Halo Custom Edition

Halo Custom Edition, sometimes abbreviated Halo CE, is a free stand-alone expansion for Halo: Combat Evolved by Bungie Studios, which was ported to the PC by Gearbox Software. Halo CE was released by Gearbox as an unsupported add-on, which requires the original game.

Features
Halo Custom Edition has the ability to load and play user-created content and maps created with the Halo Editing Kit. Many custom levels have been created by dedicated members of the modding community and have been posted for download at a plethora of websites.

Custom maps may contain entirely new content, including:
 * Level geometry
 * Weapons
 * Vehicles
 * Player character
 * Sounds
 * Game interfaces
 * Level scripts & interactivity
 * Objects
 * Special effects
 * Animations
 * HUDs
 * Single player modifications

An arguably better netcode was put into Halo: Custom Edition, as well. It noticeably reduced leading for some, but for others it made it more erratic. Also, a Rules feature can be activated by pressing the F2 button by default. It displays all of the specifics for the gametype currently being played on the server.

With the Halo Editing Kit, AI Covenant, Marines, and Flood can also be added.

Community
Several modding communities have emerged since the advent of Halo CE. One of the most prominent communities is Halomaps.org. Modders use the Halo Editing Kit to incorporate custom models, images, physics, and data into an easily distributed .MAP file.

Halo Editing Kit
Halo Editing Kit, commonly referred to by its acronym, HEK, is a repackaging of the development tools that Bungie created and used in the development process of Halo. The Halo Editing Kit was released for the creation of custom content for Halo Custom Edition. It is a free, unsupported add-on released by Gearbox Software.

This editing kit includes Guerilla, a game resource and tag editor, in addition to Sapien, a mapping and object placement editor, and Tool, a map resource compiler. Most original content must first be modeled in 3ds max (or Gmax) and then converted to a HEK friendly format using the Blitzkrieg exporter and Tool to be edited or added to a custom map.

Other
There are also 'cheats' for Halo CE, called Developers Mode, more commonly called devmode, or also known as dev. It is used by map designers to test out maps they make. It can also be used to cheat in single-player maps that can be downloaded. However they can only be used in single-player maps because when dev is activated, the host can only start a server through LAN. The only way for it to work in multiplayer is to download a small app which allows you to enable or disable devmode without restarting the game, thus allowing you to enable it within a multiplayer game. Even then most of the cheats can only be used by the host. To Play Halo Custom Edition you must download it and have the Halo PC/ Halo Custom Edition Key and CD Rom.

Some of the "Dev mode" cheats are:

"Bottomless Clip" Never have to reload, plasma weapons never run out of battery or overheat.

"Deathless Player" No one can die.

"Infinite Ammo" Weapons will need to be reloaded or may overheat, but a player will never run out of magazines or battery

"Super Jump" Allows a player to jump significantly higher then normal. Best used with the "Deathless Player" cheat or the "Jet pack" cheat so player do not die on impact.

"All weapons" All weapons will spawn around the player, including the two flags and an oddball, regardless of the game type. If these are touched in non team games, it can cause the game to glitch.

"Spawn Warthog" A chain gun warthog spawns beside the player.

"All Vehicles" 1 of every vehicle spawns around the player, this can only happen in maps that support vehicles, including any custom vehicles a map may have.

"Jet pack" Players will not take damage from falls.

"All Powerups" An Active Camouflage and an Overshield will spawn beside the player.

"Medusa" Anything that moves its cross hair over a player using the cheat will automatically die.

"Bump Possession" Used mostly in custom maps that have AI. If a player touches into a hunter, elite, jackal, grunt, flood combat form, flood carrier form, marine, or a spartan AI, they will automatically gain control of it. But the player may not gain some of the abilities of that character. If you posses a hunter, you will not be able to do its melee attack. Bump possesion is Very glitchy in Internet multiplayer.
