Proton

The Proton is a tier 4 tank that upgrades from the Revolutionist at level 45.

Design
The Proton has a black ring around it with 3 black balls distributed around the ring evenly. The Proton has a basic barrel.

Technical
The Proton’s barrel is identical to the Basic. Its ring has 3 balls that orbit around it clockwise. The balls act as shields, deflecting most projectiles.

Upgrades
The Proton upgrades from the Revolutionist. It upgrades into the following:

As the Proton

 * As you have 3 shields, you can survive a bit longer than normal. The shields are capable of blocking some bullets.
 * Be wary of drones, swarms, and homing bullets. They can get through the large gaps between the shields.

Against the Proton

 * Use drones, swarms, homing bullets, or just some bullet spammer, like the Twinceptionist.
 * You can outpenetrate the bullets that the proton shoots.
