Landers - You will first need to turn on the power by going to the room with box and flipping the switch. Now go to the Widows Wine lander and use that lander to travel back to the Centrifuge. Now use the lander at Speed Cola. Then use the Stamin-up lander. Once you've done all three of those go back to the power switch and press the red button and now the rocket will go off. You can now go under where the rocket was and unlock pack-a-punch. if you have either of the ray guns, you can shoot the rocket and get a free double points.
