Cannon

=Description=
 * Cannon is a conventional tower dealing moderate damage at an alterable rate, it's capable of taking out most kinds of enemies.
 * Each rank reached visually grants the tower an additional barrel, has its damage boosted but fire rate decreased. At rank 1, it is fast and weak, while at rank 3, it is slow and strong. A combination of rank 1 and rank 3 Cannons can take care of almost any enemy type. However, Cannon is generally considered as not the ideal tower for the heaviest nor the lightest enemies, and is often replaced by other specified late-game towers.
 * Usually the Focus and other towers are preferred. In comparison, the unassisted Focus tower is likely to do overall ~30% more damage per resource compared to an unassisted Cannon when both towers meet gfull utility of their range without obstructions. However, the Focus needs warming-up and is hard to call better when burst damage is needed. Mutators, jumpers and fast enemies feel somewhat better with cannon(s). On the other side, the assisted Focus (via Range tower, Slow fields/Kairos, Mind control spire or else) can overcomes this.

=Gameplay Note=
 * Cannon is the first tower available to the player.
