Developer Relic and publisher Sega will release Warhammer 40,000: Dawn of War III, the latest game in the sci-fi RTS series, sometime in 2017 for Windows PCs.

Today's announcement comes with a cool looking cinematic trailer showing Space Marines, Eldar and Orks engaged in massive battles on an unnamed planet. Relic and Sega have yet to reveal any gameplay from Dawn of War III, but based on statements from the game's website, players will be able to control the huge battle units that are showcased in the trailer.

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. With war raging and the planet under siege by the armies of greedy Ork warlord Gorgutz, ambitious Eldar seer Macha, and mighty Space Marine commander Gabriel Angelos, supremacy must ultimately be suspended for survival.

Take control of towering war machines and tip the balance of battle in your favor with the biggest characters in Dawn of War history. Prepare for more epic action as you wage war with massive armies across landscapes full of volcanic terrain or on battlecruisers in space. This universe has no heroes or villains. Through alternating missions you'll soon learn the combat advantages of Space Marines, Orks, and Eldar.

Hopefully we will see actual gameplay in the near future, but based on the descriptions, it looks like Dawn of War III will be a massive RTS game.
