Hey mate, if you pre-ordered right underneath where it says Play this game in 21 days, there's a section called "Description" if you pre-ordered it should say this:
Your purchase of Cyberpunk 2077
comes with a Stadia Premiere Edition (free standard shipping). Watch out for an email after the game releases to claim your bonus. Must be 18 years or older, to learn more click
here. Cyberpunk 2077 is an open-world, action-adventure story set in Night City, a megalopolis obsessed with power, glamour and body modification. You play as V, a mercenary outlaw going after a one-of-a-kind implant that is the key to immortality. You can customize your character’s cyberware, skillset and playstyle, and explore a vast city where the choices you make shape the story and the world around you.
Hope that helps!
