ohh
yes, you should really do the underground base, but make it have only one entrance and if you make is super complex, plz name the rooms with signs. All these other maps i've played have giant confusing bunkers and all i want is one that is simple and effective, instead of scary maze thing that i have to noclip through.
hope you update it soon!
best of luck

A destroyed city will be awesome!

for the destroyed city / prison could there be a power station so the citys etc doesnt have power when you spawn in but if you go to the power station and turn it on the lights in the town / prison will be on (being able to turn and turn off power)

I would like a map (shouldnt be rp) but where you can fight ncps in a wasteland like style where the map is open world.... if you can do that you are awesme. My idea for you would include a messed up city but have some survivor settlements

I think there should be some sort of shelter.

Create some vaults on the map (for example vault 111)

Mayhaps a mineshift or similar haphazard underground complex.

a abandoned red rocket gas station with a destroyed car maybe?

I like the walled off survivor settlement idea

Destroyed City/Prison (Combine) (Give me a message and I might help you with the map if you want)/Combine Outpost.

I have na idea, how about Arkham Asylum! No one has doen that before!

some of "No Mans Land" or a a big crater that leads into a massive underground cave system

This is your map so you don't have to take my suggestions if you don't want to - A shanty town

- A failed nuke in the ground

- An abondoned schools

-An impact crater with nothing in it or a meteor in it.


As said before this is your map and you don't have to take my suggestions

Could ya add some HL2Beta stuff? Like pipes run through the entire map or depot in the background.

Maybe a old construction sight.
