5pb. never ceases to amaze me with the number of associated websites/accounts that they have.
Couple of days ago they pushed an update to Asian copies of Psycho-Pass: Mandatory Happiness on Xbox ONE that added the English localization.
【News】English language patch is now published for "PSYCHO-PASS MANDATORY HAPPINESS" (Xbox One edition, for Asian market).
Thanks XMSHO for the notice.
The game was released in the West for the PS4 and Vita in September, with a PC version slated for 2017.
