The Pandemic Expansion brings the exciting pandemic mode to your table and is - of course compatible with all other modes in HE.R.O! There's 4 new diagnoses and a total of 10 new patients. You'll also find pandemic dice and pandemic markers, which are needed for the Pandemic Mode. Any new patient shows up? Roll the dice! if it's a green side, everything continues as usual. But if you roll a red side, the patient is infected! At the end of the round, every infected patient that didn't get treated will spread the infection to adjacent patients! So you can plan ahead and isolate them accordingly. With that not being challenging enough, if you treat a patient, the treatment station (or ICU, or OR,....) will stay dirty! Any new patient brought in there will automatically be infected. If you have no more "clean" areas, you automatically lose. —description from the publisher
