A total of 6 additional games will leave on December 31. The list includes BlazBlue: Cross Tag Battle, Humankind, LEGO 2K Drive, Party Animals, and more. In total, Xbox Game Pass and PC Game Pass will lose 13 games this month. Below is the list of titles leaving at the end of December:

Microsoft announces the first wave of the December 2024 Xbox Game Pass lineup, which includes five new titles and several XGP Standard additions.

Update [Tue 3rd Dec 2024, 6am]: It turns out that just seven games will be leaving Xbox Game Pass in early December rather than the original eight that were reported, as Hello Neighbor 2 is no longer on the list. We also now know what's leaving Xbox Game Pass in late December, as covered elsewhere on Pure Xbox:

All 50 games will be available to stream through any device that has access to the Xbox app with Game Pass, including TVs, smartphones, tablets and PCs (via web browser). Microsoft claims it will bring this feature to Xbox consoles and the Xbox Windows app in 2025.

The Xbox Game Pass content library is losing nine titles today and breaking one unfortunate 2024 record in the process of doing so.

Xbox Game Pass is a subscription service for Xbox consoles and PCs. You pay a monthly fee to subscribe to the service, and in exchange, you can download and play games from the Xbox Game Pass library on your console.
