To enable the console in Postal 3 search for the files config.cfg and config_default.cfg, both are located in Steam\SteamApps\common\postal iii\p3\cfg. Open the files with a text editor and search for bind " " "toggleconsole" and replace it with bind "F11" "toggleconsole"



Now start the game and you should be able to open the console with F11.

Type cheats which do you want to use in the console:

To get the achievements with cheats like godemode, all weapons and so on just start a game and enter the cheats. Then set sv_cheats back to 0, save your game and restart your game. Now when you load your saved game you will still have all the weapons or enabled godemode. You can now get achievements easily in free roaming mode (finish story first) or just finish the whole game with it (lame...).

Go to your install folder Steam\SteamApps\common\postal iii\p3\SAVE and make a backup of slc.dat (copy it).
Open original slc.dat in notepad or a similar text editor and add this, above the other chapters:

"ROAM_HUB1" "0"

save and your done, start Postal 3. Select new game and Free Roam is there! Without having to complete the game!

Note:

It does not unlock all chapters, it just gives you Free-Roam leaving the option to you to complete the game.

This will unlock all chapters, this includes the good and evil path, as well as unlocking Free Roam!

Go to your install folder Steam\SteamApps\common\postal iii\p3\SAVE and make a backup of slc.dat (copy it).
