About this game

An alien fleet pierces the atmosphere, its warships blotting out the sun. Cities crumble, defenses fall, and the planet teeters on the brink of annihilation.

You are humanity’s last line of defense. One pilot. One ship. One chance to turn the tide.

Orbital Siege fuses the classic arcade shooters with planetary defense, delivering relentless action.

🔥 Intense Shoot-'em-up Action: Survive escalating enemy waves and take down bosses.

⚙️ Upgrade & Defend: Boost firepower, speed, and shields with power-ups. Block enemy fire with defensive orbs, hunt foes with devastating lasers and homing missiles, and activate planetary turrets.

🎯 Dodge & Weave: Slip through storms of enemy fire with sharp precision.

🎨 Pixel Retro Style: Vibrant pixel art that celebrates the golden age of arcade gaming.

    Development Update

    Greetings, Commanders!I'm hard at work on the upcoming June update for Orbital Siege, and it’s shaping up to be another ambitious patch. I wanted to give you a sneak peek at the new mechanics currently in testing that will fundamentally change how you approach each run.New Mechanic: The STARHOP SystemPrepare to hunt for power. In the June update, you’ll be able to collect power-up letters to spell out S-T-A-R-H-O-P. Depending on your precision, you can unlock two distinct power tiers:Overdrive (Collect in Any Order): Complete the word in any sequence to trigger Overdrive, granting a permanent +10% boost to all ship stats for the rest of your mission.The Wingman (Collect in Sequential Order): For those who want a true partner in the void - collect the letters in the exact order (S-T-A-R-H-O-P) to summon a Wingman.Tactical Escort: The Wingman joins the fight, evading enemies and firing a dedicated laser.Support & Scaling: It helps collect hearts and scales its power directly with your ship's upgrades.Maintenance: When its HP gets low, the Wingman will fly back to your ship for automated repairs.New Arsenal: Smart BombsSometimes, the only way out is through. I am adding Smart Bombs as a secondary attack to help you survive those "no-win" scenarios. One press will clear the screen of projectiles and enemies, giving you the tactical reset you need.The siege continues... see you in June!
