Eidos Montreal knows a thing or two about reviving game franchises thanks to the success of Deus Ex: Human Revolution. The studio is currently at work on Thief 4, with general manager Stephane D'Astous saying it is part of the kick-start of new series that Deus Ex began. The challenge with Thief 4 is to strike a balance between the new and the familiar. Eidos Montreal wants the game to appeal to fans and newcomers alike, so the classic gameplay should get a refresher. Thief 4 will be "more than just stealth," however D'Astous did not elaborate further aside from saying more international staff are working on the game. A good mixture of nationalities should help diversify the game, but scant few details are available on just what Thief 4 will bring to the table. Hopefully Eidos Montreal starts showing the game off soon, as it has already been eight years since Thief: Deadly Shadows launched.
