Besides the E3 trailer, XSEED Games uploaded a small bit of gameplay footage of The Legend of Heroes: Trails of Cold Steel, or Sen no Kiseki. The lack of voices is due to not having finished recording the dub and since they opted not to or couldn’t get the license to use the Japanese voices, they had to be omitted. You can watch the clip below.
The Legend of Heroes: Trails of Cold Steel will be released later this year for PlayStation 3 and PlayStation Vita.
