At any one time, each of the three PlanetSide servers host thousands of players fighting a persistent war on foot, in ground vehicles or in the air across desert wastes, icy mountains, lush forests or dank swamps. The gameplay is simple: each faction must attempt to capture as many facilities as possible on the surface of the planet whilst denying them to their enemies. There are many strategies and opportunities for tacticians to divert the flow of battle and learning the intricacies and depth of the game can take many months. The player controls his chosen character from a first-person perspective and can travel about the vast environments on foot or in one of the many available vehicles. Combat is fast-paced and does not suffer from the 'hands-off' feel of many other Massively Multiplayer Online Games.
On October 27, 2003, SOE released Core Combat, the first expansion for PlanetSide. As of 2004, the game is actively supported by Sony Online Entertainment and new content and patches are released about once per month.
