Why Once Human can trigger motion sickness

First person puts the camera at eye level, so melee swings and weapon movement move the whole view. The developer wrote that continuous multi-hit attacks caused significant shaking of the camera and actions, which can easily lead to discomfort, and it redesigned melee for first person. Third-person play is still there, and on PC Alt+C switches views.

  • First-person melee and weapon movement, where the whole view moves with each action
  • Screen shake feedback on hits and weapon fire
  • Weapon camera shake in first-person and over-the-shoulder views

Frequently asked questions
