That is stupidly amazing.
The Batman: Arkham series of games is one of the best things to have happened last generation, and also one of the best and most consistent IPs on the market. Asylum raised the bar on what a licensed game could be like, and was the first instance of players getting to actually feel like what being Batman must be, and Arkham City might legitimately be one of the best games ever made.
Now, both of those, plus Arkham Origins, and all the accompanying DLC for all three games, can be yours for just $10, courtesy Bundle Stars. The bundle includes Batman: Arkham Asylum, Batman: Arkham City, Batman: Arkham Origins, Batman: Arkham Origins: Season Pass, Batman: Arkham Origins: Black Mask Challenge Pack, and Batman: Arkham Origins: Online Supply Drop 1.
That is… stupidly amazing. It might even be better than any deal you can find at a Steam sale, really.
You have about three days to go grab yourself all the games at highway robbery prices, so get on it!
