I was reading kilinrax's website the other day (nice layout BTW) and I noticed something on the obfuscations page. It says that Cursed Map "has yet to be successfully de-obfuscated by anyone."

Well, I took that as a challenge whether it was meant that way or not!

I had quite a bit of fun tearing this apart. I truly hope that I have successfully de-obfuscated it. I have to admit that it took longer than I initially thought that it would.

If you want to figure out Cursed Map for yourself, stop reading now!
