The example weapon mod was good to see how to mod weapons, and there are PDFs with some basic documentation. Lots of nostalgia with the unreal editor, as i havent touched ue3 since i got the ue4 beta. I started tinkering with the mod sdk to try to create a lightsaber, just to see the workflow. First of all, i took a look at the basic documentaion, and found it does have the full unreal engine editor, modified for xcom2, with ALL the gameplay scripts in unrealscript. Downloaded almost 50 gigabits with 66 gigs of HDD space. Yesterday, after a quite huge marathon playing xcom2, wich its quite a nice game, i decided to take a look at the mod SDK. An article on how i did it and all the source code, with assets, for the mod its here Light Sword Xcom2 mod tutorial.
