An early prototype of the unreleased Batman: Arkham Asylum for the Nintendo DS, by Full Fat. It was to be published by Eidos Interactive.

This version has a build date of 2007.


  • This prototype only has two levels - a rooftop and the library.
  • The music used for this build is almost certainly a placeholder, the track is Largo from Violin Concerto "Spring / La Primavera" in E major, Op. 8 No. 1 - Vivaldi. The track in game appears to be slowed down to around 0.75 the speed of the original composition.
