Surge

The Surge is a Tier 4 tank upgrading from the Chiller at level 60.

Design
The Surge has a circular body, with a rectangular barrel protruding from it. The barrel has some darker spots on it.

When charging up for the "special ability", the Surge's barrel changes color.

Technical
The Surge's main bullet has the same bullet stats as that of a Sniper.

When charging up for the "special ability", the Surge cannot fire regular bullets. Charging up takes seconds. The "special ability" bullets can go through  and rocks. They have infinite penetration and move very quickly. The bullet is a long, thin projectile, and upon impact, the player or boss cannot fire for seconds, and also move very slowly during that time.

Upgrades
The Surge upgrades from the Chiller at level 60.

It cannot upgrade any further.

As the Surge

 * One way that Surge excels in Boss Rush is the fact that a team of two Surges can infinitely stop a boss from firing while the other people kill the boss.

Against the Surge

 * Try to use the fact that the Surge cannot fire while charging up to your advantage. Try to deal as much damage as possible within this time.
