Unreal Engine 4 is already open, this game does not have any encryption or compression at all. There are mod loaders for it already, so anyone can make multiplayer mod for it, the problem is that 1. The game is currently in early alpha stage and didn't even release yet and 2. Making a multiplayer mod will be very hard and will take a lot of time
Isn't .pak file in VotV\Content\Paks already contains all scripts?
Also, this game has a page on thunderstore with mod loader and some other mods: https://thunderstore.io/c/voices-of-the-void/, I didn't test any of them yet but I think you can use UE Blueprints for modding the game
I making games on UE4, and I know how to make local (friend to friend game, with out servers), but big problem is PLUGINS (FckThem) some of them cost money, soo~
If mrdrnouse (the author) send plugins, I will make multiplayer!!!
