If you want to be a part of the Mythos Beta, you can grab a Beta key over at buffed.de, they're giving away 750 keys. It's a little bit tricky, but this is how you can participate in the contest: Register an account at buffed.de by clicking at "Registrieren" in the upper right corner. It's completely free. After that, you have to go to www.buffed.de/go/mythos to create a Mythos account. Then you can login at buffed.de with your newly created account and press the link "Verlosungs-Link" in the list at the end of the news. A popup will appear, where you can click on "Beta-Key anfordern". All keys will be distributed on Monday, so you just need a little luck.
