How to use the input buffering technique in Call of Duty 21 Black Ops 6
Input buffering is a technique where you hold down an input while performing another action (usually gliding). The buffered input will fire as soon as your current action completes. All we care about is lining up to slide while jumping. Holding down the slide key while in the air will perform a slide when you land.
You will glide in the direction of your momentum, meaning you can effectively turn around and shoot your target while moving in the opposite direction. Input buffering for skating like this can be very effective on Warzone and larger maps.
