The Elder Scrolls III: Bloodmoon is the second expansion pack for Bethesda Softworks' The Elder Scrolls III: Morrowind. While it was originally released as an expansion set for Microsoft Windows, Bloodmoon is included within the Morrowind: Game of the Year edition for Xbox. This expansion adds new enemies, the East Empire Company as a joinable guild, and the possibility to become a werewolf, akin to the inclusion of vampires seen in Morrowind. Bloodmoon also uses larger and more detailed environments, including snowfall, thus raising the computer hardware requirements, though the ash storms of the original game are much more graphically demanding than the snow of Bloodmoon.
