1. Go to savegame folder @user/username/appdata/roaming/void_war.

2. Open either Profile.sav or Autosave.sav with text editor.

3. Make edits and save file.

[Note]: I recommend closing the game while editing any files as some will be overwritten by the game and not apply if the game is open.

1. Go to savegame folder @user/username/appdata/roaming/void_war.

2. Open the Profile,sav file with a text editor.

3. Search for "currMetaCurrency" and edit to desired number (recommend just adding 0s).

4. Search for "lifetimeMetacurrency" and edit it to be higher than "currMetaCurrency" (I recommend just adding an extra 0).
Ex: "lifetimeMetacurrency":10000000.0, (7 zeros for lifetime),"currMetaCurrency":1000000.0 (6 zeros for curr)

5. Safe file and launch game to see changes.

1. Go to savegame folder @user/username/appdata/roaming/void_war.

2. Open the Profile,sav file with a text editor.

3. Search for "commanderUnlocks" and after commanderUnlocks you will see a string of commander names.
Ex: "commanderUnlocks":{"oCrewPlayerPriestess":0.0,"oCrewPlayerAssassin":0.0,"oCrewPlayerCyberfused":0.0,"oCrewPlayerDamned":0.0,"oCrewPlayerCybernetic":0.0,"oCrewPlayerOfficer":0.0,"oCrewPlayerMagus":0.0,"oCrewPlayerCannibal":0.0,"oCrewPlayerRoughneck":0.0,"oCrewPlayerExile":0.0,"oCrewPlayerMutant":0.0,"oCrewPlayerWight":0.0}
Set all the numbers after each commander name to 1 and they should unlock.

4. Safe file and launch game to see changes.
(method for unlocking ships did not work so I have removed it)

There is a new savegame editor made by The Mogician available for the following, please visit this link for more information: https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=3496880776

All previous information is sourced from Scourge and N4P4LM's guide posts and from here will be my additions.
Accessing autosafe file
1. Start a new game with whatever commander and ship of your choosing

2. Go back to the main menu and close the game (This creates/edits the autosave.sav file and the edits will not work if the game is running)

3. Go to savegame folder @user/username/appdata/roaming/void_war.

4. Open the autosave.sav file with a text editor.

Editing in-game currency
1. Search for "currScrap" and edit number to desired amount (recommend adding zeros Ex: 350000.0).

Editing in-game Missile Count
1. Search for "playerMissileCt" and edit number to desired amount.

Spawning items (Item numbers I've discovered at the bottom of the post)
Now there are three places to look at for spawning items; "cargoList": Place to spawn ship weapons and missile modules, "equipmentList": Place to spawn player weapons, armor, tools, and Psychic items, and "equipmentQt": This is the amount of an item you have corresponding to the slot it's in (this only needs to be edited when working with items that stack like tools).

Both categories; "cargoList", "equipmentList", and "equipmentQt", are setup to reflect the in-game positions of items.
For example the cargo list is setup as "cargoList":[-1.0,-1.0,-1.0,-1.0] reflecting the four slots of ship weapon and missile module slots (they are in order from left to right) and "equipmentList":[-1.0,-1.0,-1.0,-1.0,-1.0,-1.0,-1.0,-1.0] reflecting the eight slots for armor, tools, player weapons and psychic items.

Spawning ship weapons and missile modules
1. Search for "cargoList" in the autosave.sav file

2. Replace the -1.0s in [-1.0,-1.0,-1.0,-1.0] with the desired item number.

Spawning player weapons,armor and psychic items
1. Search for "equipmentList" in the autosave.sav file

2. Replace the -1.0s in [-1.0,-1.0,-1.0,-1.0,-1.0,-1.0,-1.0,-1.0] with the desired item number.

Spawning tools
1. Search for "equipmentList" in the autosave.sav file

2. Repace the -1.0s in [-1.0,-1.0,-1.0,-1.0,-1.0,-1.0,-1.0,-1.0] with the desired item number.

3. search for "equipmentQt" and replace the 0.0s in [0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0] to the desired amount of the item you want.
Ex: to spawn a med drone and cryofoam
"equipmentList":[3718,-1.0,-1.0,-1.0,4692,-1.0,-1.0,-1.0]
"equipmentQt":[2.0,0.0,0.0,0.0,90.0,0.0,0.0,0.0]
This would spawn 2 med drones in the first slot and 90 cryofoam in the 5th slot (yes, you can go over the cap of 2 but to use more than 2 you need to assign the item to a unit then right click the item while it's in the units inventory and it will take out 1 item at a time from their inventory so that you don't have to save and close the game a bunch of times to get all your units to have their tools).

Spawning Modules
1. Search for "moduleSlot" in autosave.sav
"moduleSlot" will be embedded in a string like: {"allied":1.0,"x":0.0,"y":0.0,"savedObjID":133193,"image_angle":0.0,"persistent":1.0,"image_blend":16777215.0,"moduleSlot":2.0,"obj":"oModule_restHealBonus"}
I don't know how much of it is important and therefore I ended up saving the entire string once I had the module I wanted already found and installed naturally on my ship and then pasting the entire thing over a preexisting string.
The only truly important parts of the string to my knowledge is "moduleSlot":X.0 and "obj":"XXXXXXXXXX" but I assume things like objID and such are just as valuable hence the pasting over the entire string.
Each "moduleSlot" will have a number(0.0,1.0, and 2.0) corresponding to the three module slots on a ship. Pay attention to this and make sure you don't paste a Module 2.0 string on a module 1.0 string resulting in two module 2.0s (haven't done this but I assume it might mess things up), If you do end up doing so just make sure to check and change it so you have a 0.0, 1.0 and 2.0.

Be sure to save the file after editing anything and ensure the game is closed. After editing relaunch the game to see results.
