This year is the 30th anniversary of the launch of the original Quake by id Software, if you could believe it. To commemorate that, publisher Bethesda has released a new campaign chapter for the game, titled "Dawn of the Machine."
This is part of a series of new campaign chapters, all developed by MachineGames "in collaboration with id Software." MachineGames is best known for making the games in the relatively recent Wolfenstein reboot series, as well as Indiana Jones and the Great Circle. The Quake maps are made by a team dubbed "Quake Club," which includes several MachineGames employees who work on Quake maps in their spare time.
The ambition and scope of some of these maps is beyond what was typical for Quake maps back in the late '90s, thanks in part to the team's use of Trenchbloom, a newer map editor that works well on modern systems and is easier to work with and more capable than what folks were using in those days.
