They patched the drill method as you are meant to use the rope (you can use the rope multiple times)
The idea behind this mission is to use the ninja rope contained within the right supply crate, to navigate around the outside edge of the moon, then down to the bottom center, where a tunnel leads straight up to the weapons crate which is the main objective of this puzzle. Unless you're a pro at the ninja rope, expect frustration, as it took me around 30 tries to get this right.
The left supply crate contains a pneumatic drill, which is completely worthless and should be ignored, since it can't really help in this mission. Using my first worm at 1 health, I walk him to the right edge, to drop down and fall on the supply crate containing the ninja rope below. This fall causes him to detonate himself after sliding to the right, causing the sentry gun on that side to be thrown off the map. Next worm up, I take and snap the ninja rope onto the floating satellite to the right, and drop down with the rope, making small swing and re-attachments as I reach the bottom edge.
Be most careful at the bottom part, as it's possible to touch the water and perish during the attempt. Once I snap the rope into the tunnel leading up, and reach the crate, I am given the use of the Armageddon weapon. Using this weapon calls down fiery meteors that destroy the entire top of the map along with all the worms that once stood there. This completes mission 30 in Worms Reloaded.
