 Thief II received positive reviews from critics , and its initial sales were stronger than those of its predecessor . However , the game 's royalties were processed slowly , which compounded Looking Glass 's financial troubles . As a result , the company closed in May 2000 , with plans for Thief III cancelled . The third game in the series , entitled Thief : Deadly Shadows , was developed by Ion Storm and published by Eidos in 2004 . Thief 2X : Shadows of the Metal Age , a widely praised expansion mod for Thief II , was released in 2005 . In 2013 , Eidos Montreal announced a reboot of the series ( Thief ) , and it was released the following year .
