The Diplomacy system is a deeply integrated new gameplay feature, **built around three main components**: ##### Embassy Room - A Convenient Way to Interact A new embassy facility can be unlocked at your Player Headquarters (PHQ). Once unlocked, this room becomes the hub for your diplomatic endeavours. Here, Diplomats take their seats at a roundtable, offering quick access to faction representatives from across the galaxy. - Unlockable via research at the PHQ - Accessible through a new UI tab, alongside Research and Terraforming - Requires friendly relations to accept faction diplomats - New “Factions and Relations” menus to give a better overview ##### Agents - Specialists in Diplomacy and Espionage Agents are a **new class of hireable NPCs** who can be specialised in negotiation or espionage.

Changes in faction relations can have an extraordinary impact on the galaxy, as alliances, trade partners and supply chains shift. These events are based on real inter-faction relations (ally, neutral, hostile, etc.) and cover scenarios such as: - Trade disputes - Cyber attacks - Suspicions of espionage - Peace talks - Territorial claims As a player, you can: - Influence the event using an agent to steer the result in your favour - Enable Protocol Null to sow chaos and trigger periodic inter-faction events - Do nothing and observe the outcome Events can lead to shifting alliances, wars, ceasefires, or changes in strategic resource access, making th _[Truncated at 4000 characters — full notes: https://store.steampowered.com/news/app/392160/view/612045811444875943]_
