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

If VALVe Gets a new engine, they need to combine these two. Like a fitting death animation, then a ragdoll.

That would be cool, they did that in Bloody Good Time with the backstab. That pointing animation was priceless, and it was the best if they collapsed against a wall in front of a health kit.

Ragdoll, physics, more stuff than could possibly be placed in chat... I suggest watching videos of Half Life and then watching videos of the source enhanced version. The difference is obvious.
