Step 1: start at the circle which is the farthest in you can go without glitching through. squirm around a bit, then go backwards, a little bit right, then forward and a little bit left, this should bring you through the guard and the wall.
Step 2: from where you end in step 1, go downwards and to the right, then upwards and to the left. but as you go upwards to the left, dont go back to the same spot you were in, try to be a little bit in front of where you were (follow the zig zags)
Step 3: after you do enough 'zig zags' you should automatically glitch up onto the ledge thing.
Step 1: repeat step 1 of the first picture to get on the other side of the little wall of guards. continue to go down and to the right, then instead of going back up, squirm around and try to get farther over to the right.
Step 2+2 1/2: proceed farther right and up to where the ramp and the ground meet. you should be at about the end of the swirly black graphic. follow the nice line i drew for you and cut across diagonally to the very right side of the ramp. it may take a few tries, but when you get it right, you'll go right up.
Step 3: continue up the ramp until you are in an open area that you can move freely in.
Step 4: you have done it! now you can be leet and flash your bambi to the unranked noobs below you :P. you can also proceed to go farther back, all the way across the lava up to the mysterious door to The Underworld (the first map after defeating the zaishaiendinz guys. (sp? nah thats probably how you spell it.
hope you can understand it
