6. Metro 2033
Metro 2033 was one of them games that come along every so often and shake up the FPS genre- in all the right ways. It was set in a post-apocalyptic Moscow- where everyone now has to live in the vast underground metro system. Ammo is rare and pre-apocalypse bullets are used as money too, though the metro inhabitants make lower grade ammo to avoid you shooting your money away. Certain sections took you above ground too, were you could only survive as long as your gas mask could hold out..making running away the more feasible option.
