Completely unexpected. Vermintide 2 just released today for $29.99, but you can play it free day one if you have Xbox Game Pass, even though it's not a Microsoft first party title. Awesome for those who took advantage of the recent $5/mo. slick deals. Rocket League is now on Game Pass as well for those who care. Ever since E3, Microsoft has been adding some awesome third party titles to Game Pass. Enjoy.
