Metal Gear Solid 4: Guns of the Patriots is the final canonical Metal Gear game to feature Solid Snake as the main character. The gameplay of the previous games have been kept along with some new features, such as the ability to roll on your back and also to hide in bins scattered around the environment. Most of the story and the relationship between the characters are explained through cut-scenes with a considerable length, so knowledge of the prior games is recommended to fully understand the story. The game also features a complex multiplayer mode entitled Metal Gear Online with some original missions based on the stealth aspects of the single-player games.
