Arkham Horror
Do expansion monsters get added to older base-game scenarios?
Two forum players read the expansion instructions this way; it is an inference, not a stated rule.

Yes, most likely. The 'Using This Expansion' instructions say to use the whole expansion, so its monsters join the monster deck wherever a scenario calls for them by trait, even in base-game scenarios. Players read this as intentional, but no official ruling says so.
