From the developer:
Zombie Biker is a unique game where the city has become an apocalyptic place on earth since the zombies have taken over and you are one of the lucky few not yet infected. Armed with nothing more than a street bike and a bad attitude, you must plow through wave after wave of undead scum to rescue the few remaining survivors.
