Limited Run Games currently has “Fu'un Super Combo” for PS4 up for sale. The release features Kizuna Encounter and Savage Reign. They have a standard and collectors edition. I guess the standard is $30 (plus shipping) while the collectors edition is $60 (plus shipping). I grabbed a standard edition.
