Cannon (Tower)

The Cannon tower is an explosion tower, and probably one of the first the player will buy from Global Upgrades for 100 Green Papers. It shoots exploding shells that damage multiple enemies.

Appearance
It is a red pentagon with one of its sides protruding what seems to be a tank barrel. It sits upon a pentagonal base, which it rotates upon.

Strategy
These can be useful, cheaper alternatives to Missile towers in any phase of the game. Their main feature, exploding shells, can be quite handy against clumps of enemies. To use their explosion damage for maximum effect, pair these up with Blast towers. Not only does it cover a big weakness for them (Icy enemy), the blast tower complements them by minimizing the space between enemies, giving Cannons extra damage against these clusters. However, Cannons have one huge flaw: Light enemies. The damage they do against them is pitiful, so it's advised to pick up another tower that can cover this weakness, like a Multishot or Minigun. They also have poor range and RPS compared to others, so it is advised to upgrade these to level 2 or 3 first to cover that weakness, then start buying Damage and Attack Speed. Their poor RPS also limits their effectiveness on corners, where they must cover a wide attack angle; on the other hand, corners are perfect locations for the Blast towers.
