- "Cannon Towers will fight in combat for you, and will protect the buildings they are near. Bristling with cannons, they seem to say - "Oh yeah? Make me...""
- — In-game Description
The Cannon Tower is a cheap, armored defense that can defend against enemy encounters within its defensive range. They can be useful against Riot Troopers in early levels, but their low health means they may be taken out faster than other units.
Building a Cannon Tower is the focus of the mission Metal Tower Intellectual.
