It cannot upgrade further.

As the Groundwire

 * Although you look like and upgrade from Submachine, your reload is much lower than anything else in its branch. Beware that despite its appearance, this tank is by no means a bullet spammer.
 * Try to use the bubble bullets to your advantage so you can overwhelm others.
 * The bubble bullets have decent penetration and may be able to pierce weaker bullet storms such as those from a Gunner branch.

Against the Groundwire

 * Use fast rammers to juke the small bullets and crush this tank.
 * This tank has poor close range performance. and will likely fall to a dedicated assault.
 * If you want to kill one, try and rush it before it sets up its bubbles and saturates an area with fire.
