ARK: Survival Evolved preview sells 1 million units on Xbox One, full release delayed until late 2016

Developer Studio Wildcard has announced that their dinosaur-themed action game ARK: Survival Evolved has sold 1 million units on the Xbox One in a preview release, along with 4 million on the PC.

ARK: Survival Evolved was first released in June 2015 on the PC, via Steam Early Access, and the Xbox One version was launched in December as part of Microsoft's Game Preview program. According to GameSpot, Studio Wildcard has decided to delay the full release of the game from a planned summer launch to the holiday time period of 2016.

In related news, ARK: Survival Evolved will launch its official Mods program in May. Community members will be able to submit mods could be integrated into the official game. The first such mod is a massive new map called The Center:

Designed by community member Ben Burkart, The Center adds an over-the-top, fantasy-themed map that doubles the size of the current game and is more varied than the original ARK map, with tons of new biomes, dungeons, floating islands, end-of-the-world waterfalls, massive ancient ruins, along with other wonders to explore and secrets to find. Drawn completely by hand without any auto-generated content, The Center is a massive increase in the game's official playable content and is free to both PC and Xbox One players.

Primitive+, a mod that's already available for the PC, will be launched this summer for all ARK: Survival Evolved members:

In the case of Primitive Plus, players are challenged to use only wood and stone without the benefit of advanced metals to create weapons such as guns. A whole new set of items and detailed new mechanics focus the player on 'primitive' survival, which fits snugly in the world of ARK. Primitive Plus will be playable as a functionality mod on all official ARK maps.
