Thief is an addictive and entertaining one person shooter game in which your purpose is to shoot the thieves without giving any damage to the citizens. All of the people in the building just open their windows for only few seconds. In that few second you should understand that the people on the window are a target or not.

You can get some point if you shoot the thief. You have only five lives and if you shoot someone -for example a citizen- else you lose one of lives. You should not shoot any close windows.
