Modding#

Before modding, editing, or deleting anything, be sure to keep original copies in a separate folder.

Adding Characters & Vehicles#

Almost every unused character and vehicle can be modded back in by adding them to the CHARS\COLLECTION.TXT file. The filenames of them are listed in the specific subpages.

A step by step guide:

Close the game if you have it running.
Read COLLECTION.TXT. Just so you can get an idea of how its formatted.
Find the specific category in it.
Add one of these example lines to the bottom of the category list, under the existing characters/vehicles, but with replacing the name and cheat code to the one you want.

Characters#

In this Character example, the CIVILIAN_BUDDY character will be added under the SERVICE category. ("cat 10")

collect Civilian_Buddy                 token  buy_in_shop        100   cat 10     customiser_parts                                     cheat_code buddyc

So, if you wanted to get the COP_INTERNHONEY character too, you add this line:

collect COP_INTERNHONEY                token  buy_in_shop        100   cat 10     customiser_parts                                          cheat_code honeyi

Vehicles#

In this Vehicle example, the Bog will be added under the BIKES category. ("cat 17")

collect Novelty_Bog                    token  buy_in_shop        100   cat 17       group 0                                   cheat_code toilet

So, if you wanted to get the NOVELTY_BUFFER vehicle too, you add this line:

collect Novelty_Buffer                    token  buy_in_shop        100   cat 17    group 0                                   cheat_code buffer

Any 6-digit code will work because the last 7th digit in the cheat code menu can be changed to an empty space.
Save the COLLECTION.TXT.
Open the game.
If all goes well, once you enter the cheat code, they will be added to your Disguise Booth menu and/or Vehicle spawn menu.

Replacing Characters & Vehicles#

Some character/vehicles weren't complete and can't be added via a code.
In those cases, you can replace the files of a used character/vehicle with an unused one, and simply rename it. This comes with the drawback of replacing existing content, so make sure it's a character/vehicle you don't care about.

This example guide will replace the POLICE_SQUADDIE with the unfinished FARM_DEVOURER vehicle.

Go to the CHARS\VEHICLES\POLICE\POLICE_SQUADDIE folder.
Move all the files to a separate safe folder.
Copy the files from CHARS\VEHICLES\FARM\FARM_DEVOURER.
Paste all the files to the CHARS\VEHICLES\POLICE\POLICE_SQUADDIE folder.
Rename the filenames from FARM_DEVOURER to POLICE_SQUADDIE.

Custom Minifigure Textures#

All the character textures and models are under the CHARS\MINIFIGS\SUPER_CHARACTERS folder.

Minifigure textures can be replaced with custom textures by using programs like GIMP or Paint.net. Be sure to export your texture as a .DDS, and rename it to .TEX.
