To survive across all three chapters in War Hospital, players will have to effectively manage resources between crafting new medical and food supplies and improving different parts of their hospital to survive the onslaught of battles in World War I. With four separate trees of unlocks in the improvements tab, players can feel a little overwhelmed when deciding which improvements to unlock first. We will break down every improvement, highlighting the priority unlocks in each tree, to help players set up a solid base of operation behind the frontlines trenches in France.
