Dragon Angel recently completed his analysis of the second screenshot to appear on the Heroes of Might and Magic V teaser site. While the second screenshot does not contain as much information as the first one, it gives us a good idea of what the new Inferno/Chaos faction will be like. However, the background is also a bit plain compared to what could be seen in the first image. Have another look at the Inferno screenshot here.

While you are there, check out the higher quality versions of all four screenshots, straight from Nival. Bigger is definitely better!
