Installing Gmod9

Can someone tell me how do I install Garrys Mod 9 in Portal 2? Well I do not have CSS or any HL, but as Portal 2 is of the Source engine, I think that would work … Someone give me a hand?

  1. Garrys mod 9 is outdated and unsupported, buy gmod 10.
  2. You don’t install Garrys mod to a game, Garrys mod is a mod that requires a source game to run.
  3. For Garrys mod 10 you need atleast 1 source game such as CSS or HL2, otherwise it won’t work.
    Portal 2 is not a compatible source engine for Garrys mod 10. You still need CSS or HL2 if you plan to buy it.

Hm… Ok, i understand. Thanks. :smiley:

I think you need both Half-Life 2 and Counter-Strike: Source to run it correctly, unless you delete all of the CS:S related files inside of the mod folder.
