Developer 4A Games has released a series of brief teaser videos showcasing a PlayStation 4 entry in its Metro first-person shooter series running at 60 frames-per-second.

4A confirmed in March that its Metro series would debut for the PlayStation 4 and Xbox One in the upcoming Metro Redux. Fans speculate that today's footage shows both Metro 2033 and its sequel Metro: Last Light running on the same gameplay engine. A third teaser video is available here.

While a release date for Metro Redux has not been announced, comments from 4A suggest that the game may arrive quite soon. "Are you ready?" the developer asks. "Because we really, nearly are..."
