DepotDownloader VS xash-rt

There's also DepotDownloader that lets you download anything, including past version, from Steam https://github.com/SteamRE/DepotDownloader

I use this to download historical versions of a game to help with reverse engineering to archive dialogue trees from a game https://dialogue.destiny.report

I'm not sure how you could just download the launcher. You want the Launcher.exe from this version. A quick google brought up this downloader: https://github.com/SteamRE/DepotDownloader

Steam Depot Downloader (requires DotNet)

Continuing to add to the confusion on the topic by trying to argue that Steam is DRM because you have to buy the game through Steam is counter-productive. (And apparently Steam's client isn't the only browser available.)

Not by Steam means. I don't know if it's still functional (update on last year) but https://github.com/SteamRE/DepotDownloader is what you're looking for and you need to learn the DLCs depot number from SteamDB to feed that information into this program.

use this https://github.com/SteamRE/DepotDownloader

If you are looking for a specific version of the game and you own it on steam you could download it using something like DepotDownloader. An example of this would be downloading the first pubic version of the game

You can still rollback with the help of the DepotDownloader: https://github.com/SteamRE/DepotDownloader

There is a mod for that, unsure if it works with this new release though, but try it out and report back :)

Another option, btw, if your PC is up to it: there has been a really nice release of a raytracing mod for HL rather recently (https://github.com/sultim-t/xash-rt/releases), this also breathes some live into the old game.

I'm excited to go through the original HL again. I started when the pathtracer, Xash-RT was released, but then MMod v2 dropped, and I want to combine them so bad. It's not as simple as a drop in mod though. mmod needs to be 'recompiled' to be compatible with the new renderer as stated here. In addition mmod uses new models with new textures, and they would need to be given some tweaks to support the pathtracing PBR features. (Might be nice to sneak in some ReSrced textures where appropriate too, although they do have that AI upscaled look about them)
