Warner Bros. Interactive Entertainment has announced details of the Batman: Arkham Knight Season Pass. Coming in at a wallet-shredding £32.99 ($50), the Season Pass promises to pack in six months worth of post-launch content.

To put that into perspective, Battlefield 4’s Premium Pass is a little more expensive at £39.99, as is Call of Duty: Advanced Warfare’s £34.99 Season Pass. In terms of single-player games however, the Batman: Arkham Knight Season Pass is easily the most expensive we’ve seen, and is almost double the price the base game can be pre-ordered for over on Nuuvem at the moment.

In terms of what Batman: Arkham Knight’s Season Pass will contain, Rocksteady will be creating new story missions, legendary Batmobile skins, challenge maps, additional character skins, more super-villains invading Gotham City, and even new driveable race tracks for the Batmobile. We didn’t know there was anything like that in there to begin with, so this is an interesting detail.

The Batman: Arkham Knight Season Pass will be available to purchase for £32.99, or included as part of the Arkham Knight Premium Edition. That Premium Edition will set you back an eye-watering £87.98 for the complete version on PS4 and Xbox One, or £67.98 on PC.

In addition there's also the previously announced pre-order bonus guff already detailed. Placing your money down ahead of launch will net you a playable Harley Quinn across a series of challenge maps set in the Blüdhaven Police Department, while the PlayStation 4 will be getting exclusive Scarecrow Nightmare missions. Phew, it's like Watch Dogs' launch all over again isn't it?
