Kluke will get kidnapped by Nene, you chase them to the cavern but can't make it across. You go to Pachess town and get stuck. After you escape from the green shield that encapsulates Pachess town in the icelands. You will cross the chasm with some help from a friend. Head Northwest until you see a crater, you will notice it because it goes from the white snow to the brown dirt. SAVE HERE. As you run towards the crater (avoiding the robots that surround it if you must). This will trigger a cutscene. Just as Kluke is thrown and you pan to Shu running towards the camera. A time pressed achievement will begin, you will need to hit a button when you are prompted on screen. It asked me to press on two separate occasions. I only did it once, so don't know whether it will remain the same.
