Hey does anyone know what to do in HUB 3 right after you crash land on the planet? I'm wandering around right now trying ot figure out where to go next. Crysta

Ok i finally made it through the Language Labs and started up the Underground train. I activated the train and made to the stop. But now i can't exit the train. Do i have to wait for the door to open? How long does that take. I touched the controls again but nothign seemed to work. And also, why do none of the Supercharges or megaspheres work when i get them? I've found tens of them but all i get nothing when i pick it up. Crysta
