Quarantine: First Aid Expansion
Welcome back to the hospital! We're sorry that you were unable to stop the spread of Graysles. In Quarantine: First Aid Expansion you'll receive some helpful tiles: the Morgue, which is one way to stop Graysles, and the Public Relations Office, which will ensure that everyone knows that the last disaster in your hospital wasn't really your fault.
