Here is their announcement on Twitter:

@hexage Radiant Defense has been announced today on @PocketGamer Available soon on #Android #iOS #OSX #WindowPhone #webOS


Intro video:

In the comments, they say the game will be free but with in-app purchase for additional weapons and tactical options. And it's already submitted to the App Catalog for the Touchpad!

Who is excited!! I know I'm very. Just love their graphic designs and commitment to webOS.
