Narrative

Objective:

The objective of this video is to maintain and build a fan base for Star Wars: The Force Unleashed 2.

Setting:

The setting is on the cloning world of Kamino, which is why in the end you see the clones of Starkiller (main character) you understand that Vader cloned Starkiller.
The Setting is very much built to sell that it is kind of a realistic place, but it also built not to deter from the front ground and not to distract from the main characters.  It is built to be non-obtrusive.

Characters:

We have our protagonist, Starkiller; our antagonist, Darth Vader; many stormtroopers, a few large machines, and in the very end we have the Starkiller clones.

Narrator:

The Narrator is the voice of Starkiller.  He is explaining that Vader has betrayed him too many times and he is sick of being betrayed.  He is going to go rouge and find Juno Eclipse, the romantic character in the video game series.
While Starkiller is Narrating he has an angry tone in his voice like he is fed up with being treated like a tool of Vaders.  Also in his speech he has this overlaying tone of just cockiness, "Vader can't stop me. No one can."

Events:

I see three Kernels in this narrative.  (1) When Vader says he has no use for Starkiller and tells the troopers to kill him. (2) That Starkiller was escaping from Kamino. and (3) when we are taken down to the basement and shown the clones of Starkiller.
The first Kernel is both stative (Vader has no use for Stakiller) and active (Vader tells the troopers to kill him).  The Second Kernel is an active event; Starkiller is escaping. Third, is a stative event.  It states that Starkiller may think he is invincible, but look what Vader has up his sleeve.

Temporal Relations:

The entire narrative happens in just a few minutes.  The video is all in the now, but the narrator did give a flashback when he said, "Someone worth dying for."  That was a flashback to the first game talking about his love interest, Juno Eclipse.  Starkiller flashes back once again when he says, "betrayed by Vader for the last time."  giving the flashback and eluding to the fact that this isn't the first time that he has been betrayed by Vader, on the contrary, that being betrayed by Vader is a common thing and he is sick of it.
Other than these two flashbacks the rest of the story really just falls out chronological order in the few minutes it takes him to escape Kamino.

Causal Relations:

The biggest cause and effect relationship I can see in this narrative is Vader's betrayal.  Vader betrays and tries to kill Starkiller and the effect of that action is that he gets mad and escapes Kamino.  Smaller Causal Relations would be when machines or troopers attack Starkiller that causes the effect of him fighting and defeating them.

Audience:

This video was intended for gamers who had played the first game and were excited to learn more about the second game.  I would say it was made for all gamers, but in this video the narrator uses a lot of flashbacks of the first game and if one hasn't played the first game, then they would be lost to those references.

Genre:

The genre for this narrative would have to be romance.  Starkiller receives enlightenment that Vader really isn't a good master and he defeats his enemies and leaves Kamino victorious.  Sounds like a stereotypical romance genre narrative to me.
