#What is it? The most useful glitch of the whole game, usable in all categories except Glitchless, because it is considered a Major Glitch. Thanks to the Sentry Jump you can reach great heights, much higher than the double jump. It is useful for reaching objects and areas that can only be reached with the wall jump and/or wings. #Where can I use it? You can only use it while touching the ground, so you won't be able to use it while jumping or falling. #How can I use it? To use Sentry Jump first you will need to look up and ALMOST press at the same time the jump and attack (Z and X). But in reality it's not at the same time, in fact you will have to press the jump a couple of frames before the attack. #Examples of Sentry Jump
