The game takes place in the universe of Warhammer 40,000: Dawn of War, on a planet called Tartarus.

You play as Gabriel Angelos, the commander of the Space Marines, who comes to the planet to fight the Armada of orcs because they have become a real problem of the star system. Later he learns that the Chaos forces are the leaders of the Orcs. The Sorcerer, Sindri Myr betrays his master, Baal. Then Gabriel was betrayed by his friend, who gave the sorcerer Sindri Myr a mystical artefact – Maledictum, but despite this, Sindri Myr leaves Isador to fight alone, and he dies. Sindri uses the stone to turn into the Daemon Prince with the stone’s power.

The player is given the opportunity to collect resources and spend them on the construction of the base, the development of technology and the creation of military units. However, in this game, much attention is paid to the tactical component.

Fights, as a rule, are not large crowds of troops, but small groups of 4-8 people and the number of military equipment is calculated units. There are also personal limitations. For example, the number of Orc races and chaos builders is limited to 4-5 units.
