Scorched Earth, the practice of destroying anything useful to an enemy, can make even the most secure opponents feel less secure, and get them to divulge information easier. The technology involved with this halves the cost of hiring spies and increases the time a player with a relic monopoly and/or a monument built must hold it to win the game

A scorched earth policy is a military strategy or operational method which involves destroying anything that might be useful to the enemy while advancing through or withdrawing from an area. Although initially referring to the practice of burning crops to deny the enemy food sources, the practice may be carried out by an army in enemy territory, or its own home territory. During the Hundred Years' War, both the English and the French conducted chevauchée raids over the enemy territory to damage its infrastructure. Other, more modern examples include Sherman's March of 1864 during the American Civil War and German and Soviet applications of this on the Eastern Front of World War II. Scorched earth tactics are officially outlawed by the Geneva Conventions, but like the ban on the usage of landmines, it is ignored in many cases.
In addition to the other effects mentioned above, whenever a player researches Scorched Earth, a chat message is sent by the game saying "(player name) mocks your puny achievements. Relic and Monument victories now take longer!"
