Cody Munholland ("Goku") originally created two versions of the Escape map: an easy version that had a few extra checkpoints and some "boost rings" that served as free tickets right to the end of their respective obstacles, and a hard version that removed the boosts and knocked out a few extra platforms for the hell of it. The hard version, in particular its brutal final section, has been a rite of passage for players looking to make the most of the movement system.
Entry to the club just got harder.
shirepirate started working on a reskin of Escape a while ago, to get rid of those goofy computer monitor textures on the walls, and eventually got to making changes to the geometry itself. Then adding completely new areas, so that legendary 115-meter U-shaped dash across water, lasers, and low ceilings...is no longer the finish line you're looking for. In fact, it's barely halfway. I joined the remodeling effort at some point, and now you can drive yourself insane like never before.
Warning: This is an extremely difficult map to complete all the way, although it has been tested to completion under both 1.4 and 1.5 physics. If you can't get through all the official trials comfortably, suffice it to say you're not going to get very far in this one. You can still download it, though, so that one day when you're adept enough to get through all those maps, you can move on to testing yourself with some custom maps that are a bit harder...and then, finally, you might have what it takes to get through this whole map. And on that day, all will be right with the world.
"Sure, you cleared out the lava and filled in the space with something less intimidating, but I still can't swim. Remember? Oh, but...I thought that after that long wallrun to the left, the hole was supposed to go DOWN, progressing to the next section. What kind of sick contraption could be off to the left?"
"And all the red obstacles look like they've been hit with buildups of extra water. How do you expect me to jump across that?"
"Well done, apprentice. Obviously, this place doesn't correspond to anything that's been in your memory bank. The good news is, you're almost done. The bad news is, you're way down there and the exit tunnel is way up here. Clearly, in order to get to where you are now, you've already had to cross a 75-meter gap using nothing but your imagination, so I know you believe in yourself. But this one's different. This time, you're fighting against gravity itself, and these four blocks in the sky are all the support you get. You don't want to watch your hope dwindle away to nothingness here, of all places, right?"
(Note: Neither of us is much good with the lights, so that aspect of the level may be due for tweaking in a later version. Unfortunately, the group of people who know good aesthetics in map lighting, and the group that's interested in challenging a map like this, tend not to have much overlap.)
