About Stellar Assault
Take control of a lone starfighter and survive 40 relentless waves of alien enemies hell-bent on your destruction. Choose from four unique vessels, the nimble Interceptor, the hard-hitting Destroyer, the evasive Phantom, or the heavily armored Dreadnought, each with its own stats and playstyle. Every wave you survive earns upgrade points. Repair your hull, boost your weapons, reinforce your shields,
Judged as a shooting game, Stellar Assault hits the notes you would hope for: enemies with distinct behaviours, ammunition or cooldown management and precise aiming. The skills it leans on are aim and target prioritisation; both improve noticeably after a few sessions.
How to play Stellar Assault
- Start by clicking the big play button. Stellar Assault loads inside the frame; give it a moment, especially on a slow connection.
- Follow the on-screen prompts. The developer describes the controls like this: Mouse or Keyboard Move WASD Arrow Keys Space Fire P Pause Resume M Mute Unmute
- Take a few practice shots at the first targets to learn the aim speed, then move on to prioritising the dangerous enemies.
- When you are comfortable, set a target: a score to beat, a level to clear or a time to shave. Small goals are what make Stellar Assault stick.

Tips and tricks
- If there is a reload, reload during quiet moments — never in the middle of a wave.
- Learn the spawn points. Most levels reuse the same few entry points, and knowing them turns panic into routine.
- Move between shots. Many shooters make you an easy target only when you stand in one place.
- Sound tells you where an enemy is before you can see it. Headphones help more than you would expect.
Who will enjoy it
We would recommend Stellar Assault to players who like precision, quick targeting and progressively tougher waves. In terms of time, think of levels of a few minutes each, with longer runs in survival modes. How hard is it? Approachable at first, with a steep climb in the later waves. It is designed for desktop play with a keyboard and mouse.
