DISCLAIMER, PLEASE READ BEFORE ENTERING: This is actually a key for the base game, more specifically, the open beta for it. This game isn't in open beta anymore, and is free2play. I have no idea what will happen when you activate it, though I assume you'll just have a free game locked to your account for no reason. If it doesn't work, I'm sorry, I just wanted to get rid of this key tbh. Please don't complain to me if it doesn't work.

TL;DR: This key is for the base game when it wasn't F2P. It is now F2P. This may or may not work, don't complain if it doesn't.
