Quick tutorial for teleport/Warp glitch! (Read description) https://youtu.be/_K2ywf2rtv
all in all, there is still a lot to be tried out, but it's a little way off to see it in the Any% category some days
I can not see the videos either, not anymore at least. I'm also quite interested as to how exactly you did this, and if it even can be replicated for PC in the first place, seeing as you're doing this on PS2
Check out the persons youtube account, they are watchable there. Not sure why it isn't working here.
So I was able to do the warp trick once on Xbox, not sure why though, my controller disconnected during the attempt. I was able to get the get into cover prompt in the car but could not activate the cover when leaving the vehicle. Looking at the video, the prompt stays on screen longer after you leave your car on the PS2 version rather than the Xbox version. My guess it has to do with lag/low framerate and the console taking longer to process everything.
I did it! Low framerate makes it easier. I used the smoke on the car to make a low framerate and it made the trick possible. (ON Xbox)
