Batman: Arkham City gets yet another slate of DLC today. Thankfully, at least some of it is free.

"We have had an amazing release of Batman: Arkham City and we wanted to thank you all for your incredible support before, during and after the game's release," game director Sefton Hill said in a thank you letter to fans. "As a token to our appreciation, we'll be offering a brand new, totally super sweet, Batman Inc. Batsuit skin absolutely free!"

The skin is available as a free download now on Xbox Live Marketplace and Games for Windows. It will be available on PlayStation Network later today.

The PC version gets another bonus as well: the "Challenge Map Pack" is available for free. Everyone else will have to pay $2.99 (240 Microsoft Points) to test drive the new maps. Included in the bundle are three areas: the Batcave, Joker's Carnival, and the Iceberg Lounge.

Finally, there's a discounted "Arkham Bundle" for those of you that have yet to jump into any of the game's DLC offerings. For $14.99 (1200 MSP), you'll be able to get a discounted bundle which includes Nightwing, Robin, and the Arkham City skins pack. Combined, the three go for $18.97 (1520 MSP).
