"This is the Dawn of War that fans have been waiting for," said executive producer Stephen MacDonald. "Our biggest units ever? Check. Giant orbital lasers? Check. Base-building, epic heroes, huge battles, it’s all in there. Get ready for the biggest Dawn of War yet. For the Emperor!"
"Dawn of War 3 immerses players in the escalating brutality of galactic warfare, where they will lead elite hero units and colossal armies to victory, or oblivion," the press release adds.
"Powerful super-walkers will tower over the front lines as screen-shaking assaults blister the battlefield in an all-out, over-the-top spectacle worthy of the iconic Games Workshop Warhammer 40,000 universe."
According to Sega, Dawn of War 3 "combines the epic scale of Dawn of War, with the customization and elite heroes of Dawn of War 2."
It continues: "The result is a best-in-class edition giving players the rich strategic experience, stunning visuals, and catastrophic surprises that they’ve come to expect as Relic brings the franchise into the modern era."
Dawn of War 3 is expected for release on PC. Neither plans for a release on additional platforms nor a launch date were specified."
Only 3 races: Space Marines, Eldar, Orks. In Dawn of War III you will have no choice but to face your foes when a catastrophic weapon is found on the mysterious world of Acheron.
Heroes Return: Gabriel Angelos (Space Marines), Farseer Macha (Eldar), Gorgutz (Orks)
Big warmachines: Imperial Knight (Space Marine), Gorkanaut (Ork), Wraithknight (Eldar).
One Army to rule: Build your own universal army from the very first moment you are matched in a melee. Progress through battle after battle with loyal troops by your side across both challenging campaign missions and dominating multiplayer maps.
Space Marines, Orks and Eldar. The campaign moves between factions from mission to mission as each army converges on the same planet to retrieve a mysterious weapon. All of the factions have their own collection of heroes, elites, super units and super abilities that you develop over the course of the story. Gabriel Angelos returns to lead the Blood Ravens, and he'll tee off against an Eldar Farseer and an Ork Warlord.
Bases are back!
