Save Kickers 2: A Guide to Save Editing

You need a plaintext editor for savegame edit, I personally recommend Notepad++, but you can go for others including UltraEdit. MS Notepad works too but I wouldn't recommend using it.

Where is the savegame?
For Windows:
C:\Users\<username>\AppData\Local\KillHouseGames\DoorKickers2

Innate ability:
Each trooper has a set of innate abilities, search for the name of the trooper and down under you can find them, change them to whatever you desire.

You can copy and paste this onto the original section as well:

<InnateAbilities>
<InnateAbility name="Marksmanship" percent="100"/>
<InnateAbility name="AssaultShooting" percent="100"/>
<InnateAbility name="FieldSkills" percent="100"/>
</InnateAbilities>

Battle Honor Upgrades
Troopers can get battle honor upgrades, they should go between the statistics section.
Normally you can only get 2, one of each for a single trooper, but with save edit, you can get all of them.

<Upgrade name="BH_Offence1"/>
<Upgrade name="BH_Offence2"/>
<Upgrade name="BH_Defence1"/>
<Upgrade name="BH_Defence2"/>

Battle Honor
In the line with the squad name, you can find the battle honors amount, alternatively, search for "battleHonors=" (without quotation marks). Change to desired number.

Doctrines
For doctrines, they should be between <Doctrine> and </Doctrine>. Feel free to copy and paste all the doctrines over to the right location if you want to unlock all the doctrines.
