These scripts arrange the continental land and open sea into various configurations. Maps can be randomly generated through scripts, some of which were added with the Gods & Kings and Brave New World expansions. However, there are some map scripts, such as Inland Sea, that do not feature wraparound with hard borders on all four edges. In most cases, the map will be cylindrical with wraparound on an east–west axis, with impassible ice caps at the northern and southern edges. The map consists of a rectangular set of hexagonal tiles, and comes in six sizes. Most scenarios use premade maps, but other types of games allow players to choose their own map script and let the game generate a world for them. The map is the world on which a game of Civilization V takes place.
