Space Invaders Infinity Gene is a shoot 'em up game released as part of the Space Invaders franchise. The game blends the series classic characters and gameplay with the concept of evolution. The game was developed by Taito and distributed by Square Enix. The game was released for iOS on July 27 2009 after first appearing on Japanese mobile phones and was later released for Xbox Live Arcade and PlayStation Network in September 2010 and for Android in September 2011. The game begins with the classic appearance of the original Space Invaders. However this soon gives way to Charles Darwin's theory of evolution setting the tone for the remainder of the game. At the start of the game the ship features the general controls of being able to move left and right and shoot. However by progressing through the game and earning 'genes' the game goes through evolution introducing new aspects such as being able to move the ship in all directions. As the game progresses evolutions unlock various features such as new weapon types an increased life limit as well as unlockable music and bonus stages. During the game players can shoot down UFOs to release DNA which when collected increases the effectiveness of their selected weapon. The DNA will scatter if the player loses a life. Players can chain enemy kills to increase their score and also perform 'Nagoya Attacks' in which the player can pass through certain enemy fire the moment it is launched.
