Very fun to play but has some issues
You play as a Twi'Lek mercenary with a robot partner. The game is mostly action but has some puzzles on them as well. There are some parts on which you should use turrets (on ground and in space), there is lot of jumping and some missions that I could say are like racing. On them you have to turn left or right and evade some obstacles.
The difficult is OK, there are some parts which can be finished easily with others hard that require a lot of practice and patience. Like the final boss… He's tough, but once you figure out how to kill it, you find out it's not that hard.
There's just one thing I don't like. It has some issues regarding paths. You can send your partner to do certain things, but if you encounter an obstacle, your droid won't get anywhere. Also, there are some parts on which you have to be in a certain place to be able to send your partner… Once you get used to it, you learn the way of how to send your partner in the correct manner.
With the lack of Star Wars games for the PSP, this one is a very good option and less "childish" than Lego Star Wars. I definitely recommend it while we wait for The Force Unleashed.
