Expand your hospital's depth with new underground modules and quirky upgrades.

This is the last extension for Clinic Deluxe Edition released for the non Essen fair in 2020.
It contains:
- 4 New player boards, called basement board printed both side Normal/Expert
- 9 New very special Double tiles printed both side
- A set of Rules

As a side note: Clinic Deluxe Edition - 2nd Extension and Clinic Deluxe Edition - 3rd Extension have been skipped by the designer because of lack of play testing during the lockdowns. They will be released later in 2021-2022.

So Clinic Deluxe Edition - 4th Extension will be the last expansion and will end the series.
