They are releasing a couple of screenshots every day now... well, almost every day. Anyway, this newest one had the HUD showing and i think it tells us quite a bit about the game. Damage sections, heat management, weapons and radar.... looks like pretty much everything we would expect from a real, hardcore mech game.
it's huge, so rather than stretch the thread all out, I'm just going to link to it.
