Seraphim

The  is a Testbed Misc tank.

Design
The tank has an identical front gun to Basic and 9 Gunner-like guns on the back of it arranged in a roughly triangular formation..

Technical
The front gun works as expected, firing moderate strength bullets at a reasonable pace. The rear barrels fire two at a time going down, before the cycle restarts at the center barrel. These rear barrels fire very fast and have unusual recoil, allowing the tank to go very fast.
