Call of Duty: Vanguard - Season Two

On Caldera, Captain Butcher and his team uncover Axis intelligence on a chemical weapon called Nebula V. The documents reveal reported locations of the weapon across the island — and a stockpile of it held in a fortified position thousands of meters above sea level in the Swiss Alps. Butcher assembles Task Force Yeti: three specialists in alpine warfare and close-quarters combat. They go in to clear out the remaining Axis forces and retrieve more Nebula V for Allied research. A surviving commander, cornered, shows them firsthand what the weapon does if released. The stakes become immediately clear.
