Dead Rising Jumpchain

From the introduction: Welcome to Metport City, once the very embodiment of a West Coast American metropolis. The majority of its citizens have since become infected and it is now overrun with thousands of zombies. On top of that, the infection is due to an evil government plot and they're going to do a bombing run in a week’s time to level the entire city and destroy any evidence and any survivors left in it! You're going to have to deal with zombies, king zombies, gang bangers, looters, psychopaths and the military all as you try to put the pieces together and keep those few sane innocent individuals safe.
