Plot

In 2027, FizzCo has released their new hit energy drink, OverCharge Delirium XT. The only problem is that it’s caused everyone who drank it to turn into mutants. A FizzCo employee teams with the survivors (who are not enemies) to escape.





Gameplay

Players navigate the open world metropolis Sunset City in 2027. The dystopian world is controlled by the corporation FizzCo. The player character, whose gender, skin tone and body type can be customized, is a FizzCo employee, tasked with cleaning up the mess left behind from a party FizzCo has thrown in celebration of the launch of their new energy drink, Overcharge Delirium XT. Players fight the OD'd humans who have mutated from drinking too much of the energy drink.

The game focuses on "agile combat", including wall running, zip-lines, and acrobatics. Players use grind rails to deftly navigate city streets. On-foot, players cannot run or take cover, but instead must rely on agility to survive. Players can carry up to eight weapons at once, including the standard assault rifle and the TNTeddy grenade launcher that fires teddy bears strapped to sticks of dynamite. All weapons eventually run out of ammunition, but do not need to be reloaded while being used. Players unlock more weapons by progressing through the story or purchasing them from shops. Weapons can be upgraded by applying "Amps" that increase their lethality. The Style Meter in the head-up display (HUD) increases as players perform stylish moves like pulling off headshots and grinding on-rails without touching the ground.

In the online co-op mode ChaosSquad, up to eight players defend vats of Overcharge Delirium XT from waves of OD'd. Although they work together, players also try to earn more Style points during play than their co-op partners. However, the game would not support free roam co-op at launch, but could be added to the game through a post-release expansion.
