Go to the extremes of civility with the Survival Pack for Sid Meier's Civilization Revolution! Includes three map-based scenarios: Ice Age, Global Warming and The Eye. In The Eye, keep your peepers peeled, as this scenario features faster units, bonus starting technologies, and extra naval support. In Global Warming the seas have risen, the continents have sunk beneath the waves, and things are about to get ugly. Raging barbarians, scarce resources, and creeping deserts have decimated the planet and it is up to you to bring order to a world in chaos. In the final scenario, the world is caught in the frozen grip of the latest Ice Age. Navigate frosty channels and keep an eye open for raging barbarians - they seem to be out in force.
