Beyond the Sword contains the expected smattering of new units, buildings and actual civilizations. There are also a number of gameplay tweaks and some improvements to a few of the advisor screens. But wait! There's more! Espionage has received a major upgrade while the end-game has been enhanced by the addition of Corporations, a sort of modern day equivalent to Religion. Riding piggyback are also a number of mods, some of which, like the UFO-inspired Aftermath, use the game engine in wholly unexpected ways.
