About this game
Introduction
Factor Y is a relaxing, large-scale, multi-planetary, mega factory automation game.Mine resources, craft new items and structures via recipes and generate your own, custom building blocks.
Expand your factory to span across multiple planets.
Demo
There's a demo of Factor Y which offers all the features of the full game except for the ability to load games.With the demo you can freely test the entire game and pick up where you left once you decide to get the full version (you'll have to manually copy the savegames folder).
Mining
Use miners combined with arms and belts to extract the planet's natural resources to feed your factory's ever-growing hunger.Processing
With the help of furnaces you can turn raw ores into plates.Which can then be used to craft items in assemblers with increasing complexity. Craft new structures such as belts and arms to further expand your factory.
Research
Unlock new technologies to increase your factory's throughput and size and to unlock more useful structures.You can later also unlock buffs that affect your current and future factories on all planets.
Modules
Use the planner feature to create custom blueprints.Which can then be turned into new buildings blocks (modules) for your factory. This way you can create new, custom 'assemblers' which may support any recipe.
You can even use your previously generated modules when planning new ones.
