Hello,
Me and Alternax have discovered a new glitch in W:A.
It requires a girder and a ninja rope to be performed. Fire the ninja rope, don't press anything, just wait until it stops moving, then select a girder and place it on the rope. After this, release the rope - your worm will fall down with a doubled velocity.
I'm not sure whether this glitch is already known or not, just didn't find it anywhere else.
No add-ons were used when performing this glitch. It's properly a W:A's glitch.
Note: this glitch will not occur if you have just shot the rope at 90 degrees (without shaking before).
PS: I didn't attach the gif since it won't tell much by itself anyway
