The Eastern Dunes is a region in Scorched Earth. It has a harsh environment, with many hostile creatures and a harsh climate. It does not provide valuable resources.
The Eastern Dunes are located near the Eastern Oasis, a relatively calm place for the rough Scorched Earth map. The Eastern Dunes are not as calm, however, with many hostile creatures present like the Rock Elemental, Sabretooth and Megatherium. Mantis roam, too. It has no vegetation, and the ground is pure sand, with some sand dune. While extremely rare, the Deathworm spawns nearby the Eastern Dunes.
It's not recommended you make a base here, even if water is in a [fairly] close proximity, because of its hostile and rough environment: The temperature is significantly warmer compared to its oasis counterpart: It's so hot here, that the heat can kill you in a few minutes.
