About the game
You command an army in real time on the war-torn planet Kronus. You build a base, capture resource points and send squads into fights where cover and unit abilities matter. There are four factions, the Space Marines, Orks, Necrons and Adeptus Mechanicus, and each one has its own campaign. Together the campaigns hold more than 70 missions.
The campaigns support co-op, and so do Last Stand and Skirmish. In Last Stand, you and two allies choose heroes and hold out against waves of enemies. In a team skirmish against computer opponents, two players can fight side by side.
It is real time, so there is always something to build or fight, and it suits friends who like to plan an attack together. It is planned for PC on 3 December 2026.
