Flydude got back to me and send me a copy. I'll keep it on my Microsoft Skydrive, which is publicly shared here:
It also has a few other maps that are personal favorites of mine.
ENC and JHS weren't meant to be serious levels. . . but when me and four other friends of mine get together and play them, we play with grapple hooks and the gameplay is just amazingly fun.
Thanks for helping out guys. Enjoy the game!
