Save values

You can directly change save values of your save.ini to change the progress that you have in the game. I would recommend that you play through the game once to unlock everything, the game is worth it, but if you somehow lose any item or character you earned this will show you how to get them back easily.

Monsters
All monster values are in order of appearance in your monster log, apart from the order in achievements and directly correspond to the monsters place in the log. Ex: mons1=1 in the save.ini in the second section makes the lemurian log appear, as it is the first entry.

Achievements
When you save the following commands in the [Achievement] section on its own line, it has certain effects on your game. To do this, make a new line stating "achievementX=2", where X is the number of a given achievement you want to unlock, preferably under other completed achievements (or their progress in case you unlocked none, if not even that, achievements are on the top of the file).

Character Unlocks:

7= Bandit

14= Enforcer

17= Han-D

20= Huntress

23= Engineer

32= Acrid

29= Sniper

There are 48 achievements in total that you can unlock with this method, however not all of them are documented as of yet because the order of appearance in the achievement list in-game does not correspond to numbers in the save file completely (some groups are numbered in order, i. e. 23,24,25 until 32 and then it goes to a very different number).
