Earlier this month Focus Home Interactive revealed that there is a new RTS coming set in the Warhammer 40K universe. The game is titled Battlefleet Gothic: Armada and is being developed in Unreal Engine 4 for the PC. Not much is known about the game but Focus Home Interactive promised to reveal more soon.
The game will be set in space and will feature the Imperial Navy’s Battlefleet Gothic against the Chaos Black Crusade of Abaddon the Despoiler. So it would seem that the Space Marines and Chaos factions are in the game but no further word on any of the other Warhammer 40K races. I have posted a few screenshots from the game below.
