Replace your files with the 100% files
Go to C:\Users\YourName\AppData\Roaming\Godot\app_userdata\Chillquarium\V7
Go to this Google link HERE
Replace tank_0_objects, tank_1_objects, tank_3_objects, tank_4_objects, tank_5_objects
If you replace the whole file you will be missing the steam_autocloud, which I believe is necessary so don’t do that.
You may also replace tank_2_objects, but there’s no fish there (there are 5 fish packs and 6 tanks). You may also replace globals, but it’s not necessary, it contains money and mercy values.
Launch the game and go through all tanks
I got these files by coding a macro in python to replace all instances of fish with adult fish and then swap the rarities around, but I think you all would agree that downloading these files instead is way way easier.
