Expeditions
From Project Rebearth
Expeditions are missions in Project Rebearth that allow players to explore unclaimed territory on the map. Each expedition covers a player-selected area and costs 
Food, 
Knowledge, and population based on the size of the area. Upon completion, expeditions yield 
Scrap and a random basic resource (
Wood, 
Stone, 
Earth, or 
Glass).
Costs
[edit]Expedition costs scale linearly with the area selected. The following table shows costs per 1,000 hectares (10,000,000 m²).
| Cost | Per 1,000 hectares | Notes |
|---|---|---|
| Duration | 1 day | Base duration before distance bonus |
| Population | 0.03 | 3 people per 100,000 hectares |
| Knowledge |
10 | Paid upfront when launching |
| Food |
100 | Consumed during the expedition |
An additional 1 hour is added to the expedition duration for every kilometer between the expedition area and the player's settlement. This distance bonus means nearby expeditions complete faster than distant ones.
Yields
[edit]Expeditions guarantee base yields that scale with the area explored. The following table shows yields per 1,000 hectares.
| Yield | Per 1,000 hectares | Description |
|---|---|---|
| Scrap |
3 | Old-world remnants found while exploring |
| Basic resource | 15 | Random Wood, Stone, Earth, or Glass gathered en route
|
Affected By
[edit]| Source | Effect | Description |
|---|---|---|
| Science League | Expedition cost -20% | Reduces all expedition costs by 20% |
Strategy
[edit]Expedition costs and yields both scale linearly with area, so the resource return per hectare is constant regardless of expedition size. The main variable is the distance bonus on duration: nearby expeditions are significantly faster than distant ones. Players looking to maximize Scrap income should prioritize large, nearby areas to minimize idle time.
The Knowledge cost (10 per 1,000 hectares) can be substantial for very large expeditions, so players should ensure they have adequate Knowledge reserves or a strong research economy (University, Museum) before launching major expeditions.
Settlements in a Science League alliance benefit from a 20% reduction in all expedition costs, making them well suited for frequent exploration.
