Check out over nine minutes of the Freerun mode in Call of Duty: Black Ops 3.
There are currently four stages: Beginner, Intermediate, Advanced and Expert, and each become pretty tricky near the end. They serve a purpose though as each act as a tutorial for the new movement abilities in Black Ops 3.
Plus, if you're feeling competitive, each successful completion will be posted on leaderboards along with the time completed.
Call of Duty: Black Ops 3 is out tomorrow, November 6 on PC, PlayStation 4, and Xbox One as well as PS3 and Xbox 360.
