September 2007 Update

I have a very big public apology to make: “ToTac kindly created a PlanetPhillip version of this mod, which contains Englsih subtitles and is Steam compatible, and I forgot to upload it and promote it. For this I am truely sorry. I wish I had a good explanation but I don’t.”

If you haven’t already played this mod or you want to know what happended!, they I highly reccomend you downloading it and playing it.

I have just played the training room again and finally, yes finally, managed to completed it. By doing so, you gain access to a special “Shoot the G-man target” level.

Installation is very simply via a wizard.

About

This modification has 17 levels and plenty of action. The screenshots are from the first third of the mod. I had a lot of trouble with it and eventually gave up after it froze on me. However, the mod was never designed to run on Steam and was built for Half-Life 1.0.0.9, so that’s not a criticism of the developers, just a statement of my experience.

It apparently appeared on a German PC game magazine’s CD. Thanks to beowulf70 via the Ten Four forums for uploading it.

Steam Installation

I created a folder called underground in my Steam installation, for example:
C:\Program Files\Steam\steamapps\YOURUSERNAME\half-life\underground
and then extracted the files into that. It then appeared in my Games list in Steam.

Warning

I had to cheat, so some of the screenshots are not fair representations of what you may face. Also all the text is in German. It would be cool if the HL Community could translate the text and make it Steam compatible. Anyway, enjoy!

  1. there’s a walkthrough for this mod :D PP, can you put the link?

    Fixed, thanks.

  2. hi!

    I have a problem. I don`t have a suit hev and I don`t see ammo, health and other. What I must do ?

    PLEASE HELP ME!

  3. Play It Later

    You have to find the suit.So before you pick up any weapons ask yourself if you really need it because you can’t switch.If I remember right I played with just the crowbar till I got the suit.

  4. I think you can switch with your scroll wheel; you just can’t see what you’re doing.

  5. On some mods I can and some I cant.This one I cant use the scroll nor the last weapon key.

    Strange.

  6. Oh. Likely you played the original version. Its default config file didn’t bind “MWHEELDOWN” or “MWHEELUP,” and bound “q” to “quit” instead of “lastinv.”

  7. Play It Later

    i dont know why they made this so dark. You sometimes miss buttons and things like that, because it’s so dark! Otherwise than that it’s fine. Standard half-life adventure. Fighting grunts, aliens, solving little puzzles. Nothing complicated or long. No serious bugs in my version. Now, i don’t know if this was intended or not, but in the end level i took down two helicopters with one rocket! Mayby i was just lucky… A small download, with lots of playing time. Nothing wrong with it, except that it is all standard stuff, you’ve see a dozen times before. No points for originality.

  8. Play It Now!

    WOW I thought this was great!!! I am an HL player from 98, I was on a long break from playing and this is one of my first mods as a returning player. WOW it is good definitly play it I played it on medium level

    The guy who made this knows what makes Half-Life good. Claustrophobic level design, vent crawling and puzzles. He managed to keep the level design fresh even after all we’ve seen in the expansions and other mods. The ending was something I think we expected but the journey is what counts. I would love to see more from this guy, even if its not for HL.
