Halo Custom Edition Portable

Halo Custom Edition is a multiplayer-only stand alone version of Bungie's sci-fi shooter. Halo CE includes several new multiplayer features and options, the most notable of which is the ability to play user-created content. This add-on is unsupported and does not require a Halo CD and Key to install, but all who download are stating they have purchased and currently own Halo: Combat Evolved.

Great for playing at school/work over a LAN. (Many shools/workplaces ban the use of exe's named Halo, so it is named H4L0).
