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.
