Before I list this weeks games that come included with the Stadia Pro subscription, a general reminder how it works: Stadia Pro is the paid service of Stadia, which includes games you can claim as part of the subscription and after claiming play as long as you are subscribed. That is in difference to Stadia Basic, which is free but doesn't offer free games as part of the subscription. In both Basic and Pro you can pay for games in the full catalogue to play them unlimited (even without subscription).
With that said, the six new games included starting December are:
- Into the Breach
- Hitman 2
- Kine
- Monster Jam Steel Titans
- Everspace
- Secret Neighbor
Until November 30th you have the last chance to claim Superhot, Power Rangers: Battle for the Grid, Little Nightmares, Hello Neighbor and Super Bomberman R Online.
The following games will still be available through December:
- Sniper Elite 4
- Risk of Rain 2
- The Gardens Between
- Hello Neighbor: Hide & Seek
- Republique
- Sundered: Eldritch Edition
- Hitman - The Complete First Season
