Oxyrrhexis

The  is a tier 5 tank that upgrades from the Annihilator, Cartridge, Bumper, Harp, Oxyrrhynchium and Swamper (Oxyrex) at level 60.

Design
The has a rectangular "barrel" the size of the tank in the front that looks similar to Annihilator's. On the end of the rectangle sits a trapezoid, with the shorter side connected to the rectangle. The trapezoid looks similar to the one on the end of Cartridge's barrel but is slightly wider than the rectangular barrel.

On the opposite side is a pink or green triangle, depending on the bullet / missile shot. The missile is a triangle, with a trapezoidal swarm drone spawner. If the bullet is poison, the swarm drones and the bullet turn light green. The normal missiles resemble Guardian and the poison missiles resemble PS3_33.

Technical
The fires one homing missile (that is the Guardian), which also spawns swarm drones.

It can change the rear triangle's color by holding Right-Click, for 4-8 seconds (depending on the reload stat). While under effect of this, it can shoot out the Green Guardians, with the poison effect included. It lasts for 2 seconds.

As the

 * As a Destroyer branch, your bullets deal a lot of damage. Try to go vertically to surprise attack people. Your bullets also are heatseeking bullets, so aim doesn't matter that much, although it helps a lot.
 * Your swarm drones can deal deadly damage at close range, but because a swarm drone's speed isn't very high, at farther ranges, they cannot kill retreating players unless Override is on. They can also deal damage if a player goes in the path of the swarm drones.
 * Override-On bullets travel linearly and astoundingly fast, MUCH faster than homing bullets. Use them during your vertical ambushes when you have a general idea of where the enemy is.
 * Holding right click for some time will allow to shoot a green bullet. This can be used to stack two bullets to deal high damage and penetration.

Against the

 * Be careful of its damage. The bullet doesn't have as much damage and penetration and health as normal destroyer branch tanks, so you can attempt to outpenetrate bullets as defense.(Due to the high amount of nerfs)
 * Watch your flank! users may use Override On to have their bullets fire fast and linear and try to vertical ambush you like a Destroyer. Try to move left or right of the bullets when they fire them at you.
 * As a destroyer branch, is vulnerable to snipers. Try to snipe it and dodge its bullets.
