# Factorio

## Where is the settings page?

The [player settings page for this game](../player-settings) contains all the options you need to configure and export a
config file.

## What does randomization do to this game?

In Factorio, the research tree is shuffled, causing certain technologies to be obtained in a non-standard order. Recipe
costs, technology requirements, and science pack requirements may also be shuffled at the player's discretion.

## What Factorio items can appear in other players' worlds?

Factorio's technologies are removed from its tech tree and placed into other players' worlds. When those technologies
are found, they are sent back to Factorio along with, optionally, free samples of those technologies.

## What is a free sample?

A free sample is a single or stack of items in Factorio, granted by a technology received from another world. For
example, receiving the technology `Portable Solar Panel` may also grant the player a stack of portable solar panels, and
place them directly into the player's inventory.

## What does another world's item look like in Factorio?

In Factorio, items which need to be sent to other worlds appear in the tech tree as new research items. They are
represented by the Archipelago icon, and must be researched as if it were a normal technology. Upon successful
completion of research, the item will be sent to its home world.

## When the engineer receives an item, what happens?

When the player receives a technology, it is instantly learned and able to be crafted. A message will appear in the chat
log to notify the player, and if free samples are enabled the player may also receive some items directly to their
inventory.
