The mutants in Metro 2033 were objectionable enough, but the guys that really took the biscuit were those underground Nazis, who appear to have returned in full force for Metro: Last Light. The following trailer shows a terrifyingly well-equipped subterranean army training for war - presumably a war against returning hero Artyom, and his plucky chums from the Metro 2033 station. Last Light, you'll remember, is out this May, so old Arty doesn't have much time to prepare.
Here's the trailer. After you're done, be sure to check out our recent preview (opens in new tab) .
