In C-evo, as generally in games of this type, the time a settler or engineer takes to perform terrain improvement tasks depends on the task and may also depend on the terrain. The in-game manual refers readers to a "terrain enhancement box". That box seemed to be missing from the version available in 2011. Version 1.2.0 has a "Terrain Enhancement" chart showing required movement points for various terrains, including some of the following:
- (under construction)
| Table of movement points |
EASY country without river | Easy country WITH river | ROUGH country without river | Rough country WITH river | Hill | Mountain |
|---|---|---|---|---|---|---|
| Road | 3 (includes desert) | 12 | 6 | 15 | 6 | 9 |
| Railroad | 6 | 12 | 21 | 12 | 18 | |
| Canal (not in Arctic) |
18 | 18 | 18 | 18 | 18 | N/A |
| Irrigation | 6 | 6 | (desert) 18 | N/A | ||
| Clear | N/A | N/A | 6 | N/A | N/A | |
| Drain swamp | N/A | N/A | 24 | N/A | N/A | |
| Farmland | 18 | N/A | N/A | N/A | ||
| Mine | 18 (Arctic) | 12 | 12 | |||
| Afforest | 18 | 24 | - | - | ||
| Fortress (manual says "6" but that is clearly wrong for some terrains) | 6 | 6 | 12 | 12 | 12 | 18 |
| Military base (manual says "6" but that is clearly wrong for some terrains) | 6 | 6 | 12 | 12 | 12 | 18 |
| Clean up pollution | 18 |
Miscellaneous[]
If you want to build a mine quickly on Arctic terrain, before you have engineers, you can build a military base (requiring Medicine) first, because it neutralizes terrain hostility letting you replace it with a mine without having to move off for recovery every few turns.
