HoMM 5 >Towns and Creatures
The six towns that were in HoMM4 will also be in HoMM5, as well as two new towns. The Archeon town is based in the gigantic underground domes of Axeoth. The native terrain will be the swamp and the creatures will be from the HoMM4 Chaos town, the HoMM3 Fortress town and some of my own creation.
The Alchemist town consists of technology (but still within the scope of fantasy) and of units from the Life and Order towns of HoMM4, as well as a number of creatures from my own creation.
The towns works by the principle of HoMM4, which is by choosing a creature of each level, except for the first one. That makes a total of seven creatures per town. Since I believe that there should not be more than 7 or 8 slots per army, the players will probably have to make a choice on which creatures to use and which to leave home, in order to make room for heroes (who should be on the battlefield as well).
