When the app starts, press to move over to ‘Library’ and select ‘Interactive Episodes’.
This is unlocked in Episode 6, ‘Failure to Launch’, Chapter 2, ‘Failure to Launch’.
Throughout the chapter, an image of a launcher will appear somewhere on the screen. There are 20 of them total. Some will be clear and in the open, others will be out of focus and difficult to see. When you see one, point at the screen and say “picture”, and Cooper will take a picture of it.
Method 1: To make this easier, every time the camera changes position, just point and say “picture”. Then you really have zero chance of missing any.
Method 2: To make this even easier than that is if you have a fan, position it right in front of your Kinect and turn it on full blast. The microphone will pick up the sound (instead of saying “picture”) and that will guarantee you don’t miss any shapes for this achievement. Works like a charm! This is the same thing you do if you play Guitar Hero and want the game to recognize vocals on the Beginner difficulty.
If you missed any, just watch the chapter again. The game keeps track of the ones you have found already, so just try and find the items that you missed the first time. If you used either of the methods above, you shouldn't have to play a second time.
The simplest way to unlock this achievement is using ‘Chapter Select’ to choose the chapter. When the chapter is over and the next one starts, just press , move over to ‘Stop’ and press again. The achievement will unlock when it is buffering. You can alternatively watch the entire episode, but that would be more time consuming.
