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.
no because garrys mod requires that you have a game that uses the source engine
Not specifically. You need a VALVE game to play Garry's Mod, one of which could be Half-Life 2.
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.
Any Source game. This includes: Half-Life 2 (You pretty much get stuff from this in any Source game) Half-Life 2: Episode 1 Half-Life 2: Episode 2 Team Fortress 2 Portal Counter-Strike: Source Day of Defeat: Source Get any 2 or more of these and you should be set to go, but I really honestly suggest getting all of them, its only about $50 (if you get the $30 Orange Box, which contains all Half-Life 2 games, Portal, and Team Fortress 2, then get CS:S for $20) Alternatively, Team Fortress 2 is now Free-to-Play and downloading that will allow you to play Gary's Mod, or any other Source mod!
Yes. If you have a Source game like Half-Life 2, HL2 Deathmatch, Counter-Strike Source, Left 4 Dead, Portal, Team Fortress 2, etc. you can play Half-Life 2 mods.
It depends on what the player does i guess But its mostly what Half Life 2 is rated If the player has counterstrike source also installed the content (Characters and guns) gets transferred to garrys mod so they can play around with it in the game, it depends on a few factors (1) what will they do? (2) what other games that rely on the source engine do they have installed? (3) what do you think is suitable for them in garrys mod, they are only limited by their imagination, in Garrys Mod you can build pretty much anything, and i mean anything
There is something called Decay on the first half-life where you play as two women during the incident. There is also a half-life 2: deathmatch, and that's more or less it. There is Half-Life Deathmatch and Half-Life Deathmatch: Source. You can also download a mod, "Sven Co-op", which allows you to play the Half-Life story with other players.
Yes, you can play online multiplayer.
no the games are different and they dont cross with eachother on the servers for game play.
yes if you have a legal copy from steam or from a shop you can i have purchased CS:S and Garrys mod together off steam so i can play Gmod.
goto droay two dirr
Yes. It is a multiplayer game.
