Add ducking

[sullen tide]

Ducking wouldnt be necessary given the walls you can take cover with are usually the size of if not bigger than the player
also dashing exists if you are concerned about dodging or avoiding

Ducking would only be useful if enemies aim at your head.

They do not. They aim at your middle. You'd get hit regardless.

In my opinion the Dash is a good enough mechanic to avoid projectiles hitting you at large scale.
If you are low on shield or health, retreat and cover yourself on a wall or go to the previous room you've cleared to recover

Add ducking so you can crouch spam like people do in minecraft

Snipers aim at head

So much reasons not to add the basic survival tool...
Like you want to use brick instead of hammer to hammerimg nails.

The snipers in this game doesn't aim at your head, just as Altanna said, they aim at your torso, what causes the damage is their damage output

And to avoid their bullet is walking and going to any wall

[nova sphinx]

Even if that's true, you're looking at 3, technically 4, enemies in the entire game that ducking would be useful against.

And those same enemies have the hilarious weakness of... the player merely sidestepping, the bullet missing completely.
