A listing on the Steam App database from Valve suggests that the turn-based strategy title Civilization V is set to get access to a new expansion, called One World.
A listing has been spotted by a user on the official 2K forums
and the development team has refused to either confirm or deny its existence, which is typically a good sign that Firaxis is actually working on something new for its core strategy series.
No official details are offered on what players might get from One World.
Civilization V has changed the franchise forever because it has introduced hexes in the place of squares and a new rule that allows just one military unit to occupy one area at a time.
Firaxis has launched an expansion called Gods & Kings, introducing religion and new mechanics to the game, and another expansion is a plausible idea.
