There is no f**cking way to make a mod that can ACTUALLY add
multiplayer because of VotV code (or Blueprints)
that made only for ONE player, not more. Besides, the game does not
have any Replication,
so you wont see any movement from any players in your session.
> Longer answer
Game fully incompatible for multiplayer.
You can just add Create Session and Join Session nodes to your mod, but it wont work correctly
(especially Join Session node).
And that's mostly not your
mod problem - it's Gamemode/GameInstance/Player
Blueprints problems, because they made only for one player.
So, the only method how we can add
Multiplayer for VotV is just to modify original game blueprints.
> [UPDATE] Have someone even tried to do mod for this?
Idk if someone even tried to do this besides me... If you tried - DM on discord me with your story of
attempts to do multiplayer mod. Right now we know only one guy who started making Multiplayer mod for VotV - kokosko. Please, don't hurry him and ping for ETA.
Here are his progess from start:

> What do you mean Network nodes wont work correctly?
Well... You CAN actually Create session, but for some reason game will not join to it with just
default Join Session node.
What reason? I don't know for sure, especially when logging is disabled. (This is because VotV builds
are in Shipping mode).
But you can Join session using this node: (I used LAN for testing)
Results of joining:

> So, there is no way we can make multiplayer mod?
For this moment I don't have any idea how to make this. The only way to make multiplayer support is to
get access to Source Code of VotV and modify it's blueprints.
> There is no way to get source code? Or decompile game for it?
I think somehow we can get them... But bruh, that will take much time
