Return to Castle Wolfenstein

Return to Castle Wolfenstein is a 2001 first-person shooter (FPS) set during World War II. It's the fifth game released in the series, but while it's primarily an FPS like its two immediate predecessors, stealth is often an option (and sometimes the only option) to complete missions, more like the first two games in the series.

Story
It's 1943 and B.J. Blazkowicz, a US Army Ranger assigned to the Office of Secret Actions (OSA), is captured while investigating the activities of the Nazi SS Paranormal Division. After escaping and fighting his way to freedom with the assistance of the German resistance, his mission broadens to include the SS Special Projects Division as well, and he must thwart Nazi efforts to use twisted science and the occult to turn the tide of the war in their favor.
