For new players that would like to join the Project Hospital community or are considering giving Project Hospital as a gift. If you'd like to buy Project Hospital with all the DLCs that add new departments, there's a new bundle available that will allow you to get the content at once and will add a nice little 12% discount even when the game or DLCs are on sale at the moment.
