Arguably indeed.

I do not think this is a good map for any serious game mode. Seemingly random sprawling passages, dead ends, repetitive textures, in short not good artistically or for gameplay. 4/10 rating.
I suppose I should say some good points about this map, also. Where there is detail, it is okay IMO, though repetitive throughout the map. If you want to have the most fun playing this map, just wander around and explore it. I found that entertaining.

When you say "Arguably the greatest CTF map of all time", you set yourself up for criticism. This isn't really a good, playable map. I like the detailing, I like the toilets (hehe), but frankly, the long winded passageways and haphazard ammo placement doesn't make for good gameplay. If you didn't say it was a CTF map, I'd like it a whole lot more.
