More than a standard expansion, Lord of Destruction not only added content in the form of new character classes and an additional scenario, it also dramatically revamped the gameplay of the existing Diablo II for solo and especially multiplayer. Unlike the original Diablo's expansion pack ( Diablo: Hellfire), it is an official expansion designed by Blizzard Entertainment. Diablo II: Lord of Destruction (commonly abbreviated LoD) is an expansion pack for the popular Action Role-Playing game Diablo II.
