Diablo II, sequel to the popular game Diablo, is a dark fantasy-themed Action role-playing game in a hack and slash or "Dungeon Roaming" style. It was released for both Microsoft Windows and Mac OS in 2000 by Blizzard Entertainment. Diablo II was developed by Blizzard North.
Diablo II: Lord of Destruction (commonly abbreviated LSurprised) is an expansion pack for the popular hack and slash Action role-playing game Diablo II. Unlike the original Diablo's expansion pack, Diablo: Hellfire, it is an official expansion designed by Blizzard North.
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. As a result, LSurprised is largely considered a "must-buy" instead of only being an addition, making it a huge multiplayer success and one of the most successful expansion packs of all time.
