Wall Running is a movement mechanic in Call of Duty: Black Ops III. Most flat walls can be run upon. To activate wall running, the player simply jumps towards a runnable surface and they will automatically begin wall running.
There are no weapon restrictions while wall running, and the player may continue to aim and shoot. However, turning too far from the direction they are moving in will cause them to stop running. After a short time wall running, the player will begin to slide downwards and must jump back on the wall to continue running.
