This week’s issue of Famitsu lists other vehicles you can use to fend of zombies including tanks, armored cars, and bulldozers. Yakuza of the End has its share of wacky weapons too like a fire extinguisher and pitching machine.
If you want to seriously maim some zombies have Goro Majima pick up a chainsaw, rail gun or flamethrower. Those are just some of the weapons in the game. Each character also has their own type of gun or gun arm.
