STELLAR GUARDIAN

Stellar Guardian is a free online 2D arcade space shooter where you take control of powerful spacecraft and fight through wave after wave of cosmic enemies to defend the galaxy. You pick your ship, manage your firepower, and push through increasingly difficult missions that test both your reflexes and your upgrade decisions. The core loop is simple: shoot, survive, upgrade, repeat.

What keeps this game addictive is the progression system. Between missions you unlock ship upgrades that genuinely change how you play, whether you focus on raw damage, speed, or survivability. The game includes multiple modes so there is always a reason to jump back in. For PC players, running the game in full screen eliminates any performance lag and keeps the action smooth. On mobile and tablet it runs well straight away, making it easy to pick up anywhere.

Stellar Guardian is a solid pick for fans of classic arcade shooters, retro space games, and anyone who enjoys free 2D shooting games online without downloading anything. If you grew up playing games like Galaga or enjoy modern browser-based shoot-em-ups, this hits the right notes. It also suits players looking for free space defense games, online arcade shooters with upgrades, or casual sci-fi shooting games they can play in short sessions. Jump in, pick a ship, and see how far into the galaxy you can push.
