Call of Duty Black Ops Cold War - Gameplay campaign Mission 8 - Break on Through - Played on PC. Next-Gen Ultra Realistic Graphics [4K UHD]. Break on Through is the eighth campaign mission of Black Ops Cold War, which you will have to play through as many as 4 times. Each playthrough of this mission begins the same way, but will differ later on depending on your decisions. After a failed attempt to retrieve a stolen Greenlight nuclear bomb from Cuba, Russell Adler begins to use psychoactive drugs as a last resort to coax "Bell" into giving up the location of Perseus. Implanting false memories into their mind, Adler attempts to walk "Bell" through several scenarios in Vietnam, in which they must locate a Soviet bunker containing Perseus and his spy ring. At any time, the player may choose to go against Adler's guidance and choose a different path. "Bell" will hear the voice of Perseus before the first scenario, telling them not to trust Adler. The mission consists of open combat and various strange illusions. In this mission you can also get The Red Door achievement, which consists in being disobedient to Adler. It is best to decide on your approach before the mission so that you can either obey or disobey the whole time.
