I love Gearbox and have been one of their most steadfast defenders over the years, but this looks really generic. The weapons take up too much screen space and the FOV looks awful (both are problems that Brother's Arms: Hell's Highway had as well), and the guns don't seem to pack any real punch.
My biggest gripe - based solely off the footage we've seen - is that the combat with aliens doesn't look all that special. Sure they can climb walls and things...but we've seen countless aliens do that in countless vdeo games before. Even in that clip, isntead of "HOLY SHIT ALIENS", they just sort of appear like "Hey, aliens, I guess that's kinda weird. Whatever, no big deal."
I don't dislike everything though, visually I think the game looks great; the atmosphere and lighting match the movies perfectly. The voice-acting sounds pretty good too, which is actually something I don't think Gearbox gets enough credit for. Their VO is always top-shelf.
