Well for most of them to work you need css, and hl2 dm
if your talking about the gmod that you buy off steam, nothing game wise oh, and $10
You probably have an illegal copy of the game. You must buy the game. it's only $10. you must also buy another source game to run gmod such as Half Life 2. then you can play online.
Gmod is only for the computer. You just install Steam (you can install it buy going to Steam.com) and then there you have it. But you will need a source, so will need to buy either Tam Fortress 2 or Half-Life. Gmod is also 10$.
Yes, you need a Steam account to purchase and play Garry's Mod (GMod). The game is available exclusively on the Steam platform, where you can buy, download, and manage it. Additionally, having a Steam account allows you to access community features, mods, and multiplayer gameplay.
You can buy it a garrys mod.com
if you have bought garrysmod on its own then that is your problem, you need to have another game to back up gmod otherwise you will have missing textures, ragdolls and guns, to solve this go onto steam and buy half life 2 or the orange box pack
no you cant but if you buy Half-Life 2 for PC you can get Gmod and mod the game ect.
css gmod
Buy sethhack from sethhack.net
(Before you start you need to download steam from steampowered.com) Go to garrysmod.com and go to download. It'll take you to the steampowered.com Garry's Mod page. You will need to buy it with a source engine game(unless you have the orange box or something). I think it costs like 25 bucks normally with a source. Without I'm pretty sure it's 10 bucks.
You need to buy an Action Replay or Gameshark. then enter the codes into there before playing the game
You need a computer that meets or exceeds the minumum system requirements for the game, an internet connection, and a way to pay for the game if you choose to pay for it. That is basically all you need.
