About the Game

Guiding a small group of "agents", you will gradually discover a Lost World, the seemingly simple graphics of which conceal its hidden complexity...

You will learn to move in it, to understand its physical properties, to accumulate sufficient stocks of materials, to build structures, machines and vehicles, to engineer various types of power plants to fullfill your growing needs for energy, and to search, sometimes even in the fog of war, for the enemy that your destiny requires you to defeat...

72 built-in levels + unlockable User Level Editor

Warning: despite its basic graphics, this engineering puzzle game has a high level of complexity that reserves it for particularly experienced players. It takes about 20 levels to start getting a feel for some of the mechanics available, and you'll discover new ones until the end. The best players will take at least forty to sixty hours to complete the game.
