The Epic Games Store reached 61 million monthly active users as a result of its game giveaway campaign, “The Vault.”

“The Vault” campaign ran from May 14 through June 18 and included hits like GTA 5, Borderlands: The Handsome Collection, and Civilization 6 that players could download for free and keep forever.

Another milestone that the store reached during the campaign is 13 million average peak concurrent users.

While a massive UA success for Epic, the reported stats still are still much lower that the 23.5 million concurrent users that Steam saw amid the COVID-19 outbreak.
