Master the Mechanics of NOVAGUARD: Sky Defense

Controls are simple but depth comes from how you manage your energy and positioning. You do not need complex buttons to fight this space war. Use these actions to stay alive:

• Tap or click anywhere in the sky the closest battery fires an interceptor to that point
• Hold to charge a bigger blast
• Drag across the sky to raise the Barrier when the overcharge bar is full
• Destroy everything before it reaches the city
• Kills inside trigger chain explosions

Strategy and Upgrades for NOVAGUARD: Sky Defense

Success requires more than just fast tapping. You need to master the chain reaction mechanic. When you destroy an enemy inside an existing explosion, you trigger a new blast. This skill allows you to clear massive waves with a single well-placed shot. As you progress through six sectors, you will face massive bosses like spined alien warships and horned leviathans. Each boss has a pattern. You must hit the exposed core, target the vents when they open, and time your shield usage perfectly. Between runs, use your earned resources to upgrade your batteries. You can choose different upgrade paths to change your playstyle or equip sector modules to alter the rules of the sky.
