There are heroes and zones that aren't accessible in the current game version (Ver. 1.3). And in this guide, you will learn how to modify a data file to include those heroes and zones in your campaign.

Warning:
This guide involves editting the following file:
\LostTechnology\script\official\scenario.dat
Be sure to make a backup file, and place the backup outside the game folder.

The data file that you need to edit is called Scenario.dat, and it's located in the following directory path:

C:\Program Files (x86)\Steam\steamapps\common\Lost Technology\LostTechnology\script\official\


Right click "Scenario.dat" and choose "open with".

The file isn't encrypted, so you can open and read it with a standard text reader, like: Notepad, TexEdit, etc.

Once you open the file, the content should similar to this:

There are five hidden heroes that you could unlock:
eratosthenes
tycho
innes
lovelace
keldysh

And to do so, you need to scroll down the data file until you see the "roam" section:



1. Add a comma sign " , " after "lenuta".
2. Press the "enter" key to add another line.
3. Type "eratosthenes,tycho,innes,lovelace,keldysh"



Congratulations, you just unlocked those hidden heroes. Here's a sneak peak of one of them.

There are six hidden zones that you could unlock:
z0s3
z0s9
z0s10
z3s6
z4s4
z6s4

And to do so, you need to scroll down the data file until you see the "showSpot" section:




1. Add "showSpot(z0s3)" between "showSpot(z0s2)" and "showSpot(z0s4)"
2. Remove "//" behind "showSpot(z0s9)"
3. Remove "//" behind "showSpot(z0s10)"



4. add "showSpot(z3s6) after "showSpot(z3s5)"
5. add "showSpot(z4s4) after "showSpot(z4s3)"
6. add "showSpot(z6s4) after "showSpot(z6s3)"



Congratulations, you just unlocked more zones to play with.

Just in case, here's a side by side preview of the data file before and after the edit.



And here's a sneak peak of one of the hidden zones.

Hi, guys.
mischa.zehnbauer found more hidden heroes to unlock.

dimitrie,isidore,ileana,marius,ion

And there are still some more:

ludolf,hartwig,karsten,hihiro,masterchimera,mastermail,masterdragon

There's an extra hidden zone, but this one requires an extra step to implement.
The hidden zone is:

z13s8

First, you need to add them into the spot list, by simply adding them on

z13s1, z13s2, z13s3, z13s4, z13s5, z13s6, z13s7,

to

z13s1, z13s2, z13s3, z13s4, z13s5, z13s6, z13s7, z13s8,

and then add them in the showSpot list on

showSpot(z13s1)
showSpot(z13s2)
showSpot(z13s3)
showSpot(z13s4)
showSpot(z13s5)
showSpot(z13s6)
showSpot(z13s7)

to

showSpot(z13s1)
showSpot(z13s2)
showSpot(z13s3)
showSpot(z13s4)
showSpot(z13s5)
showSpot(z13s6)
showSpot(z13s7)
showSpot(z13s8)

Enjoy. If there's any difficulty in the guide, feel free to let me know.

I have tested the campaign myself, and there hasn't been any problem, but if you encounter any, feel free to let me know.
Happy conquering~
