Endless Space 2 - Vaulters adds the Vaulters faction to the turn-based 4X strategy game Endless Space 2. Players lead this resilient group of explorers across the galaxy in search of a permanent home after their long history on the harsh world of Auriga. The expansion emphasizes defensive strategies, scientific advancement, and military readiness while introducing new diplomatic options and minor factions.
Gameplay
The Vaulters focus on science and military strength. Their population traits provide bonuses to system defense, making them effective at protecting settled worlds rather than aggressive expansion. A key mechanic allows fleets to teleport across the galaxy, enabling rapid repositioning for defensive stands or surprise reinforcements.
Colonization works differently from standard approaches. The faction relies on a single master vessel, the Argosy, instead of multiple colony ships. Once established, systems benefit from strong defensive population bonuses and production focused on research. Heroes serve primarily as governors, delivering bonuses to system defense and scientific output rather than fleet command.
New ship designs draw from ancient Mezari aesthetics. These vessels feature numerous defensive modules and support capabilities that make them durable in prolonged engagements. An exotic module enables boarding actions that can result in capturing enemy ships. The Sisters of Mercy appear as a minor faction allied with the Vaulters, providing combat assistance in pursuit of justice against hostile forces.
Diplomacy with pirates receives expanded tools. Players can build relations through payments to gain favorable treatment, request targeted strikes on rivals, or use Vaulter-specific abilities to disguise ships as pirate vessels. Additional quests and deeds offer rewards that grant advantages in research, production, or military power when completed during exploration.
Game Modes
Endless Space 2 supports single-player sessions against AI opponents of varying difficulty. These matches allow full engagement with the Vaulters faction, including their unique colonization method, teleportation, and diplomatic features. Victory conditions revolve around scientific dominance, military conquest, or other empire-building objectives typical of 4X strategy titles.
Multiplayer options include competitive or cooperative matches where players can interact through the updated pirate diplomacy system. The expansion integrates seamlessly into existing campaigns, letting participants select the Vaulters for defensive playstyles or experiment with their boarding and teleport mechanics in head-to-head scenarios.
Faction Mechanics and Exploration
Vaulter gameplay rewards patience and preparation. Strong system defenses deter early aggression, while scientific focus accelerates technology unlocks that enhance both protection and fleet capabilities. The faction's history ties into broader Endless universe lore, with quests that uncover traces of their past and new homes.
Opbot DV8 returns as an unlockable hero with abilities aligned to defensive and research priorities. New deeds provide powerful empire-wide effects once unlocked, and four dedicated exploration quests introduce narrative elements and hidden rewards scattered across star systems.
Is It Worth Playing?
Endless Space 2 maintains an active player base with recent community updates that improved AI behavior, balance, and bug fixes as of 2025 and into 2026. Reviews remain very positive overall. The Vaulters expansion suits players who enjoy defensive 4X strategy, faction-specific mechanics, and diplomatic depth in a space setting.
Those seeking aggressive expansion or fast-paced combat may find the emphasis on system protection and research less appealing. Fans of the base game or similar turn-based strategy titles benefit from the added faction variety and ongoing support. The experience delivers consistent depth for sessions focused on long-term empire management and tactical fleet positioning.
