In celebration of upcoming Radio Flare Redux game, the developer of the original Radio Flare is offering the game for free this weekend. More about Radio Flare:
Radio Flare is a music shoot'em up for the iPhone and iPod Touch.
Propelled by radio flares, your space ship speeds pulsing though deep space, taking you on a journey through music and space at the same time. Radio Flare invites you to experience a beautifully modeled space trip accompanied by an interactive electronica soundtrack.
