What Is Last Asylum Plague
A mysterious plague spreads across the world, and you take the role of a plague doctor. The Sanctuary is your base: you treat patients, craft herbal remedies and expand the wards, while survivors gather Grain, Timber and Herb from outposts in the wild. Heroes defend the base against the Rat Swarm, and elite squads of heroes later reclaim plague-ridden towns on the world map. The stores list the game as a strategy and simulation title for ages 12+.
WISENESS GAME ONLINE INTERNATIONAL LTD developed the game, 37GAMES GLOBAL publishes it, and it came out on February 11, 2026 on the App Store. The App Store shows 4.78 stars from 42,355 ratings, and Google Play shows 4.4 stars from 372K reviews.

Beginner Tips
The first days decide how fast the base grows, and three habits help most.
- Follow the chapter quests and keep a build queue running. The beginner guide sets the order for the first 24 hours and the first week.
- Raise the Sanctuary first, because it caps the other buildings. Check what the next level asks for on the Sanctuary page before you spend resources.
- Enter the working codes from the list above, then look at the upgrade guide for what to research and build next.

The updates page follows the versions and the larger additions such as Kingdom War and Era of Revival.
