Speed Glitch

To perform the speed glitch, start by moving forward (holding W) and then strafe to either side (hold A or D). While strafing, move your camera in the same direction as the strafe to initiate the speed boost.

Once you've turned a certain amount in one direction, you can then turn the opposite way to chain the speed together. Each turn further increases your movement speed. While there doesn't appear to be a limit to how fast you can go, maintaining the chain becomes progressively harder at higher speeds.

It's easier to start the glitch if you have a light weapon equipped, as heavier weapons will slow you down. I recommend practicing with the bow, as it seems to have the lowest movement penalty, making it ideal for learning the trick.
