About this Modpack
This is a Lunar Client alternative modpack, that has almost all the features in Lunar, and even more, allowing you to customize all the individual mods, and even add your own mods!
Why use Comet Client instead of Lunar?
Comet client offers almost all of the same mods, including Essential so a friend system and hosted worlds can be used too! On top of that, you can add ANY mod you want to comet client, meaning there's infinite customizability!
How can I customize the mods in here?
To customize the mods, you can either check with Mod Menu on the home screen or escape screen, or for some mods, it will have a custom keybind which you can find and edit in the controls section.
How can I use the friends system now? How can I host worlds?
Don't worry, Essential has all the same features including a friends+DM system, FREE hosted worlds and more! Your change to Comet Client will be so seamless that you wouldn't notice a difference when playing!
When will it be updated to [insert version]?
When all of the mods this modpack depends on are updated, Comet Client will update as well. We'd love to release as soon as possible, but that's really dependent on the creators of the mods we depend on!
