I saw this from another AC forum, and this is what one of their members posted:
1. Get a bracelet from Bali
2. Go to the Country House of Mr. Wulf
3. Get a Certificate of Authrnticity from a neighbors Research Lab
4. Buy an Atlas from the Bookstore
5. Visit the Resaerch Lab to understand the decription.
6. Find some Map Draftes in Book Stores of your Neighbours. (6 pieces)
7. Fly to Machu Pichu using the map from warehouse(Turboprop, 1 Flight)
8. Recover the Bas Relief in the Machu Pichu(Turboprop, 1 Flight)
9. Buy the Map to Tolan at the Airship Store
I'm soon to start step 7, haven't used a map yet to fly to Machu Pichu (earned 2 maps after completing step 6). Need to fly turboprops enough times to get 6 of the Bas Relief items if I want to go for the pyramid earned by completing the whole collection 6 times.
Have to wait for the airship to dock for the other maps...anyone know when it is coming next?
Just sharing what I found on another forum, hope it is useful.
