I have no idea what any of these are LOL
Dawn of the Machine is available as a free update for Quake owners on XBOX Series X/S, XBOX One, Microsoft PC Store, Game Pass, PC Game Pass, Steam, PlayStation 5, PlayStation 4, Nintendo Switch 2 (via backwards compatibility), and Nintendo Switch versions of Quake.
I do still have my Quake CDs...
Same.
Weird to see a DLC for a game that's older than Steam. Would have been more interesting if they released the WADs or whatever that you could play on the open source version of the game. (All of this is interesting in light of MS's recent hallowing of their game studios.)
When Quake was popular, CDs were far and away the most popular install method. They're locking a lot of OG owners out (unless they're hoping to drive a trickle of $4 Steam sales).
These are out for the enhanced release all owners of Quake on Steam/GoG got for free when Nightdive remastered Quake I/II.
Unfortunately they break the limits of the original game engine and usually require something like Darkplaces[0] to run. Although I highly recommend darkplaces for even players of the original Quake because the QoL improvements are nice.

I figured as much. Some of the addons for the 'modern' Quake seem to really stretch it way beyond anything we saw out of the original engine.
Also love that there is a 50% chance that you can crash a Ps4/Switch just loading a level with the Slave Zero mod that they provide. They are pushing it fairly hard with that one.
They're called "pak"s for quake :)
It's been so long since I've put the CD in, I forgot.
Quake launched 2 full years after Playstation 1, so I find it somewhat unlikely you've never heard of a Playstation. And if you have it on CDs you must have played it on PC with Microsoft Windows, so I'd assume a Microsoft PC Store should at least let you guess what it is.
Quake was a DOS game.
It was actually both in one executable. Pretty neat. But I will agree that OP might have played it in Microsoft Dos on a PC, so the original point still applies.
