Basic

The basic is a tier 1 tank that upgrades from nothing and has many upgrades.

History:
This tank has existed since the release of the game.

Design:
This tank has a singular, unedited cannon in the front.

The cannon shoots decent bullets with medium penetration and damage at an average rate.

Technical:
This tank is the tank everyone spawns as, the basic can upgrade into more advanced classes like the Twin or Sniper.

As The Basic:
Keep away from bullet spammers as they will quickly out-penetrate you with their bullets.

Try using a lot of movement speed to shoot down classes with lower reload like the Destroyer branch.

U can try going after Director branch classes but you will most likely die unless you are skilled.

Against The Basic:
Use a bullet spammer with high movement speed to chase down the basic, try to corner it so you can kill it easier.

Try using Director branch, charge your drones directly at the basic, try to keep yourself shielded while attacking the basic and you should do just fine.

Trivia:
In diep.io the basic is just called "Tank".
