There are many mods that add weapons.
But it would be great for an official keen vision to add more weapon times/balance protection and new weapons to make combat more fun then just weapon spam doom walls or ramming or gravity stuff.
Things like proper naval weapons. Heavy cannons, Auto cannons Flak, Missiles tracking and not and heavy duty torpedo's. maybe even add some customization to them via blocks just how we have all the add ons for refineries and such!
Game-play can be heavy extended with the *conflict* side of things. HOW to have conflict needs to be updated basically!
