The map needs to be expanded. The hotel needs to be bigger and their needs to be more shops I would say 2 or 3 more. Their should also be a bigger police station.

Duly noted, but what should be in the police station in the first place?

police stations tend to look nice with combine control panels and furniture.
aslo you should make mining tunnels with ridable minecarts.

let me just request something simple, all windows be breakable

Here are my pd reccomendations, 1 cellblock (way to escape???) with 3 concrete, windowless cells, a camera room to see around the map, a button to engadge a lockdown (metal sheets go over windows and doors close/lock) and an armory that spawns HL2 pistols and shotguns.
I do believe every house should have at least a kitchen area and a bathroom area (or at least a community kitchen/bathroom in every living area)

Some ai nodes can help those casual npc interaction fanatics like me :D

you should add a button to toggle the waterfall on and off, because it kinda lags a little bit

Make more Houses on the sides of the wall and the the walk ways bigger so it could be use for bigger servers

there should be a switch on or near the generator (in the lowest house) which turns off all the lights and stops the tram

@ Freakyfish45: I'm trying to stay away from combine stuff but the minecarts are an idea.
@King Splurge: Will do, with buttons to disable and fix them too.
@carroll: I'm ging to add more cells but keep them in the open, that way its public humiliation. Guns are an idea and I'll add kitchens/bathrooms.
@Lurker: AI nodes will be done.
@pjmd009: There is buttons to toggle it, as mentioned in the description. Its at the end of the tunnel across from spawn.
@King Potato: Houses are a must but I'm not sure about the bigger walkways. I didn't think players got stuck on eachother.
@echo: I tried something like that but toggable lights look like crap :(

Maybe a "broken" house with zombies n stuff without light ?

more normal houses

Are the houses at the top too small? Or should I just make anymore houses bigger?
