I wouldn´t call the Backwards bug a Cheat at all, it doesn´t make the Game easier in any way whatsoever. Sometimes it even can destroy the Mood what was supposed to be conveyed. Here you can also clearly see the more advanced Lighting of Unreal Engine 5 against the original Fox Engine. Dynamic Lights just look better period. When you do the Glitch in the Original Game you can clearly see the Developers not intended for you to do this, this is not the case here.
I hope i didn´t sound harsh with my I hope you don´t expect Line. If i did I am sorry. That was not my Intention.
And lastly you can check the Fog Glitch out in my Youtube Video just in case you are curious...btw the unedited Raw Video was 1 and half hour long, way too long...
