This sequel took the original's concepts took to somewhere amazing.

Revamped Graphics and Gunplay make this post apocalypse game amazing.

Surprisingly great story with great gunplay. Dual wield some rocket launchers and kill those nazi bastards.

Classic arena shooter that made FPS important and is still fun to this day.

Cold War Era is better cool.

Great game with huge learning curve. May not be everyone's cup of tea but it's free so why not give it a try.

A competitive game with elements of Jet Set Radio, Smash Bros, and Pong

Like Borderlands with more guns and better story

Like Skyrim with guns

One of the greatest stealth games of all time
