We will soon be opening up a testing server to select players. The testing server will be a place where players can play upcoming content and provide feedback to developers. We will also be creating a new board for discussing content in testing.
Please keep an eye out on the forums for more details shortly. The first wave of testers will be able to experience Lockdown before anyone else. They will even be able to go toe-to-toe with the dev team. This will be happening very soon, so watch the forums!
