ARK: Survival Evolved just received an update across all platforms, adding new Genesis Chronicles event content that will lead to the release of the Genesis expansion. On PS4, the update will set you back 13 GB. The update will add Explorer Notes, armor, and more, and is available to download right now. The Explorer Notes are a window into the future expansion, tying it and the wider ARK narrative together.
