Before I start, here's a screen that shows the upper part of the map so everybody can get an impression:
The buildings don't look bad, good choice of textures!
The map has lots of things that need to be addressed though. I don't think this list is complete, but here are some impressions and suggestions:
* item placement is a bit weird and needs lots of work
there's 2 GLs with 2 packs of ammo next to them, about 3 seconds apart. there are tons of ammo and weapons spread across the map. there's three RGs I remember, they can all be seen on the follwoing screenshot.
Also note that the bots tend to get stuck in the window at the third RG (marked in green, the 2 other RGs are marked in red here).
The RG tower that this screenshot was taken at sucks btw. The stairs you need to climb are very steep, lamps block your way so you have to crouch to pass underneath them and once you've made it up there and got the RG you need to climb down again because you can't jump out of the window.
* very huge line-of-sight in at least 2 places, one of them can be seen here (green line). this screenshot also shows a place where you cant jump up (red arrow) unless you're playing CPM and use a doublejump under the wooden plank.
* This door is somewhat strange. It's so small I could never get in there with the first try and it takes ages before it opens again if you missed the elevator that's hidden underneath.
* What's this point for? You have to use 3 jumppads (what seenms a bit exaggerated to me, see red arrows) to get there but there's no item there (green question mark, at least in FFA mode).
* The most important thing I noticed:
The lower part of the map (cellar) is very tight and there's no reason to go there. In the current state, the last thing is rather good because that whole place just simply sucks:
It's very tight and narrow. You can barely move in there (let alone fight), you get stuck in the walls, the ceiling, the skeletons and models and the jumppads. You bump your head. It's way to dark. Everything down there looks the same, it's confusing. I could go on about this but I think you get the point.
I suggest you completely drop it (or delete it and start over with a new cellar design). The next screenshot gives an impression of what I'm talking about.
small things i noticed:
* sky is missing (guess you know that)
* bots suck
* many small edges need clipping
* many of the corridors between the buildings are to narrow
* jumppads are tilted too much so you can't run onto them, you have to jump over the upper edge (I mean the JP at top of a building, one of the (3,4?) RLs is next to it).
* ground is very flat
There's lots of things to do but I think it was good that you posted the map in this early state. Hope this helped. Looking forward to the next version!
