Fanon:Impactor

The Impactor is a tank that upgrades from the and from the  at level 70. It doesn't upgrade any further, as it is the end of its branch.

Design
The Impactor has 2 longer sidewalls connected by 9 segments, all of this being connected to the main circular body.

Technical
The Impactor has a higher Bullet Speed (Ranger Bullet Speed) and can 1-shot glass cannons (or 2-shot rammers). This comes at a cost of a 5-second reload.

From the Railgun, it gains 3 segments and a longer sidewall.

From The Ranger, its barrel gets transformed into a 9-segment Railgun.

Trivia
I chose the name "Impactor" because actual railguns become more damaging with speed.
