Yo bitch boy.. Guess what? I'ma prove you wrong, as soon as I finish chopping a tiny segment out of my recording.
http://emulation-general.wikia.com/wiki/SCP_Driver_Package I asked some guys in the GTA community and this is what I was referred to. Might have to desync the controller from your PS3, or unplug the PS3, when using the controller on PC to not have it turn on and whatnot though.
Sorry for the late reply, you probably just wanna watch the world record and imitate what he does. The most important things in this game is to walk diagonally and achieve a specific amount of hearts devoured before a certain point, since you gain darkness levels based on the amount. I can't exactly remember how many is required, since it's been a long while since I ran the game. As for the splits, sorry, I don't have them on this computer. So you're just gonna have to copy them manually or figure out something on your own. Side note: I found a couple unreliable skips that save a minor amount of time, I'll just leave them here in case you're insane enough to go for them.
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.
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)
For the rocket powered WWII car there's a pretty easy reference as to where you can get OoB, on the side of the bridge towards Cletus' place between the fourth and fifth pillar on the railing counting from the one in front of the support structure(the orange metal beam) you should be able to just drive straight through the railing, you can literally line up from one side of the bridge and just drive towards it and get OoB. At least if my terrible memory doesn't deceive me that's the reference that I found for that vehicle.
Glitch impossible with family sedan, or at least I haven't been able to get it because the body of the car is too close to the ground, however the pickup vehicle in level one is capable of performing the OoB. The glitch is also possible to execute with the Canyonero, however it seems very inconsistent, mostly due to the canyonero having a tendency to bounce over the railing and get more upwards momentum than forwards. I have not figured out any reference points for this or anything though. Have fun - Cob.
I don't know if this is faster than the current route, I haven't timed it at all, I just thought I'd share it regardless.
I did some more fooling around with the OoB part of the glitch and tested it for Lisa's level. I couldn't think of much other use than something like this. (I do apologize for having to cut the video, I was derping around seeing if I could go anywhere with the broken vehicle that I couldn't otherwise) Also, the floor seems to be dependent on the height Lisa is at but jumping and not landing on a rendered surface will lead to a quick trip to the void. In any case you seem to be boxed in within the constraints of the invisible walls around the roads, however if you get close to them you can car reset and get on them. I don't understand what dictates whether or not the area you reset to loads or not since I've had both unloaded areas and loaded areas happen when resetting onto roads.
I just kinda come up with a concept, spent ten minutes bitching at the game, executed what I wanted to and turned the game off.
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.
A couple reset strats I found ages age that might help, since no one seems to remember them. Note: on the first one you have to turn a bit to the left or you will end up being faced in the wrong direction once you respawn at the end of the road.
