Evolved is the only Halo game without some sort of DLC, as Xbox Live was not released to the public at the time.
 * All of Halo 3's map packs are named after difficulties in Campaign and Firefight.
 * Achievements contained in a map pack will appear in the list of achievements for any Halo game, but can't be unlocked until the DLC is downloaded.
 * The third Halo: Reach map pack, the Anniversary Map Pack, contains the remakes of the seven Halo: Combat Evolved maps, as well as the Firefight map Installation 04. However, the remastered completely original maps are only available on Halo: Combat Evolved Anniversary.
