Gomorrah

Gomorrah is a GZDoom mapset consisting of 6 brand-new maps, powered by ukiro's amazing OTEX texture set. In Gomorrah, you'll be traversing three different locations - an abandoned mine/techbase, a medieval castle and a fortress in Hell - in search of three skull keys. Each skull key is going to be locked behind a puzzle which you'll have to solve. Once you have all three of them, you must use them to open a gate beyond which lies your final challenge.
