Ark: Survival Evolved is an action-adventure survival game featuring dinosaurs and other prehistoric creatures that has been in early access on the PC, PlayStation 4, and the Xbox One for the past couple of years. Promising both single-player and multiplayer content, the title is slated for a full release on August 29, 2017.
However, it appears that Sony isn"t allowing PlayStation 4 owners to cross-play with Xbox One gamers.
Jeremy Stieglitz, co-founder of development studio behind ARK, and lead designer, programmer, and co-creative director of the title has stated that:
We have it working internally, but currently Sony won"t allow it :(
