Please NO Data-Mining.
The thrill of discovery is what motivates us ( as well as the cash it puts in our pockets ) .
Post your discoveries here and help piece together the ancient past.
To begin this Dig-Dug lifestyle, place out a SIGNAL BOOSTER, insert 1 NAVIGATION DATA and search for Ancient Relics. When you arrive at the coordinates, ask the Ancients for Knowledge of the Past. Once you arrive at your destination, search for chests containing keys. After you have 3 keys, search for a large chest.
Most ruins have a similar layout. Becoming familiar with it will help expedite your search.
At this time there is no known purpose for your discoveries except to sell them for profit. If anyone has other knowledge, please advise.
I would like to thank @MacForADay for inspiring me to dig.
A little more info from @TravelEcho :
1. Only one person in the team can retrieve the each key and contents of the main chest.
I notice there are usually 5-6 keys, so whoever is to open the chest should pick up at least three of them.
2. There are currently NO weather effects, on the grounds of a dig.
Here is a typical dig site.
