Chariot

This achievement will unlock as you complete the story. You will need each required chariot upgrade to get to the sepulcher of the given chapter (not level). There are a total of 5 chariot upgrades. In order to unlock a chariot upgrade, you will need 2 chariot scrolls. A chariot scroll is different than a gadget scroll, for the fact that you must deliver a chariot blueprint crate to its destination to acquire a chariot scroll. In other words, do not miss a delivery of a blueprint crate.

Note that if you do miss a delivery and do not remember which map it was, you can click on each map and the ones that have chariot scrolls have a legend reading 0/2 scrolls, instead of 0/1. There should be two maps in each chapter that have 0/2 in their legend, as you will need 2 chariot scrolls to achieve the chariot upgrade required.
