Fanon:Curvestack

The Curvestack is a Tier 3 tank that upgrades from the Spinner at level 30. It can further upgrade into the Megastack or the Gargantua Idea by Diepmon.

Design
The Curvestack has its barrels arranged like the Spinner's, except in each of the barrels there is a smaller one sticking out like a Hunter's.

Technical
The firing is simple, really: Instead of firing in a normal DNA pattern, the helix pattern is a bit wider and the bullets alternate between Gunner and Auto Turret-sized bullets.
