The moody, gritty PC/PS3/Xbox 360 shooter Metro: Last Light was supposed to come out in early 2013. Then Metro's publisher, THQ fell apart.
Metro will eventually be released by new publisher Deep Silver. For now, it's still possible to see taxis in Manhattan topped with these ads. Their prominence is fading, as the ads cycle out. But if you look closely, you'll see a THQ logo in the bottom right corner.
I shot this photo last night. It's a vestige of what was in an ad for a game that we'll play who knows when.
