defly.io

Defly.io combines helicopter combat with territory capture on a shared map. Fly with WASD or arrow keys, shoot with the left mouse button, and place walls with right click or Space.

Link towers into closed zones to earn score and XP, then spend levels on aircraft and building upgrades. Your bullets pass through your own walls while enemy shots bounce off them.

Expand carefully, seal areas to level up, and use superpowers to break stalemates. The player who controls the most ground often controls the match.
