When it comes to PlayStation Plus, Sony sticks to a pretty predictable pattern. The first Tuesday of each month is when the new free PlayStation Plus games are added to the service, with those games being revealed the previous Wednesday, usually the last Wednesday of the month. When it comes to the free PS Plus games for December 2021, the announcement will likely come on Wednesday, December 1, with the free games added on Tuesday, December 7.
Considering this, it will be about two weeks before PS Plus subscribers have a firm idea of what to expect from the service. However, PS Plus subscribers have been able to predict free PS Plus games in advance thanks to patterns Sony has established with the games. Besides the dates in which Sony reveals free PS Plus games, it has also established a pattern with the kinds of games it includes with the service.
Since the launch of the PlayStation 5, the free PS Plus games lineup has almost always consisted of two free PS4 games and one free PS5 game, and with only a couple of exceptions, the PS5 games have been brand new PS5 releases. This fact has helped PS Plus subscribers narrow down the free PS5 PS Plus games ahead of time, and it's possible that they may have figured out December 2021's free PS5 PS Plus offering.
Heavenly Bodies is a new game releasing for PC, PS4, and PS5 on December 7, the day that the new PS Plus games will be coming out. It's currently the only new PS5 game scheduled to release on December 7, not counting the Final Fantasy 14: Endwalker expansion, though that's highly unlikely to be the free game. This could very well mean that Heavenly Bodies is the free PS5 PS Plus game, but fans should wait for an official announcement.
This method has proven reliable when it comes to predicting free PS5 PS Plus games in the past, like with Hell Let Loose, but it's also been inaccurate at times, like when Sony decides to have an older game as the free PS5 PS Plus offering instead. It's entirely possible that Sony will put up an older PS5 game on December 7 instead of Heavenly Bodies, and so subscribers should keep that in mind. Heavenly Bodies is merely a possibility when it comes to the free PS Plus games for December 2021, and it's far from being confirmed.
Fans will find out for sure in a couple of weeks, and in the meantime, they can claim the free PS Plus games for November 2021, which include three bonus VR games in celebration of the PlayStation VR's five year anniversary.
