The Machine is the Hub map of Dimension of the Machine. In this map, you will find the entrances to all of the expansions' Realms and their levels:
- The Realm of Machinists:
- The Realm of Blacksmiths:
- The Realm of Stonemasons:
- The Realm of Cultists:
- The Realm of Astrologers:
Once the Rune of each of these Realms has been discovered, the portal that leads to MGEND: Chthon's Vengeance will be unlocked.
As is symbolic of the Quake games, once you finish one episode/realm, you will be sent back here and will have your inventory reset back to default: Shotgun (Q1) with 25 Shells, Axe, and 100 Health (50 if playing on Nightmare difficulty).
