You are in a small base and you must get 2 keys and destroy KaKoKa Balls and fight the evil Genius in the last room!. This level looks good but not as good as Kohe 3. Sorry but I will try harder next time.
From the author of maps 20&27 of Memento Mori. Fort Hades(27) was excellent, Mount Depot (20) was okayish and I found this one even weaker thanks to a marble-walled maze, a hidden mandatory blue key and a nonsensical BFG placement. However, I would recommend giving it a try not only to die-hard old school WADs enthusiasts; it is the most brutal map of the three, and this difficulty is what is the coolest and most redeeming here.
