The upcoming classes so far up to date on the upcoming Star Wars the Old Republic game for the Sith Empire are

• Bounty Hunters
• Sith Warrior
• Imperial Agent
• Sith Inquisitor

 The Bounty Hunter class

If you like to be a royal tough guy wearing heavy plated gear and using groovy gadgets. The Bounty Hunters for the upcoming game have a lot to offer, they are a very good class for recon missions and can no doubt run away from detection. Having the good old flamethrower and blaster pistols always comes with the job, however, with your combat moves and tactics you are able to kill Jedi just as good if you were like a Dark Jedi as well.

Their affiliation lies with the highest bidder, not all Bounty Hunters are loyal to the Sith nor Republic, however the methods you use can be ruthless except you do anything it takes to get the job done one way or another.

 Sith Imperial Agent

This class is very good for recon missions, if you love the sniper rifle I'm sure you would love to have this handy in your own way. This class is good for disguising yourself during missions, or of course if you want to avoid detection the good old stealth mode should do the trick. The key thing about this class is mainly used for infiltration behind enemy lines and good for esponarge missions, however your also are a key assassin.

 Sith Inquisitor Agent

The Sith Inquisitor is considered to be a secret group who have been scheming politics and dark secrets. Unlike the Sith Warrior, the Inquisitors seek to tap futher into the dark side of the Force discovering incredible destructive abilities and are able to use it for their own purposes. Ally or not, the Inquisitors are able to manipulate their powers and use it for their own purposes. Even though the Inquisitor is a Sith class and you get to see the true dark nature of the Force used against your allies or opponents, forbidden knowledge of the dark side of the Force will be exploited before your own eyes.
