Okay, I did find few old threads with similar question but i wanted to ask the current situation and since those didn’t have quite clear answer. 
So how would i update my Unity game if i find bugs, or change code, want to add stuff ect.
Without clients downloading full game again and losing saves ect.
Doesn’t Steam have solution for this as many Unity games on Steam update regulary…?
I know that there are patchers that you can buy in Asset Store, but i wanna know could this be with Steam (steamworks/steampipe)…
Also is there options now, or coming up for patching and adding steamworks in Unity Free?
