Yesterday I was playing around with this game and managed to clip through the wall to turn on the gas pumps: I assume this is already common knowledge but you seem to be able to climb more slopes if you walk diagonally backwards.

Backwards walking and other memes.

You need to block the area where your character would exit from the back of the truck, on the side away from the wall, then you have to figure out the specific angle that is needed to clip through the wall, then you spam enter/exit on the seating position near the wall at the back of the truck for a very short while, basically just until you get off of the vehicle, which should put you on the other side of the wall. (I apologize for the controller on screen when I was using keyboard/mouse, but it was easier to mess around using that)

Title tells the story, I haven't been able to find any triggers outside the map, at least not yet. The only thing I haven't yet been capable of doing is to jump from the hill to the right, which is climbable without being reset, and then jump onto the rocks that I run through. Side note: Holding W & D and mashing jump as I did to get up the wall after placing the car can completely replace walking diagonally up walls, it also seems a lot better for climbing the walls.

Someone who's good at the game needs to do some timing of this compared to the normal route, because all I managed to do well was the drive back..

You can clip through a lot of thing idk if any of the clips are useful. Oh yeah you don’t need a vehicle either.
