The Interior of Arkham Asylum was the main level I worked on for Lego Batman 2. I Also worked on a bunch of other odds and sods for the game, including the exterior of Arkham. I might get some screenshots of that if I can be bothered. Modeling, texturing, lighting, and the majority of effects, etc were all created by me.
1up.com said in a preview:
"...this installment in the series is by far the best looking. Particularly gorgeous was the Arkham Asylum portion of the demo. The infamous prison was slowly sinking into the bay off of Gotham City, which made for some great moments of nature bursting through the walls. Having to slog through torrents of water while navigating the halls of the prison provided the most impressive visuals the series has ever seen."
