For those who bought the physical copy I believe the code will come with the game's package. I got digital version on PS store, so all those codes were already "installed" via PSN on my PS3, but a friend of mine bought the physical one on PlayAsia and decided to email them about the codes. PlayAsia replied that the there were codes for Early Access, but that the actual game's key only comes with the game itself, so my friend will have to wait for his physical copy to get the code
