A slightly more difficult version of Heavy Machinery. The pipes you will encounter here will almost all be red and dangerous. At the beginning of the level you will already see the exit portal but obviously you will not be able to reach it, you will first have to overcome the entire path. There are no bonus rounds.
Getting the gem[edit]
If you reach the end of the level without losing lives and breaking all the boxes you will get a clear gem. There is only one difficult point, about halfway along the route, where there are several boxes suspended above a long void. You will have to break them all without falling. No colored gems are required, but if you already own the green gem (obtainable in The Lost City), at the beginning of the level you can climb on it and get many extra lives, and then go directly to the exit portal (if you want). This is a great way to earn lives if you've already got the clear gem.
