Thief: Deadly Shadows is probably one of the best parts in the series.
There is no Russian localization in the game, but there are amateur translations for the game. The plot is simply simple, without any unnecessary complications. The game implements something like factions that you need to please, there are small quests that change your reputation and relationships with factions.
The game has a complex but fascinating plot, and the musical accompaniment is simply superb.
if you haven’t played this game then my advice to you is just try it and you won’t regret it. The game has at least 2 scary levels: the ship "9 shaft" and the mental hospital "Moira"
