Metro: Last Light is the sequel to 4a's Metro 2033. It's current release date is some time in 2013. I know that I for one am waiting patiently(well maybe not) to once again explore post apocalyptic Moscow and it's decaying metro system. I have already done a couple post's on the game(one today) and I'm sure I will be doing even more as time roll's on. If you want to look at some more info on the game you can go here or here.
