You'll have to wait a little longer for your fix of new Might & Magic Heroes content. Ubisoft has delayed the standalone expansion Might & Magic Heroes VI: Shades of Darkness and the Complete Edition (which will include the expansion as well as original MMHVI) hve been delayed to May 2, 2013.
Both were originally planned for release on February 28th, but now the two extra months will be used for polish, according to the team in today's announcement.
"This extra time will allow us to ensure a top quality game experience as we want this Standalone expansion to meet your high expectations. Meanwhile, we will continue to share more information about the game on our official channels", the statement read, along with an apology for the delay.
As a special bonus, Might & Magic Heroes VI players will be granted a map based on Might & Magic's Enroth next week.
