This teaser is simply the mostest awesomenessess
It has come to our attention that one of Lord Vader's emotionally conflicted "Starkiller" clones has escaped. Again. We are currently unable to acquiesce to any transfer requests, and advise troopers who encounter Vader's twirling pet to remain calm, even in the face of his terrifying "dual-wielding" of lightsabers (see: ELEGANT WEAPONS chapter in "CIVILIZED AGES, THIRD EDITION"). Firing upon him is foolish and is not recommended under any circumstances whatsoever. Note: A self-inflicted wound from a deflected laser bolt will NOT count toward your appalling accuracy rating.

If an encounter is unavoidable and you somehow survive, you will most likely require medical attention. Be sure to bring any severed limbs to the medical bay along with your person. While it is preferable that arms and legs match the serial number of the torso, there is some degree of convenient interchangeability offered by the fact that you're all clones. Complaints of mismatched items being "gross" will not be tolerated.
A playable demo for Star Wars: The Force Unleashed 2 will be released on PSN and XBLA on October 12, LucasArts has confirmed.

"The level focuses on the very beginning of the game, which takes in a secret cloning facility on the planet of Kamino," explains Lucas.
"Starkiller, told by Vader he is no more than a clone, becomes tormented by the memories of his past and escapes into the rain-soaked planet with Vader not far behind. Unleash the power of dual Lightsabers, over-top Force powers including the new Jedi Mind Trick."

Sounds cool. The full game will be out on Wii, PS3, 360 and PC on October 26.
