Invaders - shoot waves of aliens earning as much points as possible. Back in 1978 it swept the world and became a first "killer app" for video game consoles. The game was so successful that in Japan it was attributed to the shortage of 100 yen coins and in 1982 it grossed 3 times more than newly released Start Wars movie. It has been ported to numerous platforms. So why should you give our version a try? We tried to recreate all the fun of the game in a tiny download package. Waves of colorful, funky-looking aliens are descending on Earth, and your mission is shoot them down before they can land. Tilt the phone to move defender ship from side to side, shielding your ship behind the brick-wall defenses. The longer you take to eliminate the aliens, the closer they get to the ground. Shoot down the extraterrestrial spaceship at the top of the screen for extra points. Don't forget to check our Game section for other fun games...

Arachnoids, Attack of the space spiders Thanks for volunteering to save the Earth in this retro arcade space shooter. The Arachnoids are invaders from another galaxy. They have crossed light years of space time in order to claim our most desirable little planet for the Spider Empire. Your job is to defeat the evil space spiders, save the Earth and make the universe a safe place once more. Space spider invaders are the most feared species in the Galaxy, they are not really evil. No, its because they reproduce at a staggering rate, either by spontaneous division or by laying spider eggs which very quick reach full maturity. The inevitable result is a population explosion like nothing on Earth and so the Arachnoids are continuously searching for new planets to colonise. You must stop the Space Spiders before their number grows out of control. Download Arachnoids now and help save the planet.
