The first video trailer for the upcoming Warhammer 40K Online MMO is finally here, released by THQ and Vigil Games today at the E3 Expo in Los Angeles

Fresh from E3 in Los Angeles today, the Warhammmer 40K MMO video trailer is finally here! Announced by THQ and Vigil Games with the official title, "Warhammer 40,000: Dark Millennium Online," the debut trailer only has a running time of one minute, but those 60 seconds are filled with exactly the type of in-game footage and action that fans were hoping to see. We see several different races showcased in the trailer; Imperium (of Man), Chaos and Orks, including an array of different "Chapters" (i.e., the Space Marines and Imperial Guard for the Imperium, and Chaos Space Marines and Cultists for Chaos).

One one hand, we're not sure what to make of THQ's earlier promise that all the Warhammer 40K factions will be playable (we didn't see the Eldar, among other races, in the video), but on the flip-side, the trailer gives us the impression that the upcoming MMO will kick some serious ass. We see both land and air vehicles (possibly indicating the vehicular combat players are hoping for), titans and dreadnoughts stomping across the battlefield, a third-person character view (with what appears to be an ability-based interface) and more. The combat scenes don't confirm or deny the existence of a "cover system" (based on terrain and line-of-sight factors), so we'll have to wait for ZAM's upcoming interview with THQ/Vigil Games at E3 this week to get more answers. In the mean time, check out the video trailer for Warhammer 40K: Dark Millennium Online after the jump!
