Supply Lines

Unlocked by scrapping Sir Pent. You beat a train; you keep the rails. Every cleared 10-wave segment becomes a depot on the logistics map, and Scrap lays track between adjacent depots.

• +1 percent Scrap per linked depot, +2 percent per completed loop, hard-capped at +25 percent. A management toy with a low ceiling, on purpose.
• Derailments: now and then a track goes down. One click re-rails it instantly; left alone, the crews fix it in about ten minutes. Idle players lose pennies, not progress.
• Track gets pricier the deeper the depot, anchored to that segment's Scrap income, so the network grows with your frontier.
