Viginti Tres

 is a Tier 5 Tank that upgrades from Hurricane and Stari at level 60.

Design
The looks identical to Hurricane, but all but one of its guns gain a small Subduer-style barrel inside of them. The barrel without a Subduer barrel is the one that faces the mouse.

Some versions of the game give it this additional barrel, bringing the tank's total to 24 barrels.

Technical
Unique among Subduer branches, the mini-barrels have very low delay compared to the main barrels they are attached to. This makes the tank essentially stack its bullets.

Trivia

 * The name means 23 in Latin.
