Call of Duty: WWII's 4th DLC, "Shadow War" launches today, first on PS4.
Coming with the DLC are three multiplayer maps: Airship, set at a Nazi German air base in the middle of some snowy mountains; Excavation, which takes place in what looks like a mine; Chancellery, which I assume take place at the German Chancellery.
Operation Arcane, the newest mode for War, looks to see Allies protecting against Germans advancing upon a base with a tank in tow.
Rounding out the DLC is Frozen Dawn, the final chapter in Nazi Zombies (at least for this game). Set in a vast underground complex, it looks like a good type of crazy.
