gmod and cs

so it has come to my attention that alot of files downloaded off of gmod.com require cs or cs:s to work. So I am willing to buy cs but I want to know if the games have different weapons of files or it they are the same

Do not buy CS but CS:S only if you want to have the content inside Garry’s Mod. Also, CS:S is different from Garry’s Mod, it has different weapons and gameplay but file structure and engine are the same.

buy counter strike source
not counter-strike

then it will work

of course I have to buy the more expensive one…fuckin valve

but thanks

Counter-Strike 1.6 will not work in Garry’s mod because it runs on the Goldsouce engine.
You only need Counter-Strike: Source.
