The architecture in this scenario is impeccable. This RyokoTK deserves the highest applaud for the effort he put into this masterpiece. inf/5 rating, but 5 is the highest available. RyokoTK, make scenarios like this one, and you'll get me hooked.

Btw, Stone Temple Pilates at Normal is wicked difficult. Serial number of tries just to make it about the 20th time? Relentless brutality, but it's the way it should be. Rock on RyokoTK.
AND HONESTLY, Phoenix beats the original Marathon trilogy. Played it more than the originals.

So far, I'm at Tantive IV in Total Carnage difficulty - wonderful and difficult scenario, surprisingly beatable in TC.
A 35-level single player major conversion.
This scenario is difficult and action-packed; it features a full arsenal of new, powerful weapons, and more threatening enemies than you could ever want.
1.4 has new Lua features like a performance overlay, weapon buffs, a lot of little bug fixes; it also applies ammo capacity limits on Total Carnage. Requires Aleph One 1.5 or newer, probably!
