Before you start doing anything, you have to know how to call Factorio in-game console, because it's only place where you will be doing all changes.

Warning, when you are using any Lua based commands, you'll possibly get some errors, even if you not messing with syntax. So, before changing anything, DO A BACKUP of you MAP. Some of changes you'll be doing are really difficult or even impossible to revert!!

To work with console commands, when you creating a Multiplayer server, you have to set "Alow commands" to "True". If you did this, or just playing\testing in single-player, press a "~" on your keyboard. From here you can write messages to other players, commands, or even parts of Lua script. You can check which commands are available for you by writing "/h" command in console, and pressing 'Enter' on you keyboard. Take a look on "/c" and it's description, because everything in this guide will be done with this command. The main goal of this command is allow you to execute parts of Lua scripts (most factorio mods wrote in Lua)

Because all the commands described in this guide, are actually small lua scripts, you have to write them in console, with '/c ' prefix, like this: Not all described commands will answer with some response. Naturally, you will get response if 'print' keyword exists in command body.

Before doing anything, let's gather some useful info.

To find out in which team you are currently in, do:
To find out which teams are already existing in game, do: If you didn't changed anything before, you'll get 3 teams:

• 'player' -- default team for all new players who joins the game, including you.
  
• 'enemy' -- default team for aliens, their hives, bitters, spitters etc.
  
• 'neutral' -- empty team by default, but you can join it to build some infrastructure accessible for members of all teams, including currently not existing.

I have to warn you that each team isolated with it's own research progress, not just power and production systems. And each building created by the member of one team are inaccessible by the members of other teams (except 'neutral' built-in team)

So let's prepare some teams for our players.

To create a Team with name 'Team1':
Warning, this new team will be an enemy to all other teams including default 'player', and except 'neutral' team and all their building including turrets.

To remove team 'Team1', merge it with default team 'player':
Notice: Current versions of factorio has the chance that game will crash if there're some members existing in the merged team.

To assign a player with name 'Player1' to the team 'Team1':

To remove a player with name 'Player1' from the team 'Team1, assign him\her to the default 'player' team:

You can make you new team neutral to the over teams including default 'player' team, so your defence will not attack them, and their - you:
But this action DOES NOT GRANT you access to their inventories and machines!

In this section we well talk about how to transfer some existing buildings and technologies from one team to another.

Because the transfer mechanics based on region scan, you have to determinate rectangular region in which changes will be made. To do so open the debug console, by pressing 'F4' on your keyboard, switch to the 'allways' tab, and check 'show_detailed_info' checkbox. (I also recommend you to check 'show_tile_grid' to turn on map grid, which allow you more easily understand block and chunks of the map). After checking needed options, press 'F4' again. You'll see some new info at the top left corner of game window. Take a look at the first string 'Cursor'. From first pair of braces you can get the coordinates of your cursor on the map. So, imagine a rectangle, which will cover all buildings required to transfer to another team. Put the cursor on the top left and bottom right corners of that imaginary rectangle, and write down cursor's coordinates (for my example it will be -10 -10 and 10 10, to form 20x20 rectangle)

Now we can scan which entities (players, environment, buildings, machines) are exists in the designated region: If this command respond to you with names of required to transfer objects, you can do following to actually transfer them to the 'Team1':
If you already played some time as a member of the default team 'player' and researched some technologies, and than switched to the specific team like 'Team1', you will lose all of you researches and explored map, because each team isolated with it's own research progress, not just power and production systems. First, I recommend you to finish current research of you old team, if it was 'player' team, do: , than you can list all researched technologies of you old team:. If you're satisfied with result, you can copy all of them to your new team, like 'Team1' with:

In this optional section, I will tell about two not really useful but fun commands.

This command will allow you, as admin, to freely give player 'Player1' 10 iron plates:
Unfortunately, I can't say where you can get name of all items in a factorio, so I suggest that you can use English name of items, where ' ' (space) replaced with '-' (minus)

This command will allow you spawn 'Assembly machine' building, tier 1, with presetted recipe (assemble 'iron-stick') and bound to your team: Take a look on the 'position' parameter. This is coordinates, where you building will be spawned. With this command you can also build on the water tiles.

With this command script you can create some flying text, which will be visible for several seconds to everyone who working near designated coordinates: To change my text, just replace the sting inside quotes after 'text' parameter, with yours.

With this command you can recolor yourself:Will recolor your character into pure red. To ajust your color change values for "r" (Red), "g" (Green), "b" (Blue), "a" (Alpha). All values could be only between 0.0 to 1.0

That's all for now. If I discover some more, I will update this guide. So, please subscribe ;)
