Warner Bros. has announced that it will give free digital copies of Batman: Arkham Asylum GOTY, Batman: Arkham City GOTY, Batman: Arkham Origins, and Batman: Arkham Origins Blackgate to anyone who buys Batman: Arkham Knight on PC before November 16th.
The free games will be offered to everyone who has already purchased the game on the platform, and will be in their Steam libraries by the end of November.
Warner Bros. says the free games are a "show of our appreciation" for fans who have been affected by the game's serious issues on PC, which ultimately led to the game being removed from Steam for several months.
Developer Rocksteady will also create a new 'Community Challenge Pack', which will be given to everyone on PC and console for free in January. The pack will be available a week early on PC.
In addition, a Team Fortress 2 cosmetic items pack designed by the community and inspired by Batman: Arkham will also be made available.
