Never heard of it. What's the background of the game?
Metro: 2033 is one of those moody Russian horror/survival shooters that came out in 2010. I picked up a copy for fro about $6, and it’s a very good deal for that. The theme is that after a devastating nuclear war in 2012, the last known groups of humanity are those who happened to be in the Moscow Metro system. A system that also doubled as one of the largest Cold War era bomb shelters.
It’s actually very, very well done. Some genuinely scary moments in it. Highly recommended, especially for the price. If THQ, the game developer company, survives its financial woes, they plan to release Metro: Last Light this March. I think I’ll buy it.
