Downloading and playing custom maps?

[DriZzT]

Hi,

I am working on 100k kills and still have 67k left. So I was looking for the best method and found an achievement map for this. But my question is: Is that ok? Can I use maps like this?

I found this site: http://asmox1e.blogspot.de/2011/05/alien-swarm-how-to-get-nuke-from-orbit.html

It is a vpk file.

that wasnt exactly my question. i asked because of VAC. dedicated servers have this VAC icon and i was not sure if that is a problem when i am using custom content.

but i also posted in vac forums and they said it is ok because i don't modify any original files.

and for your information: you get 10.000 kills in arond 4min 30sec.
