A video demonstration of Halo Wars from TGS has hit GameTrailers, and we think it's fairly safe to say that the game is looking pretty good. Then again, we thought as much when we got a chance to play it at E3, so what would you expect? Nevertheless, the video showcases some things that we didn't see at E3, namely a commander unit, the Vulture "Uber Unit," and a new command ability called the Cryo Bomb which freezes enemy units, giving you extra time to destroy them.
Without a doubt though, the most intriguing part of the video happens right at the end of the demonstration, when we get our first glimpse at the Flood. We only get a general idea of how the Flood base is structured and also a brief look at the Infection Forms as well as what look like (former) human Combat Forms.
Now, if we can just get this time machine working, we can play it right now.
