Many of you may know you can't use Cheat Engine to manipulate this game, so I'll show to to make this game easier for you.

First thing first you need start a New Game (or if you already played a game, just skip this) because of course you will need a new Savegame Data. Choose your perks if you have any and Start the game.

After short intro of game, you will find yourself in a hotel, with some health and hunger stats. You can change it by edit the Savegame Data. So, what you'll need now just exit the game.
Yep, no joke. Just exit the game and let's find and edit the Savegame Data file.


Note: just make sure you closed the Skyhill application, because I already have tried edit the Savegame Data but not close the game. I won't works. :|

Every you move, what and how many your items in inventory, or your health and energy (and even enemy health base) is saved in this Savegame Data file.

You can find in this address:
C:\Users\%yourUserName%\AppData\Local\Daedalic Entertainment GmbH\Skyhill\Savegames

Please remember, each of you may have different and specific user name. You can find your username when you logged in or simply open Windows Explorer, search for C:/Users/ folder.

Sometimes you may also can't find the "AppData" folder, because it's hidden from by default. but you can still type it manually in address bar.

After you find the Skyhill Savegame Data's folder, you can edit the "Db.xml" by right-click and choose edit with notepad.


And voila! Now you can start edit your savegame data!

You can try experimenting by edit the number in red rectangle i shown to you above or even edit your inventory items by find "<character_inventory>" in these Savegame Data.
For now we will focus how to get all achievements in Skyhill.

Now scroll down to the bottom of Savegame Data, and you will find "<achievements>".

Just change is_unlocked="False" become is_unlocked="True"


Save file and now open and continue you gameplay.
Expect something happens on your right bottom screen, the super ez achievement in your life.

Well done for your completion achievements in Skyhill game, now go find another game.
