About
ActionXL is a video game developer and hardware design group started in 2003 in Ithaca, New York.
The hardware design group uses accelerometer technology to create motion-sensing game controllers for the PC and the DS Motion Card for the Nintendo DS.
The game development studio designs and creates casual games that specifically use the motion-sensing controllers, and also provides a software development kit so that other developers can integrate the controllers into their own games.
