100 Levels of Aerial Combat
Alien Sky Invasion is a top-down aerial shooter with 100 campaign levels. You pilot one of 6 unlockable jet fighters against increasingly large and aggressive alien formations — from small scouts to massive capital ships. Each jet handles differently, and your dual-weapon loadout (primary guns + homing missiles) gives you flexibility in how you tackle each wave.
How to Play
Move your jet with the arrow keys or WASD and fire automatically. Use your gun for rapid suppression and missiles for armored or fast-moving targets. Watch your health bar — enemies fire back, and screen-filling bullet patterns in later levels demand constant movement. Collect power-ups dropped by defeated enemies to boost your firepower temporarily.
Progression Tips
- Prioritize destroying enemy weapon platforms before picking off smaller units.
- Save missiles for bosses at the end of each chapter.
- Unlocking faster jets makes later levels significantly more survivable.
