Tbh this modpack was made for my friends.
You can use it if you want and it is on version 1.12.2
In this modpack you can craft weapon boxes to create guns and more firearms, you can create armor boxes for new and unique armor sets with different abilities, you can create viecles like tanks or planes to mess with your friends (in multiplayer) and you can build a rocket and go to space with the galacticraft mod.
Best used in multiplayer. You will have to change a few keybinds to get everything to work.
This modpack uses Flans mod and a lot of expansions and also some quality of life mods like tpa and /spawn. It also includes galacticraft (as stated earlier).
