Ark Survival Evolved started off as a game preview that was released December 16, 2015 for Xbox One, fully announced December 6, 2016, and eventually released on August 29, 2017. This game was developed by the studios Wildcard, Instinct Games, Efecto Studios, and Virtual Basement.
Although the game was released in August of 2017, the first DLC was released September 1, 2016 called Scorched Earth. The DLC itself is an open world that’s a desert with new creatures, new weapons, and new landscapes, plus the ability to take over/build new bases and tame new creatures. There are also new dangers like heat stroke, and with that, water is scarce, where you can find it anyways.
Ark Survival Evolved had released a second DLC called Aberration which is based around Ark that was damaged, has a toxic surface, and most of it is played underground. The radiation has caused the creatures on the surface to have mutated, giving them new abilities like being able to glow. There is also an abundance of new tools to help you explore this radiation filled Ark such as the Wingsuit and other hazmat suits.
