Heroes of Might and Magic V: Tribes of the East

"Tribes of The East features many previous bugfixes and improvements to the gameplay itself, left undone since the release of Hammers of Fate. A new faction was added to the game: the Stronghold. Moreover, an additional upgrade was added to all dwellings, which acts as the alternate upgrades of Heroes IV. The player is, however, able to choose between the two upgrades whenever a type of concerned creatures is being hired. The actual upgrade is also not permanent; a player can choose to change the creature to the other upgrade for a small fee.

Continuing the Hammers of Fate story, three full campaigns linking a single storyline are included. The first involves the Necropolis faction, featuring Arantir (the antagonist from Dark Messiah of Might and Magic). The second focuses on the new Stronghold faction, starring the Orcish leaders Gotai and Kujin. The final campaign is primarily focused around the Academy faction, involving the return of the Wizard Zehir from the base game, along with an alliance of other factions against the demonic Inferno armies. There is also a prologue campaign, consisting of a single mission, that introduces the Orcs.
The combat interface features are redesigned to allow easier access to certain spells, including Rune Magic and Might abilities. New spells have been added with the intent of rebalancing the combat and adding more content to the gameplay. The options for in-game and combat modes have a slight redesign for new settings, such as the creature's health change indicator and life bar span.

The map editor is redefined to support campaign creator and feasible to support the previous versions of game maps along with expanded terrain and texture creation possibilities. Model editor for the standalone product only can also be part of the game package upon release.

Many items are now part of a set that provides additional bonuses when worn together. They are also carried over between missions in the campaigns provided that the hero carrying them appears again. Some of these bonuses are specific to one type of hero, others can be gained by all of them.

Some racial skills have been reworked, particularly Necromancy. Instead of raising only skeletons, Necromancers can now raise any Necropolis unit provided they can pay enough Dark Energy and suitable corpses are available - for instance, Bone Dragons can only be raised from slain Dragons. The dark energy is renewed every first day of the week. "
