Contracts and factions The contract system is the game’s spine. Multiple factions—each with their own agendas—offer missions that influence the island’s balance of power. Choosing to aid one faction will anger another, and this dynamic reshapes NPC behaviors, access to resources, and mission availability. That interplay creates emergent stories: the same mission can play out very differently depending on prior choices, and betrayals feel impactful because they alter the world rather than just your score.
