An expansion for JK2 that is solid, but also gives you a better insight into Star Wars universe.
I think that the most interesting thing here is the fact that you will fight your way trought the Sith temple and catacombs and that you will also play as Mara Jade, the former Emperor`s assasin and now a Jedi. As with the JK, you will also have the opprotunity to search for secret areas and will also have to solve various puzzles in the game - such as finding key for doors, using force powers to undercover buttons,...
Graphics have not significally improved, effects are little better. Sounds are more interessting, especially enemies and creatures ones.
I think, that hardcore FPS players won`t be so much impressed with this game, like they were with the last one, th JK2, expect Star Wars fans. Still I think that this is a nice addition to JK series.
