Alien Intruders

This software is a thrilling game that allows you to save your planet from an invasion of hordes of alien intruders from outer space. Your mission is to destroy all of the enemies and bring the invasion to a halt.

At the start of the game, enemy ships will align in 3 rows and gradually move downward while firing randomly. You control your spaceship at the bottom of the screen using the left and right arrow keys on your keyboard, then press Spacebar to shoot.

The game is not easy, with aliens moving faster as some are destroyed. You must also watch out for an alien probe that will appear at the top of the screen; it consumes the last digit of your score, but you can retrieve it by destroying the probe.

To make things more challenging, you start the game with only 3 lives, which are displayed at the top left corner. One life is deducted each time your spaceship is hit. You lose the game when all lives are gone or the aliens reach the bottom of the screen.

In summary, this software provides an exciting gaming experience that requires quick reflexes and strategic thinking to save the day and drive the enemies away.
