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.

Improvements in War Hospital are split across four categories, Healing, Housing, Production, and Scouting. Players will want to focus primarily on the Healing and Production trees as they offer upgrades that increase overall hospital efficiency, reducing the time needed to create new resources or complete operations.

To start an improvement, open the improvement menu and select the desired unlock. Players will need the required raw materials and war permits to begin the upgrade - be careful not to completely deplete raw materials or you will be unable to produce medical and food supplies. After selecting the improvement, assign up to four engineers to work on the upgrade, hit assign to confirm the designations, exit the menu, and allow the engineers to work. Players will hear an audio confirmation when the engineers reach the construction site, and players can monitor the improvements construction progress in the top left of the HUD.

Healing

War Hospital - Improvements - Healing

The healing improvements focus on the patient healing process's four main areas: the Casualty Clearing Station (CCS), the Advanced Dressing Station (ADS), the Operating Wards, and the Patient Rehabilitation Center. Players can improve hospital effectiveness by building this improvement tree, expanding the Operating Ward to handle chemical and trauma procedures, unlocking Special Operations with reduced operation time, and increasing the chances of an operation simplification.

Players will want to unlock the two additional wards by the attack on Jun 14th, as after this battle players will begin receiving trauma patients at the CCS. It is smart to consider having both wards unlocked at this point (if not sooner), as players will want to be able to access the Medical Drip and Specialistic Light System improvements which affect multiple wards.

6 Strategy Games That Have No Combat

Strategy games often involve engaging in open war with rival nations, but these games forgo combat in favor of strategic city planning and building.

Production

War Hospital - Improvements - Production

The Production improvement tree allows players to upgrade the efficiency of the hospital, offering improvements that affect production costs and speed. By advancing the Production tree, players can create a self-sustaining hospital that only needs raw materials delivered by the train to survive, using engineers to craft all medical and food supplies.

Since players can reduce improvement speed, medical materials production cost, and daily ration requirements, players will want to focus on upgrading the Production tree first. Players will also find that the Production tree upgrades require lower materials, making them easier to attain earlier in the game.

Players will want to consider upgrading the warehouse at least once in Chapter 1, and again before the end of Chapter 2, or immediately at the start of Chapter 3. As the game progresses, players will receive patients in larger volumes, and players will need to stock up on medical supplies for doctors to start operations on patients.

7 Strategy Games With The Best Base Building

Strategy games come in a few different shapes and sizes, but what makes the following special is their unrivaled base-building features.

Scouting

War Hospital - Improvements - Scouting

After players progress through the first few attacks in Chapter 1, there will be a communication from Colonel Angus about setting up a scout team to run missions in the area surrounding the hospital. Once players receive this notice, they can begin working on the Scouting improvement tree.

By upgrading the Scouting tree, players can increase the number of teams available, and reduce the time needed to complete missions - as scout missions are a great way to receive war and staff permits, improving the scouting tree can help players quickly grow their hospital with additional personnel and improvements.

Prioritizing Improvements

When deciding on improvements, players should always consider an upgrade in the Production tree first, followed by an upgrade in the Healing tree. While operational success and efficiency are important, players will not be able to survive for long if they neglect the Production improvements, finding themselves in a position where medical supplies are unavailable, raw materials are unavailable, and in worst cases, deliveries are unavailable as well. Players must establish a solid construction base for efficiently producing supplies at the Pharmacy or Engineering Depot (reducing time and raw material costs is crucial). Additionally, by enhancing the Engineering Depot, players will reduce the construction time required for all other improvements.

Be sure to upgrade operating wards and housing if no slots are available to hire a type of personnel as players will occasionally get an offer from a VIP for them to join the hospital staff, players must have space in the staff lodging to hire the VIP. Upgrades in the scouting tree are least necessary for success, just take the scout tent upgrades when prompted by the NPC's in-game, and upgrade the tree if extra war permits are available. If players are unable to complete side tasks as they spawn and are struggling to generate staff permits, improving scouting abilities can offer players a way to quickly generate staff permits by completing missions. If players feel their staff is too small, focus on scouting missions to acquire the permits to hire more personnel.
