At the core of the 8.00 update for X4: Foundations is the new Diplomacy system, which will make the sandbox and economy simulation elements of X4: Foundations shine in new ways. The Diplomacy system is a deeply integrated new gameplay feature, built around three main components: A new embassy facility, a new class of hireable NPCs (Agents) who can be specialized in negotiation or espionage, and the ability to trigger and influence dynamic diplomatic standing between NPC factions.
