New order.

Walkthrough of the "New Order" campaign (Hero difficulty): https://www.youtube.com/watch?v=WzP38DK8AWM

Thank you for the walkthrough. I watched the streams, and the tactics in the second mission are quite unique. Here's a small tip: you need to level up Orlando, as he is the one who continues the campaign. Also, you should give him the combined artifacts (they will transfer with him).
