As the name says, I'd like to see 30mm Autocannons (honestly maybe 20-60mm Autocannons). These would be 1 in width and 2 in length. The Ammo factories would be the same size and produce clips for the Autocannons. They should be able to burn through a 30-rounds clip in about 5-6 seconds, after the salvo, the cannon should maybe have a cooldown and can store 3 in the cannon. The Storage would be 1x2 too and could store about 8-12 clips. Maybe you should be able to produce 45-rounds and 60-rounds clips too? Of course producing larger clips takes longer and they will take more place to store. For example: instead of 12 clips, the storage can only store 6 45-rounds clips and 3 60-round clips. The cannon can only store 2 45- and 1 60-round clip.
