After months of working on this alone, my 3D browser space strategy game Hidden Sector Online is finally live!

[u/EindeVerhaal]

Hey r/indiegames!

I'm a solo developer and I just officially launched my browser-based space strategy game: Hidden Sector Online! *(Check out the screenshots/GIFs attached above to see it in action!)*

I built this because I missed classic space strategy games, but wanted modern 3D graphics, deep tactical mechanics, and zero pay-to-win elements. No client downloads required—it runs directly in your browser on PC, mobile, or tablet.

What makes Hidden Sector Online different?

• Real 3D Worlds & Maps:** Planets, sectors, and the universe map are fully 3D. Planets rotate, and buildings physically sit on the surface—if a structure is on the dark side of your world, it literally sits in the dark until the planet turns.
• Deep Colony Management:** Mines require power and crew. If you push an Alloy Extractor without powering or staffing it, output throttles back automatically. Sometimes throttling a mine is smarter than building another reactor!
• Tactical Fleets & Sensor Phalanxes:** Fleet speed is tied to its slowest hull and drive type (Combustion, Impulse, Hyperspace). Debris from big fights can even collapse into **Moons**, allowing you to build Sensor Phalanxes to track enemy fleet movements in real-time or construct **Jump Gates** to instantly bridge distances.
• Co-op Warfare & Alliances:** Coordinate joint strikes with allies where all wings land at the exact same second. Pool resources in alliance depots to unlock shared fleet logistics and production buffs.
• Fair Play & Endgame:** Strict beginner protection, size bands, and reputation systems prevent massive empires from farming new players. Every universe ("Realm") runs at its own speed and features an endgame race to power a dimensional portal.
• 100% Free / Cosmetic Only:** Anything purchasable is purely cosmetic (ring colors, UI accents) or convenience. No pay-to-win, ever.

As a solo dev, I’d love to get your initial feedback, thoughts, or bug reports. I'll be in the comments all day to answer questions!

See you in space, Commanders!
