This expansion box includes the Arsenic and Emigration expansions, which add to Tinners' Trail with thematic new gameplay.

The Arsenic Expansion adds the extra resource of arsenic. Due to the danger of arsenic, it is processed at the cost of permanently losing work points, but with the reward of a big cash payout.

In the Emigration Expansion, you can send your workers overseas to gain ongoing benefits, such as income or free developments.
