Halo: Combat Extreme

Halo: Combat Extreme is a new form of the video game Halo: Combat Evolved. It is non-canon, as it has many enemies and weapons that do not appear in Halo: Combat Evolved.

Overview
Although the game itself is technically a remake of Halo: Combat Evolved, it is extremely different. The biggest difference is that instead of multiple levels, it is just one massive map.

Main Map
The Main Map (as it is called) is a collection of all the areas in the game. You cannot access certain areas until you have completed the previous campaign mission (ie if you don't complete the level "Halo", you cannot access "The Truth and Reconciliation". The map also features "ambient life", including blind wolves, thorn beasts, Flood Thrashers, and many other types of animals. There are two versions of the Main Map:

Campaign MM
The Campaign main map has blocked off areas that are inaccessable until certain missions are complete. It is large, but can be traversed easily with teleporters and vehicles. It has AI enemies that you can fight even if you're not playing a level.

Multiplayer MM
The multiplayer main map has all the areas unlocked, and allows players from all around the world to play on the same map. The multiplayer map also has AI enemies to fight, so it makes the massive Slayer match harder, and adds a touch of firefight.
