Tom Clancy's EndWar is a strategy video game available on Microsoft Windows and all seventh-generation platforms except the Wii, with the timing and flow of gameplay differing across platforms. The console and PC version is a real-time tactics game designed by Ubisoft Shanghai, while the handheld versions feature turn-based tactics. It was released on Nintendo DS, PlayStation 3, PlayStation Portable, and Xbox 360 in November 2008. A Windows version was released in February 2009.

Real-time tactics (RTT) is a subgenre of tactical wargames played in real-time, simulating the considerations and circumstances of operational warfare and military tactics. It is differentiated from real-time strategy gameplay by the lack of classic resource micromanagement and base or unit building, as well as the greater importance of individual units and a focus on complex battlefield tactics.
