If you have a save on your hard drive from the first Star Wars: The Force Unleashed, you will unlock two costumes: the Sith Stalker Armor and Training Gear.
During the first level when you must run away from the gun ship, when you stop you will die instantly. However, you'll also gain some Force Points. There's a save point here, so you can use a rubber band to hold down the character movement analog stick and create a perpetually running and dying Starkiller. You will earninfinite Force Points if you just leave the game and come back later.
