15. Metro: Last Light
Developer: 4A Games
Set in post-apocaliptic Russia, it's up to you to defend mankind from the Nazi Reich. While most gamers would agree that the story telling can be slow at times, it still doesn't take away from the beautiful disaster of Metro: Last Light. Developers 4A Games did a top-notch job creating the despair of roaming a nuclear wasteland where if the mutated wildlife doesn't do you in, the radioactive environment will. There's so much to worry aboutâ€”from splashing around in contaminated water to breathing in the putrid air. Not since Fallout 3 have we been so immersed in such a desperate position to stay alive.
