Broken Earth

The Broken Earth scenario is one of the two scenarios available in the Dark Skies DLC. It begins in the year 2112, one hundred and fifty years into an alternate timeline where the Cuban Missile Crisis led to a nuclear exchange that destroyed much of human civilization. It includes a number of adjustments to the setup of the game to emphasize the post-apocalyptic nature of the setting, most of which serve to increase the role of terrestrial warfare (especially in the early game).

Major changes include:

• Nations are typically much smaller and more equal in power, with relatively few peaceful claims but large numbers of hostile claims.
• Armies are much cheaper to build and maintain.
• No nation begins with nuclear weapons or any progress towards unlocking them, and there is a global -95% penalty to IP investments into nuclear weapons research.
• Each faction will receive a powerful Playing From Behind project early in the game, which gives significant faction-specific bonuses and penalties.
