Cosmic Invaders is a wave-based space shooter in the Space Invaders tradition. Formations descend, your barriers erode under fire from both directions, and a mothership crosses the top of the screen for bonus points. Accuracy is tracked per wave, so spraying shots costs you more than just ammunition.

Tips
- Your barriers are destructible and your own shots damage them too: firing through a gap you already made beats punching a new one.
- The saucer is the biggest single payout in the game. Badges exist for downing three in one run and for a single hit worth 300 or more.
- Accuracy is measured per wave, not per run, so a clean wave still counts even after a messy one. 50% earns Eagle Eye, 70% earns Sharpshooter.
- Clearing a wave without taking damage earns Untouchable, and finishing with 80% shield health earns Iron Dome. Both reward patience over speed.
- Waves 3, 6, 10 and 15 each carry their own badge, so there is a reason to push one wave further than feels comfortable.
