Apparently it is built on the Unreal engine (dunno which one), so I find it hard to believe that this is actual game footage. Have a look at the speculated min. requirements here
. I don't see how that hardware can run a game that looks like this.
Did find some other interesting info though:
Hawken to be free-to-play PC game? | xblafans.com
Haken to ship with seven maps and four game modes
Hawken Mech FPS developers confirm "each team can launch a battle ship" | PC Format
Sounds as though it is still a fair way off and could be a bit hit-or-miss at release. Still, an interesting game. I really want to see how it pans out.
