The update version 2.3 for Doom: The Dark Ages enhances the Ripatorium feature, refining the wave-based mode that allows players to create their own demonic encounters. It includes rebalancing of combat encounters with adjustments to enemy presence, and introduces a new option for the "Brink of Death" feature, allowing players to modify its impact on survival rates. The update aims to foster community engagement around the Ripatorium despite the absence of the Snapmap system from Doom 2016.
