Alien Intruders is modeled on classic spaceship shooting games and is one of the best arcade-style alien shooting games the Learn4Good Games team has encountered. In this newly revamped game, you control a space ship and your task is to protect the Galaxy from alien space invaders. The alien spaceships will shoot at you back and will keep coming closer to you while moving from side to side faster and faster to have you miss them. If you shoot at the alien Mothership (protected by a team of smaller spaceships), it will drop some valuable weaponry which you have to collect with your spaceship. Your weaponry will be temporarily upgraded by giving you extreme shooting capabilities. Weapon upgrade is not time-based but instead is limited by the number of shots. Once the limit is reached – your regular weaponry is enabled.
How to Play: Use the Left and Right arrow keys on your computer keyboard to move over and back across the game screen. Use Spacebar to shoot. Using your regular weaponry, destroy as many alien spaceships as you can from either of the sides and the middle of the fleet before the Big Mothership appears behind (above) them, while at the same time avoiding their shots. Once you see the Big Mothership coming, forget the small ships and shoot at the big spaceship as soon as you can to save precious time. Once you have shot down the mothership, watch for the colored box being dropped. Collect it with your spaceship. Once you have collected it, get back to firing at the small spaceships, and shoot them all in one go. Try to eliminate all of them before they get too low and start moving too fast. Ironically, the most important point is to be eliminated at the right time to keep your highscore. If you are not eliminated at the right time, you may only get 10% of the score you achieved because the last zero will be eaten away at a certain point. Good luck brave fighter pilot – Defender of the Galaxy!
