Co-op doesn’t get more suave than Warframe, with its slick sci-fi environments and eyeless, knob-faced title characters. We originally reviewed the MMO shooter back in April; it had just been let off the leash into the world of open beta, and despite the associated growing pains, we felt it was a strong concept with room to grow further. Seven months have passed now, and the steady content stream has beefed up Warframe considerably.
