I had to snap a picture with my phone

I'll add my 2 cents as well,original doom 3 download page is empty.The offline installer is the only version i'm interested in.

not quite drm, you only need galaxy to install it, but not to play it

IMSHO that's DRM, Galaxy goes down, no Doom 3...

I need the offline installers cos I play on Linux, first time I seen a game without the installers and it's a pain to use Galaxy, really need the installers to be honest.

Same, it's really frustrating to see an item on your collection page and zero link at all, I'm on Win10 so I could use Galaxy, but I prefer the offline installers.

I got it to work by downloading with Heroic Games Launcher, and pasted the keys into doomkey/xpkey and it all worked, but I would prefer the installers for safe keeping etc

Installers just appeared for me!!

Good news, people ! Offline installer is now available ! :D

Is the addon include in that one installer or is the addon still missing?

It's built-in. Just install and click on the mods button in the game menu. You'll see it. Runs fine right out of the box so to speak.

I had to type in the ROE key because it didn't autofill, and if you have ROE installed (not even run it) & don't type in the key the game will close.

also, from experience, if you put this on another computer (you know, you use two computers, completely legit & stuff) and you LAN them together, if it connected to the id servers & sees you are using the same CD key as the other computer, one of them will have it's cd-key files removed & you'll get a message that the key is in use. I'd suggest you backup your CD key files so you don't have to retype the keys in.

Even happens with the GPL engines I've tried. Haven't tried all of them though.

Does it happen with DHEWM3 too?
If II'm not mistaken is disregards CD keys and runs the co-op mode just fine.

I've tried some of the GPL D3 engines and sometimes get the same error, sometimes not. I don't normally use the GPL engines though due to the fact I want the tools too and, at the start, most engines removed the tools from the exe.

I can't make any sense what the conditions are for it saying one copy is legit or not. I've had D3 on three separate computers for years w/o any issue (coop, pvp, ctf, whatever) and then one day it hit me with that "duplicate keys" error. I even have it in 4 different install folders on my main PC and I've never had an issue if I tried running a listen server with one install & joined with a different.

It might have something to do with Bethesda/Microsoft deciding to enforce a CD-key check, or maybe it's because we use VPN's & one computer went to DC & one went to NYC and it thought that was funny.
