Epic Games is giving away six Batman games for free right now on its Epic Games store. Rocksteady’s Batman: Arkham Collection and Traveller’s Tales’ Lego Batman Trilogy are both up for grabs and should make nice additions to your games library.Batman: Arkham Collection combines all three Rocksteady Batman Arkham games into a single package. Arkham Asylum, Arkham City, and Arkham Knight can all be picked up in this collection. Batman: Arkham Origins is not included in this collection, possibly because it was developed by Warner Bros. Montreal instead of Rocksteady. Check out our Batman: Arkham Knight below.

Similarly, the Lego Batman Trilogy includes Lego Batman, Lego Batman 2: DC Super Heroes, and Lego Batman 3: Beyond Gotham. Each of those games combines action-adventure gameplay with the recognizable aesthetic of Lego minifigs.

The Batman games will be free only for a limited time, so swoop in now if you want to keep the Batman games in your library.

While the Lego Batman games certainly have their unique brand of family-friendly charm, the standout titles in this Batman giveaway are no doubt Batman: Arkham Asylum

and Batman: Arkham City. Released in 2009 and 2011 respectively, the two Batman games are considered two of the best modern superhero games.

Batman: Arkham Knight was also positively received, but there were known issues with the PC port during its original launch in 2015.

Coincidentally, it’s been rumored that a Batman crossover event is coming soon to Fortnite thanks to files uncovered by data miners. So, it is just a little bit suspicious that Epic Games is giving away free Batman games this week. Is this Epic prepping Fortnite players for some Batman ahead of a limited-time event? Who knows.
