Is there any single player or coop modules available now?
I’m sure there’s plenty but right off the top of my head, “Ghost Stories” comes to mind.
For coop modules you have Pandemic, Yggdrasil !
For single player … are you looking for Wargames or Eurogames or Print & Play games ?

Intruder is playable solitaire (2-player too).
