Game overview

Shooting Cannon: Merge Defense is a 3D tower defense game where you combine identical cannons into powerful turrets. Three same-level cannons merge into a higher-tier weapon. Enemies arrive in continuous waves with growing difficulty, so efficient merging and smart placement are essential.

Best suited to players who enjoy tower defense with a merge-puzzle twist.
