So there is a mod on Nexus that relies on Cheat Engine to allow players to shoulder swap the camera like in previous games
Enable Camera Shoulder Switch at Hitman 3 Nexus - Mods and community (nexusmods.com)
The issue is that it relies on a program I do not trust (Cheat Engine) for an accessibility change
As-is I get nausea issues and headache problems when the camera hugs the wall or other issues that were not present in the previous games because the shoulder swap was allowed. The mod is a simple boolean change which the creator states “changes the blockCameraSwitch that was added in an early patch to false”.
