Metro 2033 takes a different tack from all of the movie-to-game tie-ins by actually being a book-to-game tie-in instead. Now, you might think that's no different, but it really is. The only visual cues developers have to go on is the imagination of the reader, and the mind of the author. Luckily, Kiev-based studio 4A has Russian writer Dmitry Glukhovsky to help make Metro 2033 a visual reality, coupled with the developer's talent for generating some fantastic graphics out of a PC setup. Dmitry Glukhovsky's urban tale takes place in a post-apocalyptic Moscow, where the capital's Metro train line becomes the only safe haven for humanity. With the world destroyed by an apocalyptic event, the surface of the Earth becomes uninhabitable, and those who dare to go outside must face deadly sunlight, a lack of oxygen and mutated creatures that lurk in the darkness. Presented as a first person shooter, with a hint of underground town exploration, Metro 2033 adds some interesting elements to the genre, including a reduction of the HUD and a reliance on visual cues to survive topside. Bullets double as both your ammo and as currency for purchasing better weapons. If you want a shooting game that's out of the ordinary, with an RPG element that adds depth to the firefights, Metro 2033 is worth checking out.
