TL;DR Its a typical Kojima game, heavy on cutscenes, compelling story, and slow methodical gameplay that will enhance as you gain more tools and abilities.
The game takes Nier Automata's online connectivity to another level, allowing players to share equipment and items. Vehicles, safe houses, post boxes, and generators others construct/abandoned can be used by other players in their instance in certain areas of the world. Lost packages can be found and delivered as well. Post boxes act as communal points where players can leave items no longer needed for other players to use.
