Bad Day L.A. will plunge the player into a deep and comedic storyline that plays off the "fear culture" of modern America with a tongue-in-cheek comedic twist. Set in modern-day Los Angeles, Bad Day L.A. will satirize the City of Angels and disaster films while combining a fantastical art style, groundbreaking collaborative gameplay elements and a heavy dose of dark satire to create a truly unforgettable experience.

In Bad Day L.A., players are thrust behind the shopping cart of a homeless man turned city-saving crusader, Anthony Williams, a reluctant hero who left behind the privileged life of a successful Hollywood agent after losing his self-respect. Anthony survives in his cocoon of destitution and isolation in Los Angeles until it all suddenly goes downhill and Los Angeles comes under attack from zombies, terrorists, earthquakes and other untold disasters. Facing complete annihilation, Anthony is reluctantly forced to begin a cynical quest for salvation. Using only his street smarts and the environment to stay alive, he must save the very city he loathes and its citizens whom he detests, and, in the end, escape what has become a very Bad Day in L.A.

Bad Day L.A. will feature ten expansive game levels based on real-world Los Angeles neighborhoods, including Hollywood Boulevard, Venice Beach and Beverly Hills, and each will provide gamers with different challenges and experiences. To fight their way through this battered Los Angeles, players will be armed with an eclectic mix of everyday armaments and bizarre and humorous weaponry, from the mundane firearm to the more improvisational spray paint can flamethrower.
