Duo Defense

Ditch the static towers. Duo Defense delivers active, manual combat. Protect your arena from constant monster attacks by deploying two fighters at the screen boundaries.

Active Survival in Duo Defense

In this fast-paced arcade game, you do not build walls or wait for resources. You actively volley a defensive projectile to smash monsters emerging from the center. As the arena fills with monsters, every volley becomes harder to track. Switch your focus quickly as the enemy waves thicken.

Unlock 100+ Characters 

Collect gold and unlock a massive roster of over 100 playable characters. Snatch Coin Magnets dropped by defeated enemies to automatically gather currency so you can focus entirely on your volleys.
