Steam has dominated the digital PC gaming market for years, and so Epic Games Store has needed to use gimmicks to cut off a slice of the pie. One way that it's accomplished this is through Epic Games Store exclusives, with Epic spending a ton of cash to secure timed-exclusives for the platform. Another way is through giveaways, giving PC gamers free games in exchange for them downloading the Epic Games Store launcher.

The Epic Games Store capped off 2021 with another iteration of its mystery games promotion, giving away 15 free games from December 16 to December 30. Each free game was teased with Christmas wrapping paper that hinted at its identity before it was officially revealed. Epic Games Store users had 24 hours to claim each of the free games once they were added to the lineup, with the exception of the final free game, Tomb Raider Trilogy, which is free to claim until Thursday, June 6 at 10:00am CT.

The first Epic Games Store mystery game was Shenmue 3, setting the tone that the free mystery games would generally be higher profile games than Epic usually gives away with its weekly free games. That held true for the most part and even included one of 2021's highest-rated indie releases, Loop Hero, on December 20.

Epic Games saved the biggest games for last with the 2017 Prey reboot given away for free on December 25 and then Control released for free on December 26. And of course, Tomb Raider Trilogy was free to Epic Games Store users on December 30.

With Tomb Raider Trilogy, the Epic Games Store is moving away from its free mystery games promotion and starting to go back to its usual routine of giving away a new free game every week. Things are getting back to normal with the Epic Games Store free game for June 6 to June 13, which is Gods Will Fall.
