Thief Deadly Shadows was released simultaneously on for PC and Xbox unlike previous games in the series which were PC exclusive. Eidos Interactive, the publisher of Thief games, were able to secure the rights to Thief and eventually assigned the task of developing Deadly Shadows to Ion Storm Austin. However on May 24, 2000, they were forced to close shop due to financial problems. The previous two games in the series – Dark Project and Metal Age – were developed by Looking Glass Studios and were well known for their innovative stealth based gameplay.
