Dont know yet. Wont know until after the game is finished.

You could of easily used the search function for your answer too.

Would assume not since there isnt a need for official mod support. That's only really needed when you're attempting some level of anti cheating

For what? There's no blueprints and no official mod support. There's nothing to share.

but mods makes the game way better thoe so i though it would of already been in work or implemented somehow apart from Nexus ;[

K and?
Nothing is stopping mods from being made, nor used.
Yes updates break some, but even with workshop supported mods would get broken with updates.

At this point in development it would be nothing but a waste of resources for the dev team to work on bringing it to steam workshop.

I can also do without all the low quality troll mods and virus that get uploaded to the workshop.
