Gold Source (also known as Gold Src) is a heavily-modified version of the original Quake 1 engine, that powered some of the most critically acclaimed games of it's day:

  • Half-Life
  • Half-Life: Opposing Force
  • Half-Life: Blue Shift
  • Team Fortress Classic
  • Counter-Strike
  • Day of Defeat
  • and many more.

A powerful and versatile engine for it's time, it helped propel modding forward quite a bit with its mod development tools. And even though it's already 10+ years old, it's mod projects are still going strong.

Welcome to our first media update this year!

Read Full Article.

Multiplayer Beta Release Q1 2014 Cancelled

Our plan to bring you the multiplayer beta of Operation Black Mesa early this year didn't work out, regrettably. Several factors and circumstances forced us to completely keep it under the hood until further notice.

Multiplayer Progress

Multiplayer will feature classic maps such as Yard, Crossfire and Boot Camp as well as brand-new ones like Deptcharge and Gambit from day 1.
Currently in development: CTF mode and weapon placement.


Singleplayer Campaign

Development is running smoothly; those NPCs aren't going to animate themselves though! If you're interested in joining our team, check out the jobs page where you can find all positions currently open. We look forward to welcoming you on board!

Pit Worm's Nest

Remember Guard Duty (Blue Shift: Source)? We're making solid progress here too:

Living Quarters Outbound

OBM: The Video Game?

We've been given the option of developing our projects as full indie titles to be sold on Steam!
This opens up a whole lot of attractive possibilities to consider; however no decision has been reached yet as to this matter.

Alien Controller

M1A1 Tank

Thanks for your support in making all of this possible!

Until next time,
Tripmine Dev Team

Yea, a 10 years old engine that can still kick some *** out there and its still remembered and always will. Who will ever remember CryEngine 3 in 2020? NO ONE I'm sure. They release new engines at the speed of light these days. Or better... tech demos passed off as "games"

All of you are just stupid geeks, I have nothing said bad about this engine and I got all retarded geeks attacking me. I just said that it was getting (very) old and that you should really evolve just a little (at least if want to make a carrer in the video games, who will want you if you only know how to work with 11 years old engines ?)

you know it's not that old I mean 10 years isn't old if Goldsource was like 80 years old then maybe people would stop using it but they most likely still will in 80 years. because all the new stuff like the UDK or
Cry-engine they're not a classic, when VALVe started out they had not idea what they were doing! but they made one the greatest games ever, so of course people will use they're first engine.

Evolve to what? Show me an engine better than GoldSrc. GoldSrc has legendary games. Half-Life, Opposing Force, and Counter Strike. And those have legendary mods. Half-Life is probably the most inspiring game ever. Maybe the graphics aren't that great, but so what. GoldSrc can do wonders, when put to the test.

And besides, we're making mods for fun, and for learning. Everyone needs a base.

GoldSrc is still awesome. I'm tired of people leaving it because it's "old". So is Queen Elizabeth. Does that mean those in england should leave it? No. Technology updates every day, but that doesn't mean it's better.

Another example, Disney. Around 6 years ago they were great. But then, they got Hannah Montana, High School Musical, Phil of the Future, Kim Possible, and all kinds of other dumb stuff, that the devil wouldn't play for anyone. Newer doesn't mean better.

and the first is Source, But are most HL1 mods on the gold engine?

I have played many single player mods for hl1 and its few of them that have the Gold Engine: Sven Coop, Afraid Of Monster, is those I can recall is on the Gold engine. (I know SC is both single and multiplayer)

And yes its more SP mods that useing gold, but i dont remeber the name of those, sry.

Agree it's the easiest modable engine if u look at the thing u need to learn from start, then Source/unreal/etc

Goldsource is simply the best. Not second. It has the best games, the easiest to mod, and the best community. Source is absolutely GREAT, but GoldSrc is better. More people should mod for GoldSrc. None should ever leave it.
