True classics never die.

Alien Sky is based on the old favourite Space Invaders, but updated to take advantage of better graphics and sound. The action is fast and furious with plenty of different alien spacecraft to defeat.

Even more impressive are the different formations they take – understanding the weaknesses of each is key to succeeding. Enemy ships can also intercept power-ups, adding another level of difficulty to the game.

You can control your space ship with keyboard, mouse or joystick. There is also the possibility to post high scores on the Alien Sky website.

Take a raid deep into alien force positions to eliminate the threat for your homeworld. You'll encounter lots of different alien ships, upgrade your weaponry with extra-weapons, blow up enemy barriers and defeat powerful bosses. Lots of special effects, unique tactics for each level, nice music and sound FX, Worldwide Hall of Fame and much more.
