/DOUBLE JUMP/: If you are on a slope made of stairs (example: the staircase on SECRET STAIRCASE) After you jump you can perform a second jump by pressing w/up key when you are on the vertex (point) of the stair.
/DEATH WALL/: 1:On the area with the wall of saws blocking your way, if you take the top bumper as high as you can and as far right as you can plus using flow, you will land onto the conveyor belt by the second death wall. Major shortcut. 2: On the part with the isolated bumpers, If you take the first on as high as possible you can skip a bumper, then from that bumper you can shoot al the way to the checkpoint. VERY handy.
/MARATHON/: At the area with the three bumpers and the saws ahead of you, you can simply jump over the bumpers, slip under the saws, and take a nice slick shorcut.
/TUBES/: At the scene with the big gap the axe to the right and the teleporter at the bottom, if you jump at the right time you will jump completely over the gap and hit the teleporter. Quickly jump out of the bottom teleporter you move to then move back in. This will save you lots of time.
You should have just put all these levels in one post. @dhudfw That's all you got? Where's the secrets? Where's the walkthrough? This is a walkthrough.
be careful with the cut that gets u to the 2nd conveyor belt. it's VERY risky. ive used it a lot in the past. if u ont time it PERFECTLY and get some luck, u WILL get hit by the axe, die, and likely not finish unless every1 else in the room sux.
