yes
Yes
Well, in the steams list of games which you can use on garrys mod it dosent show Half life Source. But if you type in gman squad on youtube you can see their playing the storyline on Half life Source. I asked them the same question and they said yes, you can play the storyline if you have garrys mod and Half Life Source. I dont know for sure because i have not yet tried it.
Y is there a xbox 360 garrys mod
no you cant but if you buy Half-Life 2 for PC you can get Gmod and mod the game ect.
no because garrys mod requires that you have a game that uses the source engine
go to steampowered.com make an account download steam on your computer and then go to the the search bar and type garrys mod and download it it cost $10 you have to have a game source though like half life the cheapest source is half life death match
Not specifically. You need a VALVE game to play Garry's Mod, one of which could be Half-Life 2.
No you need the full game or any other source engine
It is compatible with every game in the Orange Box.
There is no "Disk version" for garry's mod, you have to buy it from Steam
For Garry's Mod to work, you need to have downloaded at least one Source® game. This could be Half-Life 2, Counter-Strike:Source, or Team Fortress 2.
Buy Garry's mod 10 off of steam.
