### **Core Gameplay & World**
* **The Oasis:** You play as the "Boss" tasked with transforming a nuclear-scarred wasteland into a thriving civilization. Central to your survival is the **Water Center**, which must be connected to all buildings to maintain sustainable temperatures and resource production.
* **Base Management:** You build essential infrastructure like **Pumping Wells** (water), **Canneries** (food), and **Iron Mines**. Rescued survivors are housed in **Cabins** and can be assigned to work in these facilities to boost output.
* **Expedition Mode:** Unlike the map-based strategy, this mode features **turn-based combat** where your team of heroes takes on waves of enemies. Completing these stages is the primary way to earn building materials and upgrade scrolls.
### **Key Features**
* **Hero Gacha:** You recruit elite survivors, each with unique combat skills. Recent 2026 additions include red-star rating tiers to simplify identifying high-power characters.
* **Military Training:** You train specialized troops like **Rangers** to defend your base and conduct raids.
* **Exploration:** You dispatch scouts to clear the "Fog of War" on the world map, uncovering hidden riches, abandoned buildings, and enemy threats.
* **Alliances:** Joining an alliance is vital for "Region Conquest." Allies provide speed-ups for construction and allow you to participate in massive multi-player rallies.
### **April 2026 Updates (Version 1.6.3)**
* **Imperator Titles:** A new rule clarification ensures that if a defending region wins a conquest, their current *Imperator* (top leader) retains their title.
* **Rally Tier Limits:** New auto-join limits for rallies have been added, allowing players to filter for specific troop tiers more effectively.
* **Optimization:** The "Speedup Selection" interface has been improved so that receiving Alliance Help no longer resets your manually selected number of speedup items.
### **Technical Details**
* **Platform:** Available on Android, iOS, and **Windows PC** (optimized for 4 CPU physical cores and 8GB RAM).
* **Rating:** Rated **12+** (Teen) for realistic violence and guns.
* **Monetization:** Free-to-play with in-app purchases. The game uses **Fuel** as its primary premium currency for building upgrades.
It is particularly well-suited for players who enjoy the "stat-heavy" progression of traditional SLGs but want a more atmospheric, survival-focused narrative.
