- Echoes of the Past throws out that steady, measured bleeding of doom in favor of a new sort of chaos. A panicky, paranoid, "what will the encounter deck reveal next?" sort of chaos. Your doom won't march forward at any predetermined pace; instead, it will collect doom in fits and starts as you come across enemies like the Seeker of CarcosaÂ (Echoes of the Past, 144) as they dart the Society's different rooms and hallways.
- This new mechanic does a couple of things in the scenario. It allows you to play with an agenda deck that can advance in a single round or not at all. It demands that you deal swiftly with all of the Cultists you encounter in order to prevent them from collecting doom. And it personalizes the effort no longer are the forces of the mythos proceeding apace somewhere in the hazy distance; they're in your room, or down the hallway, or scuffing furniture and bookshelves along the floors above you!
In the meantime, you can rest assured that the scenario is still going to force you to make the most of every action. After all, each agenda step offers only a very narrow margin for error. And, in the end, if the Cultists find their clues before you? It's not clear exactly what the changes will mean, but your whole campaign will shift.
