After reading this I headed on over to the Rockstar Vienna website but it appears it is down at the moment, so I'm not sure what's going on there.
This morning, as I came into work, I was greeted by security guards. It turned out Take-Two has closed their Rockstar Vienna office, effective immediately, "due to the challenging environment facing the video game business and our Company during this platform transition".
For those of you who don't know, Rockstar Vienna worked on the the Max Payne series, as well as the Xbox versions of GTA3 and Vice City.
Rockstar Vienna's closure leaves over 100 developers without a job.
