ReCore: Definitive Edition comes out tomorrow, and now we're getting an advance look at everything new that's coming with it. The action game was first released last year for Xbox One and PC, and now the Definitive Edition features enhanced visuals and a whole of host of extra features, including a new Corebot Companion and a new chapter in the story.

Eye of Obsidian is the name of the new adventure. In it, players join the "plucky" Corebot Violet and head into the permanent midnight of the Starving Sea, which is a previously unexplored region of Far Eden. You can expect ancient enemies to be waiting for you, as they "plot their revenge on the last remnants of humankind."
