Zombie Driver has got 5 different weapons. One is not a weapon, just an item that boosts your speed.

Machine gun

It is very basic but useful weapon at the beginning while the zombies are not strong. It shoots a string of bullets. What else would machine gun do?

Nitro

It is not exactly a weapon but it does help. It boosts your car’s speed so you can drive faster though it does not help when you get in horde. I don’t personally use this item.

Flamethrower

The best weapon in Zombie Driver in my opinion. It is really good. It just enough to hit zombies with the flame and they eventually die as they burn to death. The better flamethrower upgrade the further the fire goes and more capacity you get. So upgrade it until the best and burn the zombies.

Rockets

I don’t see the point of rockets in this game. You shoot and they explode and kill a few zombies surrounding by a few feet radius but still, you get just 8 rockets and when you miss which is easily done, you don’t kill anyone … though it is better killing hordes I guess …

Railgun

It is an average weapon in my opinion. It is good because it has got a long string of rail which will continue killing zombies from the bottom of your screen right to the top of your screen and if you keep driving that string will kill all zombies it touches. It is good but flamethrower is better in my opinion.

This is it. I mentioned all 5 weapons/items in the game.
