When you revise your map cs_gangstahouse, let me know and i will make a video of it.

You said;
Ok. But I have to make note that I may or may not use your exact NAV, as this left still needs revamping. You should wait until I have the project finished.

I can take the nav and change it where you changed the map this nav will work for all your versions I may have to tweak it a little but that is way better than making a whole new nav.

I can recommend 3 changes you can make that will improve the map immensely, right now it has one way out of the building [with hostages] a strangle point. It has one HRZ another strangle point.

make a second HRZ outside the back door of the ct spawn building.
make a doorway downstairs on the side of the building closest to ct spawn behind the fence.
make a breakable section of fence or a gate along the back of the house the side with the ladder.

That would make the map more even and give the terrorist more to cover.

you can use sounds from other games as long as it isn't the same file or you created it
also, for hallways I like to make it so spys can't get by without touching people in the way, depends on what your looking for

You can cough* edit the sound files so they are not the same and then try to bring it back as close as possibe
