Epic Games is adding third-party games to its mobile app store and helping developers cover associated iOS fees. The company is launching a free games program and will cover the cost for all titles from developers that participate in the program on iOS or iPadOS devices.

With this program, Epic will roll out new free games in its store each month. The games will be available worldwide on Android and in the European Union on iOS.

The company’s mobile store launched in August with its own titles, including Fortnite and Rocket League. With this expansion, Epic Games is adding the first batch of mobile games from outside developers.

Epic CEO and founder Tim Sweeney says the company has invested more than $1 billion in its digital storefront.
