Taking into consideration the dark outline around the tank, this also includes the Smasher (a hexagon), the Spike (a 12-pointed star) and the Landmine, (an icositetragon, a 24-sided polygon, in the shape of a 12-pointed star). This also includes Auto Smasher, which looks like a Smasher with an Auto Turret and the Dominator (hexagon).
Cannons can appear in many different shapes, sizes and numbers.
Cannon shape often determines bullet characteristics; wider Cannons shoot larger Bullets, and longer Cannons have faster Bullet Speed.
Normal Bullets, used by most of the tanks, are circular shaped.
Some tanks use Drones or Protectors, which are often triangular shaped, but, in the case of Necromancer, can be square shaped.
All controllable tanks can move their body with the arrow or WASD keys. They can move their Cannon(s), which always points at the cursor, with the mouse. Pressing C will make the tank spin automatically.
To shoot ammunition, a player can press SPACE, or left click with their mouse. Pressing E will enable the tank to fire automatically. However, Smasher and its upgrades (except Auto Smasher) lack the ability to shoot Bullets.
For any tank that utilizes controllable Drones, left-clicking (or SPACEBAR) will bring the Drones towards the mouse cursor. This is always on if Auto Fire is enabled. Right-clicking (or SHIFT) will repel them away from the cursor. Otherwise, the Drones will return to the tank and orbit it, unless there is a Polygon, a Boss or another enemy tank nearby. In the case of you using Factory, your Minions shoot to your cursor when left clicking or Auto Fire is on, and looks away, or if close, gets dragged (only if cursor is close to the Minions|Minion) if right clicking.
Spawning is the act of being born into the arena. It is done by pressing enter on the computer version, or by pressing the green arrow button below the player's name, in the mobile version. A player will always spawn as a basic Tank. The player will spawn in their base in 2 Teams, 4 Teams, or Domination. In FFA, Survival, Tag, Maze, or Sandbox, the player will spawn at a random point on the map.
When the player spawns, they rotate for a second. Their body also flashes slightly for approximately 15 seconds. During this time the player cannot be harmed. In this time, if they collide with Crashers, Polygons, Bullets, Tanks, or any other entities, the entity will be destroyed, at no health cost to the player. Undisturbed, this period of invincibility lasts for approx. 15 seconds, however if the player moves or fires, then the period is stopped. However, a player select upgrades, or fill in the stat bar during this time. This feature was created to prevent tanks being spawn killed.
The level a tank spawns at is determined by the level it was killed at previously. If this is the first time the server has been joined, then the tank will spawn at level 1. A level 45 tank will spawn at level 22, with a range of values in between. If a player leaves the site, then returns, they will spawn at level 1. The level a player will spawn at is shown below their name.
