The fourth expansion for Funcom's Science-Fiction MMORPG revisits player-versus-player combat. Players fight for control of the new space stations to get access to orbital lasers and bombing ships. New vehicles in the shape of giant mechs are added to the game that provide another dimension of tactics to PvP combat, and upgrades for the vehicles are available through a newly introduced research system.
New dungeons allow players explore the insides of the Alien Invasion motherships, fight new alien monsters and gain access to alien technology.
Like previous expansions, Lost Eden adds a wide range of new weapons and armor, among them missile launchers to combat the new mechs.
