Quick question, how modable is the game?
I've a little idea for a game mode I think would be fun but ive very little experience with modding, would it require very advanced knowledge to change a few things in the game files?
Currently only mapping is supported, but Relic have mentioned that they're looking at other areas (and the categories in the Steam Workshop support this).
Depending on how familiar you are with (simple) code, making small changes is generally a low-effort job that doesn't require much expertise. You can open up the game archives and read the file contents with the below files, to get an idea of where you stand:
I'll have to have a look later, this is probably a little more ambitious than just tweaking values!
I'll explain more later when I'm in front of a computer
