Superhero Hype reports that Warner Bros. Interactive Entertainment and DC Entertainment have announced the season pass and a premium edition for Batman: Arkham Knight. Both the season pass and premium edition are available for preorder at participating retailers. The season pass is $39.99 and the Premium Edition (with the season pass and main game) is $99.99.

The season pass will deliver new content for six months after the game’s launch including new story missions, additional super-villains, legendary Batmobile skins, advanced challenge maps, alternative character skins and new drivable race tracks. The game will be released on June 23 for the Playstation 4, Xbox One and PC.

Here’s a synopsis: 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.

40 bucks for DLC is a joke, that's essentially the price of a full game.

FORTY FUCKING DOLLARS? That's 2/3rds the cost of the game, I doubt I'm getting 2/3rds of the game in content.
