jokei: It's too damn difficult. Any working cheats that aren't shady "trainers"?
Here's the closest thing to a cheat I'm aware of.
Please use this only if you're THAT desperate! Still here?
Have you made it to Wolfman's camp in the Silent Forest? You'll notice that there are two crates next to the Wolfman, both of them locked. There's no "proper" way to open these crates - at least none that I'm aware of.
However, you can find the access code by rummaging through the save file. You'll find them here:
Windows: %USERPROFILE%\AppData\LocalLow\Acid Wizard Studio\DARKWOOD
macOS (OS X): ~/Library/Application Support/Acid Wizard Studio/DARKWOOD
Linux: $HOME/.config/unity3d/Acid Wizard Studio/DARKWOOD
Open folder for the profile you use in your current playthrough. Then open the file sav.dat with a text editor. Search for the line "crate1_med_wolfman_camp_01" and "crate2_med_wolfman_camp_01", you'll find the access code right next to it. You can now use these codes to unlock the crates in Wolfman's camp. You'll find an Uzi in one of the crates, which is (as far as I'm aware) not available anywhere else in the game and is the closest thing you'll come to playing Darkwood in godmode. The thing obliterates enemies while eating up the fairly easily obtainable pistol ammunition.
