The Jedi Temple DLC pack for the Force Unleashed is a quick fun way to add-on to the experience, but the price tag on it makes it not worth it.
The "Jedi Temple" DLC requires you to start a new game to do the mission, you cannot jump to the level from your current game. This already creates a hassle. I had trouble finding the DLC at first. The Apprentice actaully has all the upgrades for the mission, so at least you have a maxed out character. The story of the DLC is also not that interesting. It is simple you go to the Jedi Temple to discover more about yourself and really who you are. While in the Jedi Temple it is a lot of fun. Many things can be destroyed. It is awesome to throw StormTroopers into object and watching them crumble apart. The Jedi Temple also is a very interesting level to be in. The Temple is in shambles from it's destruction at the hands of Skywalker. So it is very interesting to be in the place.
This DLC is hard to recomend. If you had a lot of fun with the game, this add-on only add to that fun. If you did not or are tired of the game, this add-on can not be recomended. It is simply too expensive for what you get. Probably only an hour or more of more play.
