From the release:
Prepare for a battle with the sea itself. With the threat of flooding from North Sea storms and overflowing rivers constantly looming over the Netherlands, you and your team have been chosen to construct a modern hydraulic system that will keep the ever-encroaching waters at bay. To succeed, you’ll first need to control the flow of water and keep it from spilling too far across the countryside. But storms are brewing and the sea is restless. Gather your team and fight the tide. Pandemic: Rising Tide is on sale now!
