Ecoterrorists can nano-attack, which destroys all city improvements in the infected city. Any city trading with the infected city has a 20% chance of becoming infected in the next turn. The Ecoterrorist has a 25% chance of success. However, if the attack fails the Ecoterrorist also has a 25% chance of being caught and killed. The nano-attack costs 4,000 gold.

Starting in 2112 Ecoterrorists programmed nano-viruses, mechanized termites, to feed themselves on the equipment and resources of factories, refineries, and other critical production targets. Though programmed to avoid living targets, nano-viral agents destroyed the infrastructure and economies of cities, taking down buildings as well as forcing people out of work. Environmentalists recognized this side effect as the price of a green planet.
