Fighter

The Fighter is a tier 4 tank branching from the Tri-Angle and Steamboat at level 45. The Fighter-based branch focuses on flank coverage.

History
The Fighter exists in Diep.io, Arras.io, and Woomy-Arras.io making it a very popular tank. On 2 December 2019, the Fighter's front bullet was slightly buffed.

Design
The Fighter has 5 barrels. One barrel points forward, two slightly weaker barrels point to the sides at 90 degrees angles to the front barrel, and two weak barrels positioned at 150 degrees from the front barrel.

Technical
The Fighter's front bullet deals the most damage, while the rear bullets do the least. The side barrels are excellent for area coverage and control, dealing enough damage and having enough penetration to deter opponents. The rear barrels help boost the Fighter forward faster than the Tri-Angle but slower than the Booster.

As the Fighter

 * Pass by enemies to hit them with your new side barrels.
 * Upgrade Movement Speed and Max Health, since you might be under heavy fire while fighting.
 * Go for distracted tanks or tanks without a lot of bullets.

Against the Fighter

 * Use bullet spammers to block Fighter's bullets and deter it.
 * When using a drone tank, keep your drones close by.
 * In Maze gamemodes, one-shot tanks like Destroyer (Tank) are better.
