Alright so this game came out last night. It's free on the Japanese PSN Store... It has 14 trophies that you can earn without paying anything, They're all ranking up based except the 3 secret trophies ( Which are... Win your first match, Be praised for the first time & Log on for 7 consecutive days )
This is a good video for making a Japanese PSN account.
This site has a good tutorial for finding the game in the store and a simple understanding of the menus/controls.
Other than what's provided in those 2 sites I'm just kinda wingin it right now, playin the game and earning some free trophies
Feel free to add me if you wanna play PSN: JuggaloMemnoch
