While Virtual-On Force has not been announced for North America, it is import friendly. Over on the Cyber Troopers Virtual-On Force blog, Murayama from the porting team announced the Xbox 360 game is region free and is translated into English.
Play-Asia confirms this by noting the cheaper Asian region version is region free too.
The news comes to us from Kris who’s daydreaming about a Temjin 707 vs. Temjin 747 battle in class. Thanks to Sega-Addicts and Mecha Damashii for pointing this out!
