Halo mods
From Halopedia, the Halo wiki
Did you know you can alter the maps in both multiplayer or singleplayer games? (note most mods work on Halo pc Trial, Halo full version, and Halo custom edition). Well Altering the maps is called MODDING. Modding lets you alter maps to make weapons more destructive, add more areas to explore, add AI (multiplayer only), or add more vehicles that arent normally availabe. There places all over the net that give mods for free. Just go to google and enter "Halo PC Mods". Then you just follow the instructions. Some come with a notepad file with instructions. Some require the use of a ppf machine (only 3mb, widely avaialbe). Modding is really intresting, try it today!!!
