Check out the videos, I promise you guys won't be disappointed with some of the cool jumps I discovered. (Only problem is you have to download them from my FileShare)
**please leave comments of the videos if you watched them**
Some of the jumps include jumping up and getting the rockets just after you spawned on Red Side, jumping to the outer limits of the map and many others, I used the Bruteshot to do jumps but nades work fine too
