The camera will bob around in Senua’s Saga: Hellblade II. To see how you reduce, or completely disable, this movement, you can take a look at this guide at Seeking Tech.
1. Open up Settings from the Pause menu.
2. Next, you need to go to Gameplay.
3. You then need to select Accessibility.
4. You should now see the Camera Bob slider, which is set to 10 by default. Set it to a lower value to reduce the camera movement.
To completely disable it, set the Camera Bob setting to 0.
