The casings are produced by the heavy industry sector. However, creating these casings requires ingots, which are smelted in light industry. ### Example 2 To produce shotgun shells, you'll need copper and lead (or other metal combinations). Copper comes from light industry, while lead is produced by heavy industry. ### Example 3 The game will include energy-based ammunition that doesn't require casings. However, producing high-quality energy ammo will still need components from the heavy industry sector As you can see, the industries are interconnected - check the diagram below. Yes, the system might appear complex, but its in-game implementation will be maximally straightforward and intuitive!
