Survivors will keep working even when you are away. This means you can claim offline rewards whenever you return to the game.

The offline report is divided into three sections:

- Offline Time: How long you have been away from the game
- Offline Rewards: The resources your Survivors produced while you were away (the resources will stop accumulating after 2 hours of offline time, or 4 hours if you have activated the privilege)
- Survivors Report: The number of Survivors that died or were cured while you were away
