Bioware have revealed the Advanced Class System for Star Wars: The Old Republic, which lets you customize your character skills to suit your specific gameplay style through a choice of one of two specialized careers.
"The Advanced Class System grants you access to unique skills and abilities, and is designed to allow you the flexibility to customize your characters to fit your play style. For example, all Smugglers are lucky, opportunistic swindlers. But, do you want to be the kind of Smuggler that sneaks into the middle of a firefight and quickly blasts away at an opponent from point-blank range? Or do you want to be the kind that keeps to the outskirts of the battle, strategically picking your targets from a distance?
These are just some of the meaningful choices that the Advanced Class System offers you to personalize - and advance - your character in Star Wars: The Old Republic!"
