Two (3 more to come!) Factions Unlocked

The Phalenoid Advance

Embark on a celestial journey with The Phalenoid Advance, a moth-like faction that reveres culture, science, and peace. This diplomatic faction prioritizes peaceful solutions over conflict, using their far-reaching Influence to foster annexations if left unchecked. With their unique Nocturnal Ability, they alternate between "Waking" and "Dreaming" states. "Waking" bolsters Growth and Manufacturing, while "Dreaming" supercharges Research and Influence. Their Hopeful trait elevates planetary Approval for harmonious expansion.


The Luxar Dominion

Welcome the Luxar Dominion, a faction steeped in arrogance and paranoia, yet gifted with cosmic telepathic abilities. With their telepathy, they wield the Pandemonium and Serenity Executive orders. "Pandemonium" spreads turmoil via chosen negative modifiers, while "Serenity" imparts chosen positive modifiers, all driven by their telepathic prowess. The Luxar Dominion's Paranoid trait enhances ships within their borders, granting a formidable increase in Hit Points and Attack power. 


Updated Ship Designer

Crafting your vessels is now more intuitive than ever, as we've streamlined the process of placing equipment on ships, ensuring a seamless and efficient design experience. Dive deeper into ship intricacies with enhanced information, allowing you to gain a comprehensive understanding of your creations as you build them. 


Revamped Diplomacy Screen

The Diplomacy Screen now brings clarity and strategy to the forefront. This significant update emphasizes resources, relationships, and more, allowing for better-informed decisions on trade and alliances. At the center, a streamlined table vividly communicates each player's resources. Meanwhile, the left-hand screen concisely presents a civilization's strengths, abilities, and diplomats, simplifying relationship management. This revamped Diplomacy Screen equips players with the insights needed to navigate diplomatic intricacies and make impactful strategic choices.


"Name a Star Contest" Winner Names Added

The "Name a Star" contest winners have now become part of the game, with their submitted star names making their way into the cosmic expanse. As you traverse the galaxy, you'll encounter these named stars! This seamless integration of player contributions adds a layer of personal connection and authenticity to the Supernova experience.


Your continued support and feedback have been instrumental in making this game even better. As we continue to refine and enhance the game during the Early Access phase, we look forward to your valuable insights and suggestions.
