Try to see the link i provided in the thread if the patch is already available for you. I'm already currently downloading it.
Actually I'm gonna download a pirated copy first, to check if the game runs decently on my PC (wish they released a demo). You know, I don't wanna spend my money for nothing. What does the patch do?
The patch unlocks the game. There are some people who got the early copies such as me but it's locked and we can't play it till today.
