Activision has released a new preview video for Call of Duty: WWII's first expansion, Resistance, which launches early next year. In the video, developers from Sledgehammer Games talk about the new multiplayer maps, as well as the next War Mode map and the new Nazi Zombies content. According to Sledghammer boss Michael Condrey, Resistance is the "biggest, most exciting" expansion content that Sledgehammer has ever made.

The expansion includes three new multiplayer maps, Valkyrie, Anthropoid, and Occupation. That last one is a remake of the Modern Warfare 3 map, Resistance. They are all themed around the idea of resistance, Sledgehammer said. For example, Valkyrie takes place near the bunker where the failed real-life mission to kill Hitler, Operation Valkyrie, took place. Anthropoid, meanwhile, is set in occupied Prague during Operation Anthropoid.

As for the new War Mode update, Operation Intercept has players rescuing French resistance fighters and then fighting to escape. The new Nazi Zombies content, meanwhile, is called Darkest Shore. It introduces new, smarter zombies, as well as the "ripsaw" weapon, which is what you get when you combine a buzzsaw and a machine gun.

Also new in Darkest Shore is fog as an environmental effect; this will make it more difficult to see enemies coming your way, which should heighten the intensity, Sledgehammmer said.

Resistance launches on January 30 on PlayStation 4, coming to Xbox One and PC about a month later. It's included with Call of Duty: WWII's $50 Season Pass while it will also be available to by individually, apparently. Three more expansions for Call of Duty: WWII are coming later in 2018, though these have yet to be formally announced.

While you have to wait a while longer to play the new Resistance maps, Call of Duty: WWII is currently hosting a limited-time event called Winter Siege.
