ESHQ is a mod for Half-Life with its own storyline (not from Half-Life universe). Unknown government spy must steal secret files from the building called “Evil scientists headquarters”. But his job gonna be a bit more difficult and long...

ESHQ is an abbreviation that means “Evil scientists headquarters”. This is the name for the fake experimental center, used for distraction from the real infrastructure complex:

  • “Bernier city experimental complex”. It exists independently from city administration and other buildings. Base consists of five separated bases and other buildings connected with subsurface transport system.
  • “Base 1”. The object works at aqua biology and same technologies. It has an underwater “garden”. Base is connected to the common railway.
  • “Base 2”. This object worked with surface fauna. It had an own warehouse complex, connected to the common railway. Base has been closed and sealed after the unsuccessful experiment.
  • “Base 3”. It works at weather control. The object has been placed into the Bernier mountain. It uses its own transport railways, connected to common railway and teleports system. Weather control facility was developed with constructive mistakes. Probably, it is the real headquarters of the entire complex.
  • “Base 4”. The object works with reality imitation technologies. It has its own missile arsenal and rocket bunker (probably, left by old “Base 5”). Base is connected to the common railway and teleport system.
  • “Base 5”. The object works with weapons. It’s about 100 km from the city. Base has its own tectonic laboratory and surgery complex. It is connected to the common surface railway.
  • “Bernier city secret transport system”. It is the complex of railway and teleport hubs and tunnels. The object uses teleportation core and its own reactor complex.

This organization has an antagonist – the “Sampi research complex”. Probably, the ESHQ was the part of Sampi, but it hasn’t been confirmed. It consists of three separated sectors and the headquarters:

  • “Onground and subsurface Sampi station”. The object includes, basically, living and storage areas, test sites, etc.
  • “Deepcave Sampi station”. The object performs forbidden biological and radiological experiments, teleportation tests, “living without sun” psychological researches.
  • “Sampi space station”. This object is the large complex of space-station-like blocks (“columns”) used for “long staying in space” tests. Station has its own very powerful reactor complex, life supporting system, labs complex, etc.
  • “Sampi headquarters”. The object is the especial building placed in the Border world. This complex uses antigravitational materials and heavy-duty constructions. It has its own teleportation and gravity cores, underground city, etc.

Initially all of these points didn’t concern the protagonist in any way. But fate is unpredictable. And now he need to go through all of this elements of evil...

Hi everyone!

We've updated our deployment tool Moddb.com to adapt it for Windows 10. In particular:

✅ The method for checking access rights has been completely rewritten. It now correctly detects problems with permissions to create files and entries in the Windows registry.

✅ A special section has been added to the user manual to troubleshoot access problems. The user will be automatically redirected there if the app cannot obtain the necessary access rights.

✅ Updated the self-updating algorithm. Previously, it used the file version substitution in the file name to circumvent the ban on overwriting the executable file. In this form, the algorithm would require granting administrator rights to the app after each update. Now a more “conservative” bypass scheme is used, which allows you to assign permissions once and for all.

So, now this thing should be more useful on actual operating systems. If not, you still can use stand-alone 7Z archives to update our mods. In any case, thanks for helping us improve it.

Best regards,
Nicolay B. aka RD_AAOW

I thought I had been playing version 14 (I downloaded it on March 20th via the deployment program) but when I select "Custom Game", it says it's version 13.10.4... have I been playing an outdated version this whole time?

Hi!

Don't worry. The actual assembly just contains the wrong version file. It doesn't affect the other content.

If you can find a fog on the last map (with the time machine), you have an actual version

Okay, thank you! It does have the fog, sorry for responding so late. I did an LP series of this game on my YT channel if you are interested! I've wanted to for a long time, and finally got around to it with Ver. 14! It's been fun watching this mod come as far as it has. I do have a question though, didn't you say quite a while back there would be additional stand alone episodes that expand on parts of the story or something? Have any of those been released?

LP = longplay? If so, this is a great opportunity for us to see how it works “outside the test chamber”. We’re using these videos to find bugs, mapping mistakes, inconveniences and difficulties which would otherwise remain invisible to us. After that we can do some improvements and release a better version of ESHQ.

About your question. Unfortunately, I’ve missed that inspiration, and the idea of “From aside” is deeply sleeping now. The only thing I can maintain now is ES: Randomaze, the plotless PvE (I guess?) shooter with the configurable maps generator

Hi!

You probably looked at the old repository. Here’s the new one: Github.com. It is still open-source, according to the “mother” license

Hi!

If I understand you correctly, this work is almost completed. We have some lines that need to be re-recorded. But for now it's not critical
