Ubisoft Japan going to held the For Honor alpha test on PlayStation 4 between October 20 and 24, 2016.
Ubisoft first planned to allow to play with the alpha test version only for the PlayStation Plus members but now this lifted the ban and the non PlayStation Plus users also can try it between October 20 and 24.
But the credit card condition still true. Since the Alpha Test version also got CERO Z rating the player must be 18 year old or older. If you want to test it you have to add your credit card to the PSN and when you download the Alpha Test version the system going to charge 100 Yen fee what you will get back after the test.
