► BUILD YOUR SHIP. JOIN THE WAR. The galaxy belongs to those strong enough to claim it. Build a powerful spaceship, challenge other commanders in PvP, join an alliance, and fight alongside your allies in massive Alliance Wars. Every upgrade, every module, and every decision brings you closer to becoming a force the galaxy can't ignore. Will you build the ship everyone fears? ► CREATE A SHIP THAT'S TRULY YOURS Start with a basic vessel and turn it into a machine built for battle. Collect weapons, shields, engines, armor, and special modules, then combine them to create your own setup. There is no single perfect ship — only the one that works for you. ► WATCH YOUR BUILD COME TO LIFE Once your ship is ready, send it into battle and watch your strategy play out. Weapons open fire. Shields absorb incoming attacks. Special abilities turn the tide. A setup that looked perfect in the hangar may need to change after meeting its next opponent. Upgrade, rebuild, and try again until your ship can handle whatever the galaxy throws at it. ► CHALLENGE OTHER COMMANDERS Your toughest opponents aren't waiting at the end of a mission. They're building their ships right now. Take your strongest setup into PvP and see how it performs against other players. Improve your build, climb the ranks, and come back stronger after every battle. But you don't have to conquer space alone. Join an alliance, grow together with other commanders, and enter Alliance Wars where every member can make a difference. Fight for victory, valuable rewards, and your alliance's place among the strongest in the galaxy. ► EXPLORE THE UNKNOWN Beyond the safety of your hangar lies a galaxy filled with dangerous sectors, hostile fleets, mysterious encounters, and valuable resources. Travel from sector to sector, complete missions, defeat increasingly powerful enemies, and discover what waits deeper in space. The farther you go, the greater the challenge — and the stronger your ship will need to become. Every new destination is another test for the vessel you've built. ► KEEP GROWING WHILE YOU'RE AWAY Your journey doesn't stop when you leave the game. Come back to new resources and fresh opportunities to improve your ship. Spend your rewards on upgrades, unlock new possibilities, and prepare for the next mission. Jump in for a few minutes or stay to perfect your build — there's always another upgrade, battle, or sector waiting for you. ► YOUR SHIP. YOUR ALLIANCE. YOUR GALAXY. The hangar is ready. The next sector is waiting. It's time to take your place among the stars. Privacy Policy: https://say.games/privacy-policy Terms of Use: https://say.games/terms-of-use
