Earth is under a relentless attack by extraterrestrial forces in UFO Defense. These invaders come in two distinct colors, and your survival depends on your ability to react quickly. To destroy an alien, you must use a weapon of the corresponding color. Be careful: hitting an enemy with the wrong color will cause it to grow larger, stronger, and much harder to defeat.
The alien forces attack in increasingly difficult waves. As you progress, the number of attackers grows, testing your reflexes and precision. Your ultimate goal is to survive the onslaught and destroy the massive mother ship that serves as the source of the invasion. Work fast, avoid mistakes, and save our planet from total destruction!
