A ruse is a deception, an action or plan which is intended to deceive someone, for example a ruse of war.

R.U.S.E. is a real-time strategy video game developed by Eugen Systems and published by Ubisoft which was released for Microsoft Windows, PlayStation 3, and Xbox 360, in September 2010. The game was subsequently released for Mac OS through Steam on 15 November 2011. R.U.S.E. is a strategic war game set during World War II and focuses on the invasion of Nazi Germany during late 1945. The campaign includes many historical and some fictional events. It focuses on information warfare instead of a brute-force approach. Players can use a series of ruses and decoys to trick their enemies and change the outcome of the battles. However, the outcome of the battles in the game also relies quite heavily on how a player manages their economy and which units they use.
