Is it possible to transform terrain into glacier?
In Freeciv, is it possible to transform land tiles into glacier? I have researched the "explosives" technology, which allows the building of engineer units. However, I don't see any options in an engineer's "Work" menu for transforming a tile into glacier. I want to transform some land tiles into glacier to prevent enemies from getting resources from those tiles.
No (and doing so would be a very inefficient way to deny resources).
You can transform a tile from a glacier to tundra but no tiles transform (or irrigate or mine) into glacier.
This image shows what happens to terrain when transformed.
