NOVAGUARD is a one-finger air defense shooter. Tap anywhere in the sky and your batteries detonate an interceptor right there: no aiming stick, no buttons. Meteors, swarms, armoured hulks and drifting mines rain down on the last city. Every kill inside an explosion sets off another, so a well-placed shot can chain a dozen targets in a single wave of fire. SIX SECTORS, SIX BOSSES. From a spined alien warship to a horned leviathan, each boss has its own trick: hit the exposed core, then the vents when they open, then chain a kill inside the shield. BUILD YOUR DEFENSE. Upgrade your batteries between runs, choose upgrade paths that change how you play, and pick sector modules that change the rules of the sky. COME BACK EVERY DAY.
