The Batman Arkham Collection, which includes Arkham Asylum, Arkham City and Arkham Knight, is free to download for users, as well as Lego titles Lego Batman and its two sequels.
Epic has also confirmed that the next free games on the store will be Metro 2033 Redux and Everything, which will be available from September 26.
Epic originally launched a bi-monthly free game offer alongside its PC storefront in December 2018 but said in mid-May that it was increasing the frequency of the offer to one free game per week until the end of 2019.
Titles offered for free have included Alan Wake, For Honor, Limbo, This War of Mine, Overcooked, World of Goo, Transistor, The Witness, Hyper Light Drifter, Fez, Inside and Celeste.
After missing targeted launch dates for several new features, Epic recently removed anticipated delivery times from the Epic Games store roadmap, which provides a public overview of what’s being worked on or planned.
The Epic Games store’s August update introduced cloud saves for more titles and Humble Bundle keyless integration, while giving product pages a facelift.
