.. nearly left the comment for this one on one of the other two maps I just had a look at ... that would've been a shame - because this is the only one of the three I really like!
It's a bit full of mapmodels in some parts (especially one corridor is "blocked", you have to jump) .. but I like the layout very much and think it'll show some nice action!
You've also done a great bit of work on setting and detailing!!

Hey Undead, this is a really nice map. I do have some advice for you though, First the mapmodel you used...the soda can one is just bad, it doesn't fit into ac or your map. One of your custom textures looks bad also, the vent one look in CVS and you can find a other vent texture. Which brings me to my next point, with a name like ac_vent I was hoping to have more crouching areas but to my disappointment I only found one which doesn't look very natural. You should try to fix that up, and maybe add a another one if you find a good spot! The layout is solid for sure, looks good for tosok matches. I agree with meat on the detail, its quite good.
Oh, also on the wall with the barrel hooks you need to fix the fencepost.
Overall good map.

Yes, i was hoping that cleaner would make the soda machine texture it into a mapmodel for me. (he asked to do it himself) But, i couldn't hold off the map anymore and just left it as that. Hopefully he will finish it and i can place it in ;)

This map was originally called ac_crashed, then i renamed it to ac_drugs. After a while i renamed it to ac_vent. I'll try and find a spot to add another crouch spot dog ;). Keep in mind that in a fast game like AC too many crouch spots would make it too slow and also camping spots.

--edit--
Updated :D

I 'd give it a 4.8/5. Some places just look a little weird, but that's just me.

IMO the stainless steel texture looks horrible. It doesn't look good as a door and doesn't tile properly. I agree with the soda machine, a mapmodel would be much better. The map is very detailed, and evenly spaced.

Updated, again :)

Of course I like this map! ;)

Nevertheless there are some things I´d change. Little, unecessary things in general.

The only big point is the area where the stairs lead up to the bridge. I didn´t like this very much from the start, tbh. See, there´s a bridge, you have to climb up on each sided, but it´s not leading to an elevated level.

Actually there´s no need to use the bridge, as long as you keep a 'realistic' view on it. I would create one room, as high as the bridge there.

Hope that was understandable... :)

Yes you made sense floppy.
Its basically a path from one building to another, it doesnt have to be TOTALLY realistic man. You see not everything in AC is like that, i mean ac_desert doesnt look EXACTLY like a desert village does it? ;)

Thanks for the comments and rates guys, final update soon.

Final update, give it a rate.

Nice undead very nice map i like more in tosok ;-)
