Thanks to an offer by ATi, I am now in possession of Half Life 2: Deathmatch and Half Life 2: Lost Coast, but no other “Source” games. Will I be able to play Black Mesa without purchasing any other games?
Welcome to the forums. No you will not. You have to actually buy a source game. And the thread for small questions is here
thank you, that was helpful, especially to a n00b like me. By the way, Deathmatch appears in the list of “Accepted” games on the big important thread thing.
Yes, but unfortunately they don’t mean the free version. It’s because the free versions of both hl2:dm and lost coast do not include source SDK, which is necessary to run this mod. The easiest (cheapest 
) way is to ask someone to gift you a copy of hl2.
Actually I bought orange box for 10dollars, I don’t suppose you can’t afford that, and it’s pretty worth it IMO.
The Orange Box is DEFINITELY worth it for $10 which is about £7 sterling… or something. By the way, that link I gave for people with ATi graphics cards allows you to get money off some Half Life games or something like that.
Than what are you waiting for? Go get it!
What are you talking about? the $10 Orange Box or reduced price Steam games? Both? probably.
EDIT: I have no real need to buy it now, though, as I have the console port of Orange Box (PS3)
Euw.
TF2 is awesome on PC. I can’t imagine trying to snipe with those thumb fucksticks.
Anywho, you’ll have to buy something from this list in order to get the SDK which is required to play Black Mesa
Yeah, i really need a good Joypad as I hate keyboards. and the PS3 version of TF2 has only… 6 maps.
I’m confused. I thought Black Mesa was free?
The mod itself is, but you have to have purchased a Source game in order to play it.
So technically, it’s not free. At least for those who haven’t purchased a Source game…
Question. I’m reinstalling Episode One. It’s also asking me if I want to install Half Life 2: Death Match and Half Life Death Match: Source. Is DM: Source okay to be able to play BM now? or no?
If you have episode 1 you can play teh blakl mezaz
Black mesa is not a new game in itself its a mod, A modification of an already created game.
therefore you need an already existing version of the game its modifying.
The mod is free, the game is not.
I think it speaks for itself that in order to play a modification you’d the game it was modified from, no?
So when Keresh says you have to purchase a “Source” game, we’re talking about the source game “engine” the main games (HL2-EP1-EP2) use, yea?
I don’t know honestly. I’m not familiar with how this works. Isn’t Black Mesa its own game? Why would it need a past game (HL2-EP1-EP2) in order to work? I can understand you needing the system requirements of these games but I would have thought it would stand on it’s own if you wanted to play it?
Luckily I have Episode One then. 
It needs an existing game, because Black Mesa is simply made up of textures, 3d models, scripts and code. The actual engine the game is build on (source engine) does not belong to the BM team, it belongs to Valve. That’s why you need to buy a Source game in order to play it.
And technically its not a source game itself that you need, its the “source sdk base”, which is only available with a RETAIL version of any of the source games.
Well, it will sort of stand alone, in the way that you won’t be opening the EP2 to start Black Mesa, it will have it’s own game files, but it will also use the engine from EP2 and the shared files. The game isn’t being made by valve so they can’t make it truly stand alone, that’s not legal.
Edit: Ninja’d, also ManlyStumb explained it much more clearly.
Fix’d.
