A very long time ago, RevBillyG had an idea: a map whose central feature was a giant swinging pendulum. A crusher, in fact. What he didn't know was that this pendulum would have a subconscious influence on both him and the map, and that his map would return over and over again. Just like the pendulum, in fact.
After the original Jailbreak III version, called simply Crusher, Rev worked on a version for Jailbreak 2004, called Crusher2k4. The change of style for that one didn't work out, so he made Crusher2 instead. And now he's remade Crusher2, and it's called Crusher3.
After all that history, you need a break. Download this excellent map from NaliCity and give it a play.
