Spiral

Spiral is a tier 2 tank that upgrades from Basic.

Design
The Spiral is a kinda hard tank to describe but it looks like it has a wide Swarmer cannon and a Pounder cannon together as one whole cannon.

Technical
The Spiral is a weird tank too. The bullets it shoots just go around the tank! This is kinda good for protection, but kinda bad for long-distance shooting.

Upgrades
The Spiral upgrades from Basic and upgrades into Whirlwind. That's all the upgrades!
