Anno2205-Savegame-Modifier

Python script to view and modify your Anno 2205 savegames, including difficulty settings!

Usage

First, clone this repository.

Then, locate your savefile and copy it to a save place:

• Windows (Ubisoft Connect): C:\Program Files (x86)\Ubisoft\Ubisoft Game Launcher\savegames\8a362a1f-2f5b-4d43-aa8c-4a918a88771b\1253\
• Lutris (Anno started through Ubisoft Connect): ~/Games/ubisoft-connect/drive_c/Program Files (x86)/Ubisoft/Ubisoft Game Launcher/savegames/8a362a1f-2f5b-4d43-aa8c-4a918a88771b/1253/
• Wine: ${WINEPREFIX}/drive_c/Program Files (x86)/Ubisoft/Ubisoft Game Launcher/savegames/8a362a1f-2f5b-4d43-aa8c-4a918a88771b/1253/

The last two parts of the path (8a362a1f-2f5b-4d43-aa8c-4a918a88771b/1253/) may be different on your computer.

You do not need the file 1.save. It only contains savefile metadata.

If you do not know which file is which savegame, use the dump command on them, which shows the name of your company.

Please keep in mind that modifying you savefile might break it. It is a good idea to create a backup NOW!

Command synopsis: python3 anno2205_save.py <savegame-file> <command> [<flags>]

Inspecting the savefile

python3 anno2205_save.py <savefile> dump       # human-readable output
python3 anno2205_save.py <savefile> dump --csv # CSV output (section,field,value)

Changing a difficulty settings in the savefile

python3 anno2205_save.py <savefile> set <field> <value>   # patch a difficulty field

# e.g. disable enemy invasions
python3 anno2205_save.py ./1774952996.save set DifficultyMilitaryInvasions 0

These settings can be modified:

DifficultyMilitaryEnemyStrength2			not tested
DifficultyStartCredits	Start Credits	Plenty (0), Medium (1), Sparse (2)	no effect when changed mid-game
DifficultyFacilityAuctions			not tested
DifficultyTraderPrices			not tested

The set command will create a backup of the file, named <orig-filename>.bak, first.

Please note, that not all properties have an effect when changed mid-game and will get overwritten! Most of the settings are also untested, and I don't know which value matches which in-game string. So if you are interested in helping me finding all values, let me know!

---

After creating the modified savefile, start Anno before copying the savefile back to the savefile folder! Otherwise, Cloud Sync will overwrite your changes. Wait for the start of the intro video and THEN copy your modified savefile over, overwriting the original.

Have fun tinkering and playing :)
