ARK Survival Evolved
Enjoy the new Single Player Settings mode in ARK, which speeds up earning XP, crafting, taming dinos and more. The overall difficulty of the game is also altered for solo players, and with these new settings, setting out for a single-player adventure in the world of ARK is a smoother and more enjoyable experience for players who prefer to go it alone!
