September 21 marks the 80th anniversary of Batman, and Warner Brothers is making both the Lego Batman and Batman Arkham trilogies free on the Epic Games Store as part of the ongoing Bat-Celebrations. Both Bat-series can be downloaded for free on PC through Epic's storefront until September 26.
The three games included in the Batman Arkham Collection bundle are the main titles from developer Rocksteady Studios: Arkham Asylum, Arkham City, and Arkham Knight. Arkham Asylum recently celebrated its 10-year anniversary—as USgamer's Eric Van Allen points out in his retrospective, the game served as a blueprint for more recent classics like Middle-Earth: Shadow of Mordor and Marvel's Spider-Man. The 2013 prequel entry developed by WB Games Montreal, Batman: Arkham Origins, is not included as part of the collection.
The first three Lego Batman games make up Traveller's Tales trilogy of games, inspired by older Batman media unrelated to Lego itself. The second Lego Batman game, DC Super Heroes, was the first in the developers' series of Lego titles to have fully voiced cutscenes. The third game, Beyond Gotham, was released after 2014's The Lego Movie, but doesn't feature Will Arnett's take on Lego Batman, in case you're wondering. Sorry if that's a bummer.
These Batman titles are part of Epic's ongoing weekly offers of free games through its platform. Recent free titles include Conarium, The End is Nigh, and Abzu. Next week, the available free games will be David O'Reilly's Everything and Metro 2033 Redux, both making their Epic Games Store debuts.
