To do this certain trick u must choose space mission and aquire a spaceship(preferably a LAAT or trasport veichle).After you keep on taking off and lianding until when u land u don't see the shield(can take some practice).when u get out youll just be outside the hanger.if u want to goof off the,AI(computers)will spawn and you can push them off to a legde were u u can walk on.if u fall off u lose health but its worth it.b a clone piolet and gather in a group of soldiers and place the time bomb to self-suicide!!its fun if u try it.another way to hav fun is aquaire a scout ship(republic starfighter etc)and hav a peer keep the door to the internal place open.and speed ur way in to see how far you can go in the internal place.
