You have no guns here, just the power to bend a falling missile's trajectory into a miss.
Protect your cities by dragging incoming missiles to redraw their paths, steering them off-screen, into the ground, or into one another. Survive every wave with at least one city left.
The situation is Missile Command's: objects falling toward something you must protect, and not enough of you to go around.
The original departure is that you have no guns. Nothing is destroyed — you bend a falling missile's trajectory until it misses.
That replaces interception with deflection, and it is a different kind of thinking. Shooting something down is a timing problem; nudging it off course is a geometry problem, solved earlier in the fall and with less margin the longer you wait.
Aegis Arc reinvents the missile-defense genre by deflecting threats instead of shooting them. It is an original free browser game built in-house for PlayPendium.
