Nav Coordinates are Pickups appearing as spheres with a dark "space" effect inside. They are commonly found inside storage containers and lockers on every level, including the Orokin Void, and are rarely dropped by Eximus, Feral Kubrows, and Drahks.
In advance of the official Heart of Deimos update, Orokin Derelict Nodes have found a new home orbiting Mars and no longer require Keys to play! All Keys in your Inventory or in-progress in the Foundry have had their Credit and Resource costs refunded, while Nav Coordinates can be sold for extra Credits (see below)!
Nav Coordinates can now be sold for 25 Credits and Lephantis Nav Coordinates for 500 Credits.
Next Hotfix will make Nav Coordinates sellable for 25 Credits. As for the Lephantis Nav Coordinates, they were automatically melted for 500 Credits each when you logged in - no need to manually Sell!
