About Alien Space Invasion
It is a straight arcade shooter built around one ship and a lot of incoming aliens.
To survive, you have to clear every alien wave. Each new wave brings different alien threats, so the game asks more of you the longer you last. Your aim matters too, because hitting an alien right in its center earns more points.
Key features
- You defend Earth from waves of attacking aliens.
- Your ship moves left and right and fires with one key.
- Every new wave adds new alien challenges.
- Hits to the center of an alien give a higher score.
Tips & tricks
- Line up with the middle of an alien before you fire, so each hit counts for the bigger score.
