Gunner

The Gunner is a Tier 3 tank that upgrades from the Machine Gun. It replaces its large trapezoid barrel with four small barrels. It upgrades at level 45 into Auto Gunner, Gunner Trapper, or Streamliner.

Design
The Gunner has a circular body with four small barrels. The side two are a bit shorter and twice as thin as the main middle barrels.

Technical
It has the second smallest Bullets in the game (the Flanger's back bullets are smaller). The Gunner's Bullet Damage and Bullet Penetration are decreased but Bullet Speed increases a good amount. Reload is also increased significantly.

As the Gunner
With high Bullet Speed and Reload, players can create hard-to-escape bullet storms that can overwhelm and destroy enemy tanks with ease. This is especially good against slow shooting tanks, as they can't properly counter the Gunner's bullets. This tank can be good against fast tanks as well because it can be hard for them to dodge large amounts of fast bullets. It is highly recommended for Gunner players to invest Skill Points into Bullet Damage and Bullet Penetration, as the base Reload and Bullet Speed stats are immense. Another good strategy with the Gunner is to aim in a spot about 15 degrees higher than the spot you want to hit and press C. Then wait 2-5 secs (depending on the spread you'd like to create) and press C twice (Do not move the cursor during the proccess). Repeat. This will create a wave of bullets, damaging anything and anyone in the spread area. This works with almost all classes, (except for Drone and Trap classes) but it is more effective with the Gunner.

Against the Gunner
The Gunner can be easily destroyed by other tanks with a constant rate of fire (even a Twin will do), as its base Bullet Damage and Bullet Penetration are the lowest in the game. The Gunner's Reload can help counter some bullets, but the Gunner generally can't counter Sniper bullets, so using Sniper classes against the Gunner is a good strategy.

Trivia

 * Until July 31st 2016, the Gunner was the only Tier 3 tank in Diep.io without an upgrade, but on August 1st 2016, the Gunner received its first upgrade, the Auto Gunner.
 * Later that day, the Gunner Trapper was also made an upgrade to it.
 * A few hours after the Streamliner was released, it was also made a Gunner upgrade.
