20th July Plot
The fifth mission, titled "Guess Who's Coming Tonight", takes place five days before the attempted assassination of Adolf Hitler in Rastenburg, East Prussia (today Kętrzyn, Poland). The photograph seen in the briefing, where Hitler is shaking hands with general Karl Bodenschatz, was taken on the same day (in reality) when the game's mission takes place in, 15 July 1944. While the mentioned assassination attempt and the character of loyalist colonel Von Below are real, Von Below's first name is Wilhelm in the game, while his real name was Nicolaus. His capture by commandos is completely fictional, as his real-world counterpart remained in service until the end of the war.
Initially planned as an add-on to Commandos: Behind Enemy Lines
, Commandos: Beyond the Call of Duty
was eventually released as a mid-price stand-alone version.
