Phantom Crash is set in a derelict Tokyo a couple of decades from now, the entire city abandoned due to pollution and overheating and everyone moved, in true anime tradition, to the artificial island of Neo Tokyo. But while the government was happy to leave the old city to collapse in its own time, a new sport called Rumbling is hurrying things along. Put simply, it involves dropping several heavily armed mechas into Old Tokyo and leaving them to blow each other (and their surroundings) to smithereens. The result is fast-paced and anarchic, with the vehicles charging around the streets of the Shinjuku district blazing away with heavy machineguns and pounding each other with rapid-firing missile launchers.
