A new trailer from Metro 2033 is now available on GameVideos, showing off the "kill or be killed" environment in the upcoming post-apocalyptic shooter that, in fairness, is the doctrine in about every FPS ever made. Also, the Metro 2033 team tweets about how the game will not feature a prerelease demo: "lots of questions about a Metro 2033 demo - there won't be one pre-release, we simply don't have time."
