Its maximum size is 3 and its vision radius is 2. Each building of an Industry tile has 3 hitpoints. When destroyed, an Industry tile becomes a Rubble tile and emits 1 Gas.
At night, each Industry tile generates three income per powered building it has. An Industry tile will only gain power at night if its surroundings are sufficiently populated; the total sum of power of surrounding City tiles must be greater than its current power. Unlike City tiles, Industry tiles do not automatically gain a building if they would have more power than their current size; instead they must be manually upgraded. An Industry tile that is occupied by an enemy unit does not generate income and does not gain power.
