'Call of Duty: WWII' missions have been revealed - including one which sees gamers infiltrate a German base.

Players' characters will be disguised as Nazis in 'The Wolf's Den' mission in the main story, which will see them having to interact with enemy offices and attempt to say and do the right things to avoid suspicion.

In the September issue of Game Informer, it is reported: "This covert operation is a different play experience than the rest of the game and features unique tools and techniques to make it through an engaging, deadly game of cat and mouse."

The setting for the upcoming instalment in the franchise has raised the question of including Nazi iconography in the game, with developers facing a tough choice to both represent the historical period, while also not offending people.

Sledgehammer games boss Michael Condrey said: "It was important for us to balance the authenticity of the game and era, and the dark notes that come with the genocide that the Nazis brought to bear.

"We need to balance and respect that but also recognize this is a piece of entertainment and not dishonor the loss of life that happened there.

"So in the campaign where it's about this rich narrative and this authentic depiction and the darkness that happened there, we included the swastika, but in multiplayer, zombies, and social space it didn't feel appropriate; it didn't feel like it added honor to the cause."
