Description
Galaxy Swarm: A Fast, Endless Space Survival Game for the Browser
Galaxy Swarm is a polished, top-down space shooter built with vanilla HTML5, CSS and JavaScript. There are no libraries, no frameworks, no build step and no backend to configure. You pilot an interceptor through an endlessly decorated galaxy, survive escalating waves of hostiles, and grow stronger with every run.
What Makes Galaxy Swarm Stand Out
The game pairs a sleek, modern look with a clear top-down view of the battlefield, so you can track enemies, plan your movement and time your attacks. Its vibrant colours and detailed visuals keep the action easy to follow, while the open-sector setting gives each run a sense of scale and discovery.
Key Features
- 5 unlockable weapons: Pulse, Beam, Spread, Piercer and Laser, each with its own attack pattern, so you can adapt to different enemies and situations.
- 8 ship skins: Customise your interceptor, from a classic silver design to the animated rainbow Prism livery.
- Persistent Ship Yard shop: Spend earned crystals to purchase, equip and manage weapons, skins and upgrades that carry across runs.
- Upgrade Tree: Invest resources between waves to boost your ship, weapons and abilities, and discover hidden evolutions named Phoenix, Voidstorm and Eclipse.
- 9 achievements: Chase mastery goals, see on-screen toasts when you unlock them, and track lifetime runs, kills and your best stage reached.
- Hidden constellation secrets: Find 8 departmental landmarks in the galaxy to unlock a secret Mogul ship class.
- Secret systems: Try the Hyperdrift orbit manoeuvre and enjoy automatic wide-angle vista camera moments while idle.
- Live attract mode: An animated battle sequence plays behind the main menu while you wait.
- Animated tutorial: New players are guided through the mechanics step by step, so the first run is easy to follow.
- Responsive design: Play on desktop, laptop, tablet or smartphone, with the layout adapting to your screen.
- Lightweight and fast-loading: Built for smooth, responsive play in modern web browsers.
