So... now with some more qualified comment.
As fnb said, the map is reminiscing on the good old days of UT. Not too many details, just mindlessly bastling away. And for that, it works for the most part. The setting of an urban city block works surprisingly well. The rundown blocks are working quite well, and even the hightech stuff doesn't detract. I know you wanted to recreate an environment theme from another game, but that blue tower is looking quite out of place. I would have probably used something else for the shanechurch textures, as well, but I'm not very familiar with the source material either. It's not super detailed but it works. I love the speeding cars, though. Flashy and deadly, and you found a good way to make them solid.
Now for the more techy stuff:
- brush612 needs to be solid (missing textures due to bad cut)
- brush883 needs to be solid (missing textures due to bad cut)
- brush277 needs to be solid (see above)
- brush965 needs to be solid - same as above. The way you place those *can* work, but it's really wonky. The legacy wiki has a small page here.
Not super helpful but it's a source at least.
- brush576 and the other pillars don't have collision, you can jump right through. Needs to be solid again. The whole area in general needs a rework, most of its errors stem from the zone portal.
- movers 4 to 6 could be changed to Movebytime to make it easier for bots. Well, all lifts actually could.
Now for gameplay. While it's a big map, most of the action is centered around the rundown building with the cars parked atop (see car16 for reference point). This is due to how much stuff is lying around. The map is crammed with guns and equipment, and basically 90% of bots were running around with the minigun. You could easily throw out around 60 - 75% of the weapons here I think. Maybe not as much, would have to playtest, but you could make each building / area in the map more unique and reasonable to travel to. Also, spread out health a bit more to different areas. A good example is the center workshop with the redeemer on in. The tower was mostly unpopulated. A stray bot went for the invisibility once but the place was pretty empty otherwise. SniperRifle0 is a weird place as well. It should be placed in a place where you can acutally snipe, like the subway nearby (which is, ironically, missing a weapon).
So I'd throw out a good amount of weapons, limiting available weapons to like 2 or 3 per building and always tied to the location they're in. Flak in the workshop is good. It's tight. You could place on in the bar in exchange for the rocket launcher. Not completely sure about it. Like I said, try each location with 2 to 3 guns tops and spread them out, so there's reason to travel to the far off places.
This also includes super pickups. Shieldbelt and Udam are fine, but I think invisibility and the redeemer could be placed in more remote / dangerous places.
Still, I somewhat liked the map. For now it's rather campy / mindless fragging, but it still has potential. Good job, hope it helps.
