Sometimes, against a crowded head, a minute in which only reaction counts does the trick. For that, the little collection of games among my tools now has Space Defence – a self-contained arcade game with its own figures, based on the gameplay of classic space shooters. It runs in your browser and transmits nothing.
At a glance
- Three ways to play: with the mouse (move, hold for continuous fire), the keyboard or the buttons on your phone.
- Fend off the formation: five rows of invaders move ever faster as fewer of them remain.
- Shields, bombs and a bonus mothership provide variety.
- Lives, waves and a best score – the best score stays only in your browser.
- Free and local: free of charge, free software, nothing leaves your browser.
How to play
Move your cannon and shoot down the descending formation before it reaches the bottom edge. Invaders in the upper rows score more points, the mothership that occasionally drifts past brings a bonus. Behind the four shields you are safe for a moment – but they crumble when they are hit. Once a wave is cleared, the next one comes, starting a little faster and lower.
In short
A short, fast game for in between – with its own figures and its own presentation, free of charge as free software under the GPL: Open Space Defence. Space Invaders™ is a trademark of Taito Corporation; this game is a self-contained implementation and has no connection to it.

Space Defence is a game for entertainment and relaxation during the short break.
