Nice expansion for the Movies.
Yes the graphics are good, featuring nice vehicle models. The explosions are excellent and I don't remember any slow-down in the framerate. The on foot levels don't really look that good, but are decent. One of the most amazing things is the amount of enemies on screen, sometimes dozens of enemies tanks are all trying to blast you to kingdom come. A graphical success.
The sound has good sound-a-likes for the main characters and adds to the immersion. The blasters, well, they sound like every other star wars game. The sound of droids breaking and lightsabers humming sounds just like the movies.
The missions are linear but always varied. You'll fight on the wookie planet in the forrests as well as in deep snow. Or in a big...em, garbage dump. But anyways the missions will rairly repeat themselves and are good fun.
A multiplayer is available and is as good as single player. There's the standard deathmatch but also a protect the base mode. In this mode, (one of my favorites), you try to kill the opponents base, but can capture side bases for building AI allies. This gives lots of strategy to the game and is quite fun. Theres also a competitive co-op mode which is basically survivial. There are two levels for this, one in the Geonsis arena and another in a similer arena. The Geonosis arena has you playing as Jedi, allowing a minor force power. This is pretty fun but not as fun as the other, in which you are a tank or walker. This mode will last you a long time and is pretty difficult, requiring teamwork and skill.
I would suggest this game to any star wars fan, and to action fans in general.
