Batman: Arkham Asylum is finished and the demo is up on PSN and Xbox Live. I was pretty much responsible for the PS3 version on the engineering side so anything wrong with it is ultimately my fault.

This one popped up pretty quickly after the demo was released:

The article is quite accurate (unlike some of the comments) and it was generally very positive which is great to see as we put a lot of effort into getting parity between the two console versions.

The game has been getting a good reception which is especially nice given that Batman games have a long tradition of being terrible.
