Begin a new file, and enter your name as '' Wampa Stompa''. There is one space before Wampa, and two before Stompa. The name is case-sensitive as well. Make sure your controller is set to the Traditional setting.
Now enter the Battle of Hoth and play through until AT-STs join the battle. Press left on the control pad and right-C at the exact same time, then press up on the control pad. Then, press right-C to scroll through your camera angles. The over-the-shoulder view of your snowspeeder should now be replaced by that of an AT-ST. Use the control pad to move the AT-ST, and press up on the control pad to fire its cannon.
