Dont Fall down

Name of glitch: Dont Fall down
Gamertag: MAN8FREEDOM

In Turok on CO-OP the 4 mission (i think) you go onto the second floor and onto the tree that is bent. Jump and if yo hit the right position you stay on. Walk up untill you stop. Jump forward and keep a little t the left. When you did that keep goin. You might stop again so do the same. You reach the top where its most likely impossible anywhere else. Here the catch. what for the black holes. you fall down and have to wait for at least one minute!
