Bullets

Let's look how the production of ammo can be a link of 3 industries.

→ Example 1

In the game there are bullets with cartridge cases produced by heavy industry. However, this production requires metal bars created in light industry.

→ Example 2

Shotgun ammo requires copper and lead, or other alloys. Copper comes from light industry, while lead comes from heavy industry.

→ Example 3

The game will also feature energy ammo which doesn't require cartridge cases. To produce high-quality energy ammo, however, you will need heavy industry related items.

To see how industries are interconnected, see the picture above. It might be a bit difficult to understand at first sight, but the in-game implementation will be super simple and clear!
