Darth Vader

Ah Darth Vader. The main character of the Star wars trilogy.
After playing the Force Unleashed II I realised that Vader, despite being the main character, has rarely been a playable character in games. It's only in these modern times that Vader manages to get free of the boss battle chains and grabs hold of the playable character lightsaber. that didn't make much sense did it?
Well, I figured I would do some research and get you up to speed on the dark lords appearances as a playable character in a special post.

In a special download pack for this pretty good star wars game, Darth Vader appeared as a multiplayer character skin. However the dark lord seemed to be missing a glove and had a normal human right hand.

Vader was playable in the first level of this brilliant game, in which you took down multiple wookies and then got into a fight against a powerful Jedi knight. Also in the Wii version, if you type in Sith Lord (Please note I might have mispelt this) into the cheat code section, Darth Vader became unlocked as a special costume.
