The Infirmary in Whiteout Survival is your settlement’s medical hub, vital for keeping your survivors healthy and ready for combat. Unlike other buildings that focus purely on resource production or military strength, the Infirmary serves as your primary healing center, allowing injured heroes to recover faster and return to their duties.
This guide covers essential functions, upgrade priorities, and strategies to maximize its effectiveness in your base development plan.

Healing Troops
When your troops return from battle with injuries, they automatically enter the Infirmary’s queue for treatment. The healing process requires both time and resources, with more severely wounded units demanding longer recovery periods.
Upgrading your Infirmary increases both its capacity and healing efficiency, allowing you to process more injured troops simultaneously and get them back to active duty faster.
For commanders looking to optimize their military operations, prioritizing Infirmary upgrades becomes crucial, especially as you engage in more frequent or challenging combat scenarios.
A well-developed medical facility can be the difference between maintaining combat readiness and struggling to field adequate forces for defense or resource gathering expeditions.
Batch Healing (Micro Healing):
One of the most efficient ways to manage your healing resources is through Batch Healing, also known as Micro Healing. This technique allows you to heal multiple troops simultaneously while optimizing your healing speedups and resources. Rather than healing all troops at once or leaving them to recover naturally, micro healing lets you strategically heal smaller batches of troops, maintaining your combat readiness without depleting your medical supplies.
When your Infirmary is filled with wounded soldiers after a tough battle, consider healing them in smaller groups instead of using your speedups on the entire batch. This approach preserves your healing items for when they’re truly needed and ensures you always have some troops available for defense or resource gathering.
Enlistment Office:
This critical facility determines the quality and quantity of heroes available to your settlement, making it one of the first buildings you should focus on developing as your base expands.
With each upgrade to your Enlistment Office, you’ll gain access to higher-tier heroes with improved stats and abilities, significantly boosting your combat effectiveness against both environmental threats and rival settlements.
Loyalty Tag
It can dramatically improve your resource collection rates, strengthen your defensive capabilities, or even help your Infirmary heal wounded troops faster.
How to get Loyalty Tag:
To earn a Loyalty Tag in Whiteout Survival, you’ll need to visit the Infirmary and complete specific tasks. The Infirmary serves as a hub for alliance-related activities, including tag distribution.
By consistently participating in alliance events, donating resources, and helping fellow members, you’ll gradually build the loyalty points needed to claim your tag.
Remember that the Whiteout Survival Infirmary tracks your contributions automatically, so focus on being a valuable team player rather than just grinding for the tag itself.
