Caveman2Cosmos is a community mod that add new features, gameplay, and content to the Civilization 4 experience. It is the most expansive Civilization 4: BTS mod to date with almost daily updates since November 2010. It is the spiritual successor the The Civilization 4 mod Rise of Mankind and its addon A New Dawn, and combines the work of over 100+ past and present modders to create a mod to "rule them all". It is currently being developed by StrategyOnly Productions with a modding team made up of prominent members of

Caveman2Cosmos introduces a massive amount of new content with massive customization to Civilization 4 : Beyond the Sword. From the the discovery of controlled fire in the Prehistoric Era to the spaceships of the Galactic Era this community mod is perfect for the player who craves very deep strategy but is still enjoyable to the more casual player. Be warned, with this much content this mod may take almost 100 hours or more to win a single game. This mod is evolving on a weekly basis and new features are added all the time!

Good news, the new "Graphics paging" option saves about 30% of RAM memory usage (with bigger maps, more RAM saving), and it should remove virtually all MAF errors.It replaces the Viewports system. This system can be activated in BUG Options screen. It should be auto-activated by default. See Version 33 Changelog under the Features Tab above for more details.
