Not necessarily. If you own absolutely no Source games at all, then you can buy it, and you can then run Garry's Mod. A lot of Garry's Mod addons require Counter-Strike Source though, so it's recommended, not required.
No you cannot because Counter Strike 1.6 runs on the original counter strike engine. Every game on garrysmod must run from the Source Engine or any game ran off of HL2.
From my memory, These are the requirments. You must have ONE for gmod to work.
Garrys Mod*Required
Half Life 2 *You need this for basically everything in Garrys mod
Half Life 2 Episode One
Half Life 2 Episode Two
Counter Strike Source
Team Fortress 2
Half Life Source
Day of Defeat Source
well the garrys mod and cs both made by same company but they are two different games and are not crossmatched so no. You can make your own game modes in Garrys mod to have CS players yes and make your own maps ect. But to have garrys mod in CS game no.
No CS: GO is a new game completely so no need for the others.
You need half life if your want counter strike and Steam if you want to play online you can also buy it from Steam..
No, you do not need counter-strike to play gmod. I don't even have counter strike but i do have gmod. A word of warning though, a lot of the materials and weapons in counter strike are used in garrysmod. Mostly in mods, and maps. It is recommended to have it.
You need to have counter strike source installed to play trouble in terrorist town.
Yes you can,but you need to buy it at game stores that have Xbox games(It says Counter Strike on it) I have it by the way(Not Joking!).
you need source sdk
Counter Strike games are not free legally, if you would like to game, you need to pay to play.
Counter strike source is a small game, even my on-board laptop graphics card work with it and its 780MB
You can disable it when your MOTD shows up and the message comes out.
No, it is already a keyboard.
NO - I have winows 7 and I have counter-strike condition zero AND Counter-Strike 1.6 and they both work fine.
In order to update Counter Strike: Source you will need to update the Steam system. See related links for more information.
I think i answered your question on the other one you posted. You need to delete a file from your game thats whats causing an error. C: Programfiles steam counter strike counter strike 1.6 all files will be held there
