Extremely skilled legend big boss doing the worm around an enemy base and noone sees him

Proper dolphin diving DOESN'T use the W movement key- using movement keys lower your camo rating.
You need to alternate between three stances: crouching still, jumping, prone still- and then you repeat.
If you add movement key input, you will get more visible during crouching bit.
You can find the camo factor charts for this game on the internet, people made photos of the physical guide/books from the physical retail versions/collector editions.

it's cuz guards spot you at farther range when prone compared to crouched, this dolphin jump thing makes it so you're only crouching for a few frames of the total animation so it's like you're always prone. I just roll, personally.

i thought this suppose to be the frog jump method or smth like that, but i was dead wrong

being normal is overrated

you can also play the game as a normal human being

Diving on the other hand can be heard at a way shorter distance because the game wants you to use your dive and I think they wanted to give you those close heart racing moments where you use it to quickly get into cover and save yourself from dying or getting seen. Another reason why this is insanely stealthy is because the game's AI NPCs detect you by the size you are from their angle and how fast you're moving, this is why crawling slowly is the best form of stealth because you're way shorter, you blend into grass, you're covered by a lot of objects, you're way slower, and lastly you make a little amount of noise.

Forgot to mention I think I might know how it works, I'm a little newer to the game(170 hours) so take this with a grain of salt. I think when you aim and change your stance you change your stance faster than you would do so while not aiming because the game wants to make it easier to shoot over or under objects where you're being shot from and your gun is being blocked, hence the reason why they give you the faster stance change because when you're getting shot at you can die pretty fast. So the reason why you can dive instantly is because the game wants you to be able to change your stance faster but because this was likely added in later after play testing they couldn't give it a whole new animation and allowed weird bugs like this to happen. The reason why your so sneaky while doing it is because you can be heard at a distance of 15 meters while running without a sneak suit and an even closer distance while not using a sneaking suit which is around 11 meters.

lmfao I might be late but that comment about sportsmanship is a joke, why would someone not used something that would put them at an advantage if they could, if it's such a big problem then they should just fix it.

when you're releasing the aim button it somehow makes game think the standing animation is canceled which allows you to dive instantly
