Hello, there isn't a plan to make it work with mmo. I'm just one person so it's too big for me, but the good news is the plugin isn't obfuscated at the moment so you can hire an experienced developer to make both plugins work together.
No. When I designed Action Combat, it's only Action Combat. Multiplayer, especially online multiplayer wasn't included from the package. You'd need additional plugins for that and you'd need the help of MM0/multiplayer dev.
Yeah I found a multiplayer plugin so I will hope it does work with it. works with turned based built in and hoping it will for the most part work with action combat. Thanks for the answer
