Guide a small team of agents through a Lost World whose deceptively simple visual presentation conceals a deeply layered environment. Learn how the physical properties of this world work, gather materials, construct structures and machines and vehicles, build power plants to meet growing energy needs, and search — sometimes through fog of war — for the enemy that the player's role in this world requires defeating. Seventy-two built-in levels, plus an unlockable level editor and experimental LAN multiplayer.
