Static lasers you can mess with. Stop them with your fingers, your hands, and real boxes: Quest 3 depth sensing scans your room so physical objects block the beams.
Hands: every finger bone blocks beams · pinch a laser emitter to pick it up and aim it (it stays where you leave it) · poke menu buttons with a fingertip · poke the red ring above your other wrist to show/hide the menu · pinch the menu's top edge to move it.
Controllers: point + trigger for the menu · B / Y shows or hides it · grip an emitter to move it.
Chill mode: lasers stop on you. Death mode: a laser touching your head/body zaps you (hands are safe).
Scanning: look around at your boxes for a few seconds. Found objects show as faint blue cubes (toggle with SHOW).
