Thief, which was originally set to be known as Thief 4, is a reboot of the Thief franchise and is currently in development by Eidos Montreal and is due to be published by Square Enix sometime in 2014 on the PlayStation 4, Microsoft Windows, and Xbox 720. The series' main character, Garrett, has returned to his home to find that it has fallen under the rule of an iron-fisted baron who preaches prosperity for all but in reality power and wealth seem to be gravitating to an elite few. This, however, leaves Garrett with a great opportunity to ply his trade as a thief.
The game will bring back much of the original Thief formula but with a few more modern improvements thrown in. Thief will encourage players to sneak through the game (in a first person perspective) to steal riches without being seen. Garrett will make use of his iconic bow to cover his tracks and trick guards while making use of a new grappling hook for quick getaways and "Focus", which acts similar to Detective Mode or Instinct Mode from the Batman: Arkham series or Hitman: Absolution respectively. This will allow him to move more quickly while pickpocketing or picking locks, find the best hiding places for the best loot, or highlight enemy weakpoints if you find yourself stuck in combat.
