On the first Tuesday of each month, Sony makes a new set of games available for free to PlayStation Plus members. We've passed that milestone for December, which means the month's free PS4, PS3, and PS Vita games are now available. Add them to your library, and they'll be yours to download and play as long as you have an active PS Plus subscription. You can get all of the free games right here.

On PS4 this month, you can grab Soma, a game that's decidedly not filled with holiday spirit. In this atmospheric horror game, you're tasked with exploring a seemingly deserted underwater facility to discover what happened to the human and AI occupants. The other PS4 freebie is Onrush, an off-road online racing game that's more about takedowns and teamwork than about finishing first.

On PS3 this month, you can grab Steredenn: Classic, a pixelated space shooter that mixes retro-arcade action with procedurally generated levels and massive boss fights. The other PS3 freebie is SteinsGate, an anime-style visual novel about teenage scientists who discover a way to send messages to the past--which you can bet begin to affect the future.

This month's PS Vita games are the customs agent sim Papers, Please and the Metroidvania-style side-scroller Iconoclasts, the latter of which is also playable on PS4 thanks to Cross-Buy. Make sure to grab your free games by Tuesday, January 1, because that's when a new batch will come and take their place.
