Scorched Earth was released on September 1, 2016 for the PC version of ARK and for Xbox One at the initial price of $19.99 USD. It was released on PS4 on December 6 for the same price.
As for the main game the theme music for Scorched Earth was composed by Gareth Coker. You can hear it on his Soundcloud account. [1]
Scorched Earth adds 11 new creatures, over 50 new items, a new boss, and a whole new map.
Creatures tamed and items recieved can be brought to the vanilla island and used by people with and without the expansion. Items from the DLC can also be spawned manually if you don't own the expansion pack. Two of the new creatures have multiple variations, namely the Jugbug (Water and Oil) and the Wyvern (Fire, Lightning, and Poison).
The Desert Map
Being entirely desert rather than an island surrounded by water, heat and water collection become more challenging obstacles. Natural water sources are rare, requiring the collection of water from other sources, such as cactus, water wells, Jugbugs, or Morellatops. Heat stroke is a potential side effect of too much heat exposure, having a similar effect to being drunk. Also the naturally harsh environment damages generators and certain structures.
Scorched Earth has three unique weather patterns: Sandstorms radically reduce visibility and drain stamina, Superheat will drain your water at a much faster rate than normal heat and induce Heat Stroke fairly quickly, while electrical storms will temporarily shut down electrical devices and prevent firearms from firing.
Superheat can be quickly stopped if you go very close to the Oasis. Desert Goggles can be used to see better during sandstorms.
Scorched Earth adds 3 new artifacts, which are needed as part of the tribute to summon the Manticore.

Trivia
Unlike the main game, where almost all creatures are based on extinct animals, this expansion pack added creatures inspired by non-extinct animals (e.g. Jerboa, Vulture, Thorny Dragon) and creatures from mythology (Deathworm, Rock Elemental, and Wyvern).
