Nice trailer there!
The good: Lots of things exploding and shattering, nice lighting effects and overall look to it are shown off well here, more things exploding, fast pace, robots with lasers.
The not as good: The jumping looks a little awkward in some spots; combination of the camera angles and some of the screwiness of those two test maps. It'll get ironed out, I'm sure, but it does look a little weird in the trailer.
The hilarious: You (I assume it's you playing) getting blasted a lot by that accursed turret in the labs. Yeah, that one. Devious, that thing. Took me ages to find the way to get at it properly.
Cant wait to mess with that editor. That and seeing what other robot types you have in store here.
