Because modding is often used for cheating, it is not allowed on Xbox LIVE and the use of a modded Xbox on Xbox LIVE will result in a terminated account.
Some mods involve the alteration of game resources, while others run independently of a game and edit its working memory. A number of things qualify as mods, ranging from palette swaps to the creation of entirely new maps. Modding is the act of altering aspects of a game by manipulating its program code and other resources. Through modding, the player wields two Energy Swords at one time which is not possible in normal gameplay.
