An enemy spaceship filled with hostile green aliens has landed on Earth. As part of an elite combat unit, your mission is clear: eliminate every monster and reclaim our planet. One Man Invasion features 21 levels of increasing difficulty that will test your aim and logic.
You are equipped with a limited number of shots per stage. To earn a perfect 3-star rating, you must clear the level efficiently. Can you collect all 63 stars and save the world? Sometimes, a direct shot isn't possible; you'll need to master the art of bouncing bullets off metal poles and surfaces to reach hidden enemies.
Mastering the ricochet is the key to success in later stages. Pay close attention to the angles of the environment to make every bullet count toward your 3-star goal. Each level challenges you to think before you fire, blending action with puzzle-solving elements.
The game features a total of 21 levels, each increasing in difficulty as you progress.
To get 3 stars, you must eliminate all aliens using a limited number of shots. The fewer shots you use, the higher your rating.
