Calico and LoneStar Were the Final Epic Games Store Mystery Games of the 2026 MEGA Sale

As the Epic Games Store MEGA Sale 2026 enters its final week, one of its most popular attractions has officially wrapped up: the Mystery Games promotion. For three weeks, the storefront teased and revealed pairs of free games, encouraging players to check back every Thursday at 11 AM ET to claim them before they disappeared. The final pair of mystery games, Calico and LoneStar, were revealed on May 28, 2026 .

What Were the Final Mystery Games?

The last two titles to be hidden behind the mystery wrapping paper offered a distinct contrast in style, giving players a relaxed sim and a tense tactical experience.

• Calico, developed by Peachy Keen Games, is a day-in-the-life community sim focused on rebuilding a town's cat café . Players can decorate the café, ride giant cats, and befriend a variety of animals in a whimsical, pastel-colored world. It holds a "very positive" rating from over 2,600 reviews on Steam, with 88% of them being positive .
• LoneStar is a strategic roguelike deckbuilder set in space . Players take on the role of a bounty hunter, customizing their spaceship and engaging in tactical, turn-based battles against outlaws across the galaxy.

Both games were new to the Epic Games Store free game program and had a combined value of approximately $25, with Calico normally priced at $11.99 and LoneStar at $12.99 .

The Claim Window Has Closed

The free offer for Calico and LoneStar expired on June 4, 2026, at 11 AM ET . Since the current date is June 5, 2026, these particular games can no longer be claimed for free, and the Mystery Games portion of the sale is officially over.

What's the Status of the MEGA Sale and Free Games Now?

Though the mystery game reveals are finished, the Epic Games MEGA Sale continues through June 11, 2026, at 11 AM ET, offering discounts of up to 75% on over 2,500 PC games, including major AAA and indie titles .

The weekly free game giveaways haven't stopped. A new pair of non-mystery games, Rogue Waters and Songs of Conquest, became available on June 4 and will remain free to claim until June 11 . These are turn-based strategy titles that are part of the standard weekly free game rotation, not part of the mystery promotion.

How Long Did the Mystery Games Event Run?

The entire Mystery Games promotion ran for exactly three weeks (21 days) . It began on May 14, 2026, with the start of the MEGA Sale, and ended when the claim window for the third and final game pair closed on June 4, 2026 . After this point, the store reverted to its typical practice of announcing the next week's free games explicitly instead of teasing them as mysteries.
