The superhero fighting game Injustice: Gods Among Us appears to be heading for the Vita. The German USK ratings board has listed the game for Sony's handheld, adding more weight to the possibility of a port.

The USK rating noted by Siliconera doesn't share many details, but this isn't the first we've heard of a Vita version. Months ago, PlayStation Lifestyle (via Joystiq) reported that online retailer Amazon France had briefly listed the game. In that listing, it slated a November release date.

NetherRealm's Mortal Kombat reboot was released in April of 2011, and the Vita version wasn't announced until nine months later. Injustice was similarly released in April. If a Vita version follows the same trend, a formal announcement may come around January.
