dont even need to jump. Just walk up to it and hold forward. You'll walk straight up it. Heck, you can even do it with a strafe key. Comes in handy sometimesi seen it on many maps.. anywhere theres a corner.. you can do the same method just jumping and it would be like going up steps if i can recall it correctly.
So alot of people encountered this bug but was never able to report this? Even as it is so minor. :|
Basically, yes. I do it all the time on the front of DX bases, so I was sortof disappointed to see that front 'lip' on the Gorge bases that prevents me from doing the same. Oh well...Think of it as our version of the tribes "grip the edge of everything" trick (which it is).
