A new trailer for Planetside 2 is in from gamescom, and is designed to get you jacked, amped, etc. for the recently started beta, or alternately, make you cry because you haven't gotten in yet.
I've heard PC Gamer says this one looks as good as Battlefield 3 graphically speaking, but I just can't see it at all; the footage below looks much more akin to Tribes: Ascend (which is decent unto itself but godawful compared to Battlefield 3). Gameplay looks pretty fun, though, if not lacking some polish.
