Post apocalyptic Moscow is looking better than ever. The whole setting of the game is in Moscow's metro system underground. With the nuclear fallout in the surface, mostly everybody is now living in the metro, trying to survive with mutants and other factions in the metro. It's dark and scary, and most of the time you only see your flashlight as you go around the Metro. Another FPS that I just can't wait to get my hands on. Here's part 1 and part 2 of the E3 demo if you missed it.
If you want a good old classic FPS title that focuses only on the single player, you should try out the first game, Metro 2033. It will give you a better understanding about what Last Light is all about, plus It's just a great shooter that gave me that old Doom feel.
Metro: Last Light will be out next year 2012, no release date yet.
