The crouch key in Frigid Dusk on Roblox appears to be C on PC, based on community reports and general Roblox control guides. Some players also report crouch being tied to Left Ctrl in related control menus, so if C does not work, that is the next key to try.

What to try

  • Press C while in active gameplay.
  • If that does nothing, try Left Ctrl.
  • Make sure you are not in a lobby or menu screen, since crouch may only work during gameplay.

Quick note

Different Roblox experiences can remap controls, so the exact key can vary by game even when the default is similar.

TL;DR

For Frigid Dusk Roblox , start with C ; if that fails, try Left Ctrl.
