I am looking for any good parkour maps that are challenging. I'vs already completed all of m33taphor's parkour maps and those are probably the hardest parkour maps out there. I just want an equal challenge.
This is in the wrong section, but I'll still help you.
Look up "t3c", or "tetrix1993". In his third course, try challenge 13. It's pretty hard.
Also, I'm currently making an obstacle course that can get pretty extreme. It won't be released in a while, though.
