My NOLF2 mod is available for free at GitHub - LukeRoss00/nolf2-real-mod: R.E.A.L. mod - VR conversion for No One Lives Forever 2: A Spy in H.A.R.M.'s Way
There is no dedicated support for Pimax though, it used an embedded copy of Revive to run on headsets other than Oculus (GitHub - LukeRoss00/nolf2-real-mod: R.E.A.L. mod - VR conversion for No One Lives Forever 2: A Spy in H.A.R.M.'s Way)
