The Heroes of Might and Magic V expansion will feature the new Dwarf faction. The dwarves, although short in stature, are warriors and practitioners of rune magic, and reside in the most hostile regions of Ashan

Hammers of Fate will also introduce new spells, abilities, buildings, artefacts, single and multiplayer maps, and a whole new campaign with 15 missions. The developers are even including a random map generator, so you should always have something new to try out.
