Frozen Hearth

Frozen Hearth is a real time strategy game set in a fictional world known as Ámorrá. The game features two playable races: The warrior tribes known as Danaan, and a mysterious race of ice-monsters known as Shangur. The campaign part can be played in cooperation mode with two players. Like in Warcraft III, the player can control a special powerful hero unit, known as Avatar and Demiurge for Danaan and Shangur respectively. Another important game element is limitation of upgrades. For example only six of twelve available buildings can be build in each game. Also several units can specialize in only one of several possible directions.
