Rose

The  is a Testbed Overdone tank.

Design
The tank looks like a Basic with a thinner, longer, Pentagon-colored decorative barrel layered over it. In other words, it looks like the Cycloid but its white decorative barrel is made purple. It also looks identical to and.

Technical
Like other members of the Cycloid branch, the fires a particular shape of bullets. Rather than Cycloid's plain circle though, the fires a five-way symmetric formation of bullets that resembles a rose. This formation is composed of many more bullets than any other Cycloid-branch tank, making it considerably more powerful. This may have been the reason it does not branch from Cycloid and was instead relegated to Testbed Overdone.
