Screen Invaders is the debut game by Attollos Technology and is conceived as very much being a 'pick-up and play' game for the casual gamer community. Set in a world where Earth is on the brink on an impending alien invasion, the user has to navigate their way through dozens of levels, repelling wave after wave of attacks.

Screen Invaders is also an incredibly rich game for the first released version. As the Americans would put it, you get a lot of 'bang for your buck'. Indeed, there is game center integration, multiple difficulties to test your skills against a more stringent clock as well as facebook and twitter integration to challenge your friends to beat your score.

With its tap-based concept, Screen Invaders is very much a universal game that can be played and enjoyed by people of all ages. As the levels increase, more and more monsters appear and the color of the alien indicates how many taps it takes to kill them. The gameplay is also broken up by the availability of 2x, 4x and 6x combos as well as the screen freeze concept introduced to make sure that more accurate players are rewarded better. We hope that the universal nature of this game will ruffle a few feathers at the top level of the App Store, so move over Angry Birds, the invaders are here and "their time is coming".
