new Cannon Shooter About Duo Defense
Two heroes, one lane, endless zombies. Duo Defense turns volley timing into a defense game. Redirect attacks between partners, unlock new duos, and push for a higher score before the horde breaks through. Free in the browser — no download.
Duo Defense: Pass The Hit Back
Success is rhythm. You are not holding one button — you are choosing which hero takes the next hit and when to send it back. Mistimed passes let zombies slip through.
Unlockable duos change reach and tempo. Find a pair that matches your reaction speed before chasing leaderboard scores.
How to defend longer
- Alternate deliberately: Panic switching creates gaps in coverage.
- Learn each duo’s reach: Some pairs cover wide lanes better.
- Watch the lead zombie: The front threat sets your timing window.
- Restart fast: Short rounds make practice cheap.
