Orbital-Siege

Orbital Siege is a chaotic orbital space shooter where you defend a solar system against endless waves of invaders.

Slingshot around planets using real orbital physics. Build momentum, line up your shots, and watch chains of enemies erupt into golden particle storms.

How to Play

• WASD / Arrow Keys — Thrust (but mostly just use the W. 
• Mouse — Aim & shoot
• Space — Drop bomb
• Shift — Boost (speed)
• Tab — Cycle weapons

Features

• Orbital physics — Fly in orbit around planets and use gravity to your advantage
• Chain explosions — Clusters of enemies blow each other up in cascading particle storms
• 50 named bosses across 3 tiers, each with unique mechanics (shields, charges, laser sweeps, minion spawns, and more)
• Solar bombs — Charge your bomb by flying close to the sun, then unleash devastating area blasts
• Weapon refits — Unlock different ship loadouts as you progress: Interceptor, Broadside, Lance, and more
• Escalating waves — Every wave brings more enemies, tougher formations, and new planet discoveries
• Pure HTML5 — Runs in your browser, no downloads or plugins needed

Tips

• Use planet gravity to slingshot into enemy clusters for maximum chain reactions
• The sun damages enemies too — lure them in close
• Solar bombs are most effective against large groups — save them for dense waves
• Boss "RESISTANT" types can only be destroyed by pushing them into the sun
• Chrome or Firefox recommended for best performance
