On Battlefront 2, go to any space level and get into a ship, then press the land/take off button repeatedly you should start moving forward VERY SLOWLY when part of your ship is penetrating the force field get out you should be on the outside, if not take off and land once more. It is also possible to get on top of the Empire's capital ship in this same manner. To do this first get into their troop carrier ship and press the land/take off button repeatedly. You should start to move. Once you penetrate the force field, continue pushing the land/take off button. You should eventually get above it. Then land and you can respawn there whenever you want. Also, if you land any ship as you are leaving the hangar, you will land outside the forcefield and be able to get out.
