Video link [url=https://m.youtube.com/watch?v=3AZm-5NcJ0g&time_continue=329]Link[/url] Did someone try to put the combinations from the "ground symbols" [See video at 5:30] into the "ground light chamber"? You can see another combination at 5:45. There are some combinations on the ground, maybe you have to activate them in the light-chamber in a clock/counterclockwise order to get rid of the last laser grid? The ground-symbols match the ground-lights after all ... I can't test this now, would be helpful if anyone could (or tell me if you already did it and it didn't work).
