You play as Duke Nukem, who is asked to save Earth from an invasion of aliens. You will go through Vegas and other areas in the USA while kicking ass and taking a piss every so often. Duke Nukem Forever is a First Person Shooter with Platforming segments in the game. These segments can be quite tedious as you will be doing these a lot during the main story of the game. Something which Gearbox included in the story was a variety of other things to do, like playing a game of pinball or air hockey. Though they have included a multi-player mode which doesn't add much value to the game.
