About

The skies are ablaze.
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.


Key Features

🔥 Intense Shoot-'em-up Action: Survive 50 escalating enemy waves and take down 10 bosses.

⚙️ Upgrade & Defend: Boost firepower, speed, and shields with power-ups. Block enemy fire with 3 defensive orbs, hunt foes with 4 homing missiles, and activate 5 planetary turrets.

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

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