Earlier this week, PC gamer revealed an interview, as well as some new gameplay while they were talking. The next day, they released a full uninterrupted 60 minutes of gameplay. And the day after that, they released a (very) short video showing a KF2 match on the Hell on Earth difficulty. There was a lot of hype this week, and that led everyone to believe that the game would release this week.

However, an email was posted on Reddit that said they were looking for GSPs and people that would be willing to host servers so they could watch server stability, performance and all that good stuff. This email was posted about 19 hours ago now.

But just now, I was looking on Steam and noticed that KF2 has been released, but doesn't have a price tag yet. Is this an April Fool's joke, or a mistake? I don't know, but this is pretty cruel if it's not legit.
