Crouching can make special attacks incapable of connecting, resulting in a whiff.
To whom may read this,
Today I'd like to address an exploit that has been in the game for about 10 months now that is actively being used in public lobbies to gain a competitive advantage. This exploit at hand is called the "Crouch Tech". What a "Crouch Tech" is in basic summary, is crouching our in the open, by a surface of elevation or near a high-collision obstacle to avoid losing a health state via the said special attacks: Lethal rushes (The Blight), Shred Attack (The Demogorgon), Chainsaw sprint (The Hillbilly), Virulent Bound (The Mastermind), and Slice and Dice (The Good Guy).
I don't have clip evidence of The Mastermind or The Good Guy, but in summary I will explain how crouch tech is used and abused against those 2 said killers. Against The Mastermind, you can crouch next to a gap within a pallet or window and it will cause The Mastermind to vault the said pallet or window. Meanwhile, The Good Guy you can crouch next to a collision hitbox area like a locker, pallet or a filler tile/loop/pallet and cause the slice and dice to collide with the environmental hitbox or straight up whiff.
Below clips can be applied to any map in any realm, we just used Autohaven Wrecker's as a vanilla/bread and butter example for the 3 most impacted killer by this said crouch tech exploit.
I'd like this to be investigated as you clearly could not "crouch tech" around 10 months ago and it's been discovered and used ever since.
Please keep in mind these compiled clips are only simple examples replicated for the sake of exposing this crouch tech exploit, and there are more "advanced" techniques and positioning to use this exploit.
Enjoy!
