An investigative forum user over at NeoGAF has uncovered some interesting information about Eidos Montreal's upcoming addition to the Thief franchise, Thief 4 (or Thi4f... as it's sometimes called in geek speak). According to the resumes of a few outspoken Eidos employees, the stealth game will feature some kind of online mode and will also utilize the popular Unreal Engine 3.Unfortunately, no more information is forthcoming. The so-called "online" mode, which is mentioned in this particular Eidos employee's linkedin profile , could conceivably be a multiplayer mode... but it could also be something entirely different.As for the game's graphical engine, a few employees mention "working with the Unreal-Engine" while developing Thief 4. This is the same engine that has been used to power Batman: Arkham City and Mass Effect 3, among others.Thief 4 was originally announced in May 2009, but since then we have heard next to nothing about its development, much to the chagrin of Thief fans (like myself).The last Thief game to be released was Thief: Deadly Shadows in 2004. As yet, no game in the series has ever featured a multiplayer component... although a fan-made multiplayer mod for Thief 2 does exist.Thanks, NeoGAF
