If you want to play this pack, I'm still trying to make it work for the Technic Launcher but is available in Twitch.
Currently, Technic loads vanilla Minecraft instead of Superstes. I'm working on fixing this.
I just followed the guide for building a modpack with Technic and I'm 90% sure it works now.
I don't know for sure if the URL for the zip worked so sorry if it didn't.
Superstes was updated to version 1.2.0 3 years ago
