Quake: Dimension of the Machine

This is the second Quake expansion by MachineGames, released in 2021. In this one there are five short episodes with a central hub that you keep returning to. Each episode is two levels long, and is activating part of a giant machine in the hub level. After this there is a final boss level where you once again fight Chthon, the lava beast from the original game’s first episode.
