Creating new races and perks?
 

Just wanted to ask if it's possible, kinda want to add an elemental race, I'm really good at photoshop and I could really make it realistic but I'm really bad at finding this kind of little information, would be very thankful as always.

Races can be added through the .txt files in Sessions/[campaign_name]/ses.kfs. Just ctrl-f with notepad for the term "race" in the files until you find the lines for the races. About localization, it should be in one of the units' localization files (use the other races' info as template). Special perks can be added in subturns.lua.

where do i find subturns.lua?

In the same place as all other campaign-specific files.
