Tucked away in the back corner of SCEA's Pre-E3 Judges Day suite was a PlayStation 3 demo station featuring Linger In Shadows, an interactive, semi-playable technical demonstration designed by demoscene team Plastic. We showed the Linger In Shadows video back in March—but don't watch it if you want to avoid "spoilers"; it's pretty much the entire demo that will hit the PlayStation Network later this Winter.
But Linger In Shadows can't just be watched in full from the get go, it has to be unlocked. At certain moments in the demo, clues will be given to the player, indicating that some unspecified action needs to be performed. Miss it and the demo will rewind. The display then switches to a letterboxed mode and you'll be shown controller prompts that give you an indication about how to move on to the next scene.
