Over the last day or so, complaints have cropped up from players who’ve been trying to play the latest installment of the long-lived Might & Magic series. Users have turned to the game’s official Ubisoft message boards and Steam forums to vent, citing missing music, corrupt installation files and game freezes that prevent them from playing the game that they bought. The breakage appears to coincide with the game’s Shadows of Darkness add-on, which rolled out yesterday. When contacted, Ubisoft told Kotaku that they're working on the problem: “We’re aware of the issues players have been experiencing with Might & Magic Heroes VI: Shades of Darkness, and apologize for any inconvenience caused. We’ve now successfully restored content through a server upgrade, and are monitoring the situation closely. Meanwhile, we also encourage players to follow the steps detailed here.” It’s not clear if the problems with Might & Magic Heroes VI are stemming from the game’s need to connect to Ubisoft’s uPlay service or for some other reason. Kotaku has contacted UbiSoft for clarification and will update this story if they respond.
