From the README

Space Invaders, brought up to date and taken into 3D. Built in Unity 6 (URP). Your fighter guards the Earth from low orbit, and the invader wall marches toward you through space instead of down the screen. Invaders peel off and dive at you, regroup into new formations when you start winning, and every fifth wave a mothership arrives.

No download needed. It runs on any desktop browser (Chrome, Edge or Firefox) and needs a keyboard or a gamepad.

Linux: run ./build.sh once, then ./play.sh.

play.sh checks free GPU memory first and refuses to start below 1.5 GB (set MIN_FREE_MIB to change this).
