SUMMARY — Easy to understand, addictive to play

Ozone Guardian is a modern take on the classic arcade shooter with colourful stark visuals and equally addicting gameplay.
You defend the ozone layer against groups of evil spaceships, which increase in quantity and power each time, and you're thrown at a large menacing boss every 5 rounds.
Your dodging and timing skills reward you with higher points at the end of the round, which you spend on creative Upgrades in the Space Shop to boost your spaceship's capabilities. Whether you enjoy burning foes with damage over time, launching shuriken shaped blasts, shooting 4 shots simultaneously in a cone, piercing through enemies or firing at hit-scan speeds, the Shop has your creativity covered.
With thousands of combinations, your choices matter in your spaceship's growth and will affect your experience moving forward at harder rounds. Purchase power in small increments each round, or save your points to large amounts to see the Shop offer some higher-level supreme upgrades.

You can choose to play a quick session on-the-go (casual, 5-10 minutes), experience the normal gameplay at its best (normal, 25-30 minutes), or take on a harder realm to truly exercise your precision (hard, ~1 hour).
Enjoy our assortment of soundtracks to soothe your session, or get invigorated with an upbeat tune.

Save your best gameplay session on the global leaderboards and see how you fare against others around the world, in any category!

And all for the price of a cup of coffee.
