On the maps that contain bodies of water you will be able to swim and use your weapons underwater. You will not be able to breath underwater so if you need to reach the surface quickly before you die from drowning you will need to use a 'Thrust Jump'.
To begin wallrunning you just run towards a wall and then press 'Forawrd' to continue. When you are wallrunning you can still use your weapons and equipment.
When you encounter low obstacles while sprinting press 'Jump' while near it to mantle. You can mantle in all directions so there is no need to stop moving.
An effective tactic that allows you to shoot from the hip while sprinting is to use the Gung-Ho perk in a custom loadout.
