Frequently Asked Questions
Doomsday Lord (末日之主) is a GPS survival game for iOS. After downloading, grant location permission and tap "Start Exploring" on the map screen. Walk around your neighborhood to discover ruins, collect resources, and claim territory.
Location is the core of Doomsday Lord's gameplay — it's how you explore the real world, claim territory, and discover nearby ruins. Location is only active while you're exploring. We never track you in the background when the app is not in use.
On the Map tab, tap "Start Tracking." Walk the perimeter of the area you want to claim — your GPS path draws a polygon on the real map. When you close the loop (return near your starting point), the territory is claimed. It must not overlap with other players' territories.
Start exploring, then walk toward a POI (Point of Interest) such as a hospital, gas station, or factory. Once you get within range, a popup appears letting you "Scavenge Now." The reward tier (Bronze → Silver → Gold → Diamond → Legendary) depends on your total exploration distance in that session.
Territory claims can fail if: (1) the area overlaps with another player's existing territory, (2) you moved too fast (driving instead of walking), (3) your path didn't form a valid closed polygon, or (4) your health/vitals reached critical levels during tracking. Try walking a smaller area in a different location.
Doomsday Lord subscriptions are managed through your Apple ID. To cancel or modify: go to iOS Settings → [Your Name] → Subscriptions → Doomsday Lord. Your subscription remains active until the end of the current billing period after cancellation.
Check your in-game Mailbox — purchased items are delivered there. If the mailbox is empty, tap the "Restore Purchases" button in the Store section. If the issue persists, contact us at 1614103587@qq.com with your Apple purchase receipt.
In the app, go to Profile → Settings → Delete Account. This will permanently remove your account and all associated data. Alternatively, email us at 1614103587@qq.com and we'll process the deletion within 7 days. Note: account deletion is irreversible.
Common Issues
🔴 App won't load
Force-close and reopen the app. Check your internet connection. If persistent, uninstall and reinstall from the App Store.
📍 Location not working
Go to iOS Settings → Privacy & Security → Location Services → Doomsday Lord and set to "While Using App." Ensure Location Services is enabled globally.
🗺️ Map not displaying
The map requires an internet connection to load tiles. Check your Wi-Fi or cellular data. Moving to an area with better signal usually resolves this.
⚙️ Exploration stops suddenly
Exploration automatically stops if: your vitals (health/food/water) reach critical levels, you move too fast (vehicle speed), or you stay in one building too long. Check your vitals and keep moving on foot.
