The game won't be released until June 30th on PC. Source:
wiki. If the game isn't out yet, it is (usually) a scam.
If the uploader didn't include a password on the download page, it is a scam.
If you have to jump through any hoops (surveys, password pages, referral links, etc) to get your game, it is a scam.
If you get testimonies from YouTube about the authenticity of your download, it is a scam (who does this anyway?)
As joe said, always look for the comments on the page you downloaded from.
In a side note, when picking which file host to buy premium for its generally best to pick the one you see is used most commonly. On the sites I frequent, that tends to be uploaded.to and rapidgator. I'm currently sharing a premium sub with RG with a few friends and splitting the cost.
