NOVAGUARD: Sky Defense

NOVAGUARD: Sky Defense puts you in command of the last city's air defense against an alien invasion. The sky is filled with falling meteors, swarming alien ships, armored hulks, and drifting mines. With a simple tap, you can set off an interceptor at any point. The unique chain reaction means each enemy destroyed inside an explosion can trigger more deaths, making a single well-placed shot clear huge portions of the sky. The game features six sectors and six epic bosses, each with special patterns that require you to target exposed cores, vents, or other weak spots. Between missions, you can upgrade your batteries, choose different upgrade paths, and select sector modules that change the behavior of the entire battlefield. A global daily challenge, weekly contracts, and shareable chain cards create long-term goals. Available in seven languages, works on desktop and mobile.

Your goal is to stop every threat before it reaches the city. Tap or click anywhere on the screen: the nearest battery will fire an interceptor to that point. When the interceptor detonates, any enemy caught in the blast is destroyed; and because every kill causes its own explosion, a single well-aimed tap can chain through a whole wave. Hold down to charge a more powerful blast. When the overcharge bar fills, drag across the sky to raise a temporary barrier that blocks projectiles and enemies. Each sector has its own enemy patterns, and boss fights may require you to wait for weak points like an exposed core or open vents before striking. Master the chain timing, choose smart upgrades, and you’ll be able to handle even the biggest alien hulks.
