As reported by engadget,
Google has switched on Stadia in eight more European countries. Residents of Austria, the Czech Republic, Hungary, Poland, Portugal, Romania, Slovakia and Switzerland will be able to start using the game-streaming service over the next day or so as Google rolls out access.
That brings Google’s tally of countries in which Stadia is available to 22. As long as you have a Gmail address and a decent enough internet connection, you’ll be able to play Destiny 2 or Super Bomberman R Online gratis across a number of devices. New members get a free month of Stadia Pro, which includes a number of additional games. Continuing a subscription and maintaining access to games costs €9.99/month in those countries.
