Rockstar Vienna is best known for producing Xbox versions of the Max Payne and Grand Theft Auto games. A former member of staff contacted us with news of the closure earlier, and it was also reported by designer Jurie Horneman in a blog post. HERE
"This morning, as I came into work, I was greeted by security guards," Horneman wrote.
"It turned out Take-Two has closed their Rockstar Vienna office, effectively immediately, 'due to the challenging environment facing the videogame business and our company during this platform transition.'"

This morning, a Rockstar spokesperson told us: "Yes, we can confirm the studio was closed on Thursday."
"Employees will be offered packages in accordance with Austrian law, as well as other job opportunities within Take-Two and Rockstar Games where possible."
