Diablo II: Lord of Destruction is an expansion pack for the hack and slash action role-playing game Diablo II. Unlike the original Diablo's expansion pack, Diablo: Hellfire, it is a first-party expansion developed by Blizzard North.
More than a standard expansion, Lord of Destruction not only added content in the form of two new character classes, new weapons and an addition of a fifth act, but also dramatically revamped the gameplay of the existing Diablo II for solo and especially multiplayer.
