Warner Bros. seem intent milking their games for every dollar they’re worth through DLC, as evidenced by Mortal Kombat X‘s easy fatalities and shockingly expensive Season Pass, and today they’ve revealed details on the Season Pass for Batman: Arkham Knight.

This DLC pass, which is priced at an eyebrow-raising $39.99, contains additional story content, and, most notably, the ability to play as Batgirl in her own prequel story, set in a new location. The full details are as follows:

Batgirl: A Matter of Family

An all new prequel story expansion in an entirely new location where you play as Batgirl for the very first time in the Arkham series – check out the first render of Batgirl.

The Season of Infamy

Play as Batman in all new story missions featuring legendary super-villains invading Gotham City, with new story arcs, missions and gameplay features.

Gotham City Stories

Play as Batman’s key allies in narrative missions extending their storylines, from both before and after the events in Batman: Arkham Knight.

Legendary Batmobiles with Themed Tracks

Drive the most iconic Batmobiles from Batman’s 75-year history, on custom-built race tracks, each themed to that Batmobile’s specific era. Every Batmobile will be drivable across every race track.

Crimefighter Challenge Maps

Engage in a series of new challenge maps utilizing the unique play styles of Batman and his allies.

Character Skins

A variety of skins from across the eras for Batman, Robin, Nightwing and Catwoman.

The announcement adds that these additions are not a complete representation of what’s inside the Season Pass, and more will be revealed at a later date. Still, do you suppose all this is worth paying $40 extra on top of a $60 game? You’ll have to vote with your wallet when the game is out on June 23.
