I somehow accidently deleted the files, so now I don't have any prefabs, so no barriers, perk machines, power switches.

ummm I think I know what you mean

reply me back just to see: do you have your mod tool still installed or now you only have waw without it

2. if u only have your waw files with you (WITH NO MOD TOOL) download this with all the content exept for the script placer cuz that not what I think you would use 

3. If you still have your mod tool files download the same (download) as before but just drag the prefabs.

If your a experienced mapper you would understand I guess

Hope this help. MY PLEASURE.   Good luck

This is in the black ops 3 section so I would assume this has nothing to do with waw.

If you are missing any files just go to the mod tools in steam then verify integrity and it will download any missing files.

Oh shet im so embarresed well you can't find a link online

You should just be able to go into steam and verify the file integrity and it should re-download what you're missing. I could be wrong, but this seems like the easiest and most sane way I can think of going about this.
