Koei Tecmo today announced that Warriors All-Stars, in Japan released as Musou Stars, is heading to the west on PS4 and digitally on PC via Steam. The PS Vita version will be skipped and won’t be localized for the west.
Koei Tecmo has given no reason why the PS Vita version gets no western release. We only can assume that either the game runs too bad on the PS Vita or Koei Tecmo has given up on localization PS Vita games in the west.
If you still want to play the PS Vita version, you can order the Japanese version of Musou Stars from the online retailer Play-Asia.com.
Musou Stars was released for the PS Vita and PS4 in Japan on March 30, 2017.
