You say Fire Everything, but it's not even close! For starters, the entire Production category, most particularly modules. Also a bunch of Logistics, Science, and Equipment/Combat categories.

The title is a bit more of a Star Trek joke than anything, but this was a work in progress, with the eventual goal of adding almost everything.
I do hope to eventually come back to it, unfortunately Space Exploration has the recipes for the cannon very restricted, and I have to use a workaround to add certain types of things. A lot of it requires unique recipes for each item to pack. If you have anything specific you wish to have added, I can see what I can do until I get the time, motivation, and desire to play/test factorio again.
I did just add Meteor Defence Ammo and Meteor Point Defence Ammo by request from another thread.

But thank you for the feedback, and thanks for trying the mod! :)

Love the mod! lol legit came here to look into the same thing. Just unlocked them on my game, and it definitely doesn't fire everything. But still love the mod! Great work!
