Pretty good price for two great games.
You get Batman: Arkham Knight and as a "free gift" you will also get Batman: Arkham Asylum GOTY.
So for very little money you get many hours of entertainment.
Alternatively, you can get Batman: Arkham City and Batman: Arkham Asylum GOTY for $6.88 AUD: https://www.greenmangaming.com/games/batman-arkham-city-game...
From the website:
In the explosive finale to the Arkham series, Batman faces the ultimate threat against the city he is sworn to protect. The Scarecrow returns to unite an impressive roster of super villains, including Penguin, Two-Face and Harley Quinn, to destroy The Dark Knight forever. Batman: Arkham Knight introduces Rocksteady's uniquely designed version of the Batmobile, which is drivable for the first time in the franchise. The addition of this legendary vehicle, combined with the acclaimed gameplay of the Batman Arkham series, offers gamers the ultimate and complete Batman experience as they tear through the streets and soar across the skyline of the entirety of Gotham City. Be The Batman.
The Bat is back! Batman: Arkham Knight arrives as one of the top PC games of the summer! The journey that started with Batman: Arkham Asylum and continued through Batman: Arkham City approaches an epic finale as the Caped Crusader faces off against The Scarecrow, Penguin, Harley Quinn, and the eponymous, mysterious Arkham Knight himself. But this time, Batman won't be fighting alone.
We're excited to team up with the likes of Azrael, Oracle, and Nightwing but perhaps most thrillingly of all, now we get to take the Batmobile for a spin! We can't wait to get behind the wheel and start chasing down thugs on Gotham's streets, before transforming into a bat-tastic tank and unleashing some serious explosive justice. Arkham Knight is shaping up to be the most ambitious game Rocksteady have attempted, and it has all of the tools to live up to the hype.
