Halo Custom Edition

Halo Custom Edition, commonly abbreviated Halo CE, is a standalone, multiplayer-only, expansion for the PC version of Halo: Combat Evolved. The expansion was released on March 15, 2004 by Gearbox Software as an unsupported version of the original game. Similar to its PC version, the expansion requires a key-code during installation.

Halo Custom Edition allows players to browse and play user-created content and maps created with modding kits. Modders would use the Halo Editing Kit to incorporate custom models, images, physics, and data into an easily distributed .MAP file, which is compressed and uploaded. The amount of custom content varies widely but is limited by the game engine's capabilities. A few examples of user-created content may include custom character models that uses an Elite biped instead of the default Spartan biped, a Call of Duty-inspired level or even special animations and effects for weapons, melee and reloading. Most of these user-created content and maps are available in dedicated modding community websites such as Modacity and halomaps.org.

Two small features were added to the game such as the ability to display the specific for the gametype currently being played in the server (by pressing F2), and the ability to display the name of all players in the same team above their respective green arrows (by pressing F3). Additionally, an arguably better net-code was put into Halo: Custom Edition as well. The game has noticeably reduced latency issues compared to Halo PC.
