Rockstar Vienna (formerly neo Software Produktions GmbH) was a Vienna-based developer of computer and video games, and a sub-division of Rockstar Games. Rockstar Vienna was founded on January 4, 1993, joined Take-Two Interactive in February 2001, and was announced to join Rockstar Games during the tenth anniversary of the company in 2003. As of 2005, the company claimed to employ an estimated 100 people.
Prior to the 2003 acquisition of the company, Rockstar Vienna had developed several personal computer games: Whale's Voyage (1993), Der Clou! (1994), Rent-a-Hero (1999), Alien Nations (2000) and The Sting! (2001).
Recent releases include console ports of titles developed by other subsidiaries of Rockstar Games, including Max Payne for the Xbox (2001), Max Payne 2 for the PlayStation 2 and Xbox (2003), and Grand Theft Auto: Double Pack (containing Grand Theft Auto III and Grand Theft Auto: Vice City) for the Xbox (2003).
On May 11, 2006, Take-Two Interactive closed their Rockstar Vienna office without any previous announcement, and employees were denied access to their workplace by security personnel in the morning. This is a rather unusual procedure for closing a company in Austria and considered rude in Europe.
