does anyone know if you can have more than one mgs4 online account on a single ps3 via different ps3 profile because i want my brothers to play online too but when installing it it said something like you can only have one and you have to pay for a second one .......i'm realy confused

yeah, you can only have one free character slot on your PS3, if you want another you have to buy it online which is a pain in the ass because the konami shop is fucked up :/
