Cannon Defenses
About Cannon Defenses
You build and merge cannons to hold back wave after wave of enemy troops, tanks, and bosses in Cannon Defenses. Purchase basic turrets and place them along your defensive line, then drag matching cannons together to merge them into higher-tier weapons with greater firepower. Your goal is to stop every attacker before it crosses the bottom boundary—let one through and your defense crumbles.
Eight tiers of upgrades keep the challenge fresh as enemies grow tougher. Early rounds let you experiment with turret placement, but later waves demand smart merging and positioning to survive. Poki Games brings you this tower-defense puzzler that rewards planning as much as quick thinking, pushing you to balance spending, merging, and repositioning until the final boss falls.
