Field of View

Field of View (FoV) refers to the distance a tank can see in any direction. Some tanks, such as Quantum Foam and Macaroni, have very small FoV, but other tanks, such as Planer, Warden, and S-Sounder have much higher FoV. Director-branch tanks, as a general rule, have a higher FoV than normal tanks, though Invariant-branch tanks have a lower FoV. Smashers have a slightly increased FoV. For simplicity and lag reduction, tanks have a square FoV rather than an FoV that fits the monitor. Auto turrets have a slightly higher FoV than the tanks they are sitting on.

Mechanics
The FoV of the Basic is 29 grid squares at level 0 and 48 grid squares at level 60. FoV ranges from about 35 grid squares for Macaroni and Quantum Foam to 71 grid squares for Warden, the highest FoV tank. The FoV is calculated using the width of the monitor, and the Basic has 48-square FoV from left to right no matter the monitor shape.

Auto turrets have a slightly higher FoV (approximately 10%) than the tank they are sitting on. AI have a square FoV and attack anything that comes within range, so attacks from the top or bottom are common and can be deadly.

Scoping
All of the Single-branch tank have the scoping ability, which moves the center of the field of view to the edge of the original FoV in the direction the player is facing. The directions can be any of the four corners or sides. The FoV is kept the same, except that it is not connected to the player anymore. As long as right-click, which is the scoping button, is held, the FoV stays in the same place even if the player moves. This can be both dangerous and helpful depending on the situation.
