Sunset Overdrive is a 2014 action-adventure video game developed by Insomniac Games and published by Microsoft Studios. The game is set in 2027, in a fictional metropolis called Sunset City. The player controls an employee of FizzCo, who has to fight off the OD, short for Overcharge Drinkers: humans who have turned into mutants after drinking FizzCo's energy drink beverage. In the dystopian Sunset City, the player character can wall-run, use zip-lines, and grind rails to swiftly navigate through it, with a large arsenal of weapons to use. The game also has a cooperative multiplayer mode called Chaos Squad, which tasks players to complete a series of missions with seven players. As the game puts emphasis on momentum, the game does not feature any cover system.
