The fastest way to earn experience points is to focus on completing missions rather than just surviving, since mission objectives reward bonus XP on top of what you earn from defeating enemies. Make sure to collect all items dropped by alien enemies, as rare alien technology can be crafted into better gear that makes tackling harder missions easier.

Special attacks are powerful abilities that can clear entire screens of enemies and are unlocked by leveling up your character and investing skill points into your chosen abilities. As you progress through missions, you will gain access to increasingly devastating options, so experimenting with different skill builds is key to finding a playstyle that works for you.

Alien Sky Invasion features a variety of sci-fi environments including crashed motherships and alien-controlled cities, each with their own unique enemies and boss encounters. The missions become increasingly challenging as you advance, keeping the gameplay fresh and rewarding throughout your playthrough.
