There's one in the first five minutes of the demo - You can Force Drop a TIE Bomber on a bunch of dudes. And if you do it right, you can Force SMASH a TIE Bomber onto a bunch of dudes. Awesome.
The first five minutes of the game are even better. Darth Vader stomping around Kashyyyk and kicking unholy amounts of ass with the Force? HELL. YES.
Pick one. Slicing an AT-ST in half vertically? Blasting a Stormtrooper squad with a Force Wave and sending them into orbit? Deep-frying a rancor with Force Lightning after jamming a lightsaber into its face? Crushing a load-lifting Walker into a ten-foot-wide cube with the Force? Those are the minor ones! Forget "Moment", Galen is a Crowning Person of Awesome. The physics engine and Force powers are basically free license to make your ownCrowning Moments.
Rahm Kota's He's Back moment. Also, when he steals Palpatine's lightsaber out of his sleeve with the Force!
Kota does the latter twice in the novel, once with Starkiller's lightsaber when the rebel meeting was being ambushed by Vader and again with the Emperor's near the end of the game as mentioned above. It seems to be a trick he does.
"I did not summon him. His spies followed you here." The context of this is Galen returning from his final training test to see if he's ready to help Vader overthrow the Emperor. He shows admiration for Vader's cunning in summoning the Emperor to them, and is responded to with this line, followed by Vader's lightsaber going through his back.
A rare (for this game) moment where the awesome is in a cutscene as opposed to something you do. Starkiller prepares to board the Death Star. Sure that she'll never see him again, Juno pulls him into a kiss. After returning it, Starkiller jumps off the ship's boarding ramp and the music nicely fades away from the romantic theme to the ending of "Anakin's Dark Deeds" as Starkiller plumments through the Death Star's incomplete superstructure. He lands in a hangar as the hood of his new Lightside Jedi robes falls over his head. Just. Plain. Awesome.
This game has quite a few that don't involve absurdly abusing physics:
PROXY. Just...PROXY. He jumps Galen disguised as Obi-Wan, and later jumps him at the most inopportune time (intentionally) finally turning himself into Darth freaking Maul while explaining that he's deliberately withheld that particular program for all these years in case it took him years to accomplish his programming, so it would provide maximum surprise. He also pulls the Obi-Wan trick one more time against Vader on Corellia, buying Galen time to escape. He is quickly dealt with, of course, but his Heroic Sacrifice was still quite awesome, especially in light of his aforementioned attacks on Galen in the past. And the most awesome part is the choice of disguise, considering 'who'' is he attacking.
Perhaps Galen's best moment: dangling off a cliff as Vader explains that his scheme to overthrow the Emperor was just a ruse, Galen realizes how weak Vader really is. In spite of his close proximity to death, Galen throws this in his face: "Without me, you'll never be free."
Whichever way the game ends, Starkiller goes toe-to-toe with DarthVader himself. In the canonical light-side ending, he takes on Darth Sidious and fights him to the point where he has the Sith Lord at his mercy.
Think about it: Starkiller defeats Darth Vader, who has killed plenty of more experienced Jedi, taught Starkiller himself, and curbstomped him twice early on. Then, not 30 seconds later, he fights Palpatine and wins. Keep in mind, this is the guy who orchestrated the downfall of the Jedi and defeated Yoda.
Kind of subverted in the novel, however, which shows that Palpatine was merely pretending to be a weak old man in order to get Starkiller to embrace his hatred and join the Dark Side for good. It does hook Palpatine with his own CMOA in the Light Side ending, where Palpatine, despite being at the center of a massive explosion caused by Starkiller, seems like he's none the worse for wear, despite the whole area around him being absolutely devastated.
After destroying the shipyard at Raxus Prime, Starkiller uses the Force to bring down a Star Destroyer.
This scene also foreshadow's Kota's He's Back moment, as Kota gives Starkiller instructions like a seasoned general and Jedi Knight again instead of a drunk.
In the Ultimate Sith Edition, Lord Starkiller making Luke Skywalker fall, completely and utterly, to the dark side is both awesome and evil at the same time. He even tells Luke that giving into the dark side will save his friends and still comes out on top.
Lord Starkiller: You are strong, Skywalker, but only your hatred will give you the power to save your friends! Give in to the dark side! (Luke roars and fires Force Lightning, only for Starkiller to casually reflect it back at him) (Evil Laugh) Very good, my Apprentice!
Before that, Lord Starkiller tries to open the doors guarding the Millenium Falcon with the Force, only to find Luke Skywalker waiting for him. Luke Force Pushes him, knocking him across the room, then closes the doors with one gesture.
Toddler Galen Marek stealing Darth Vader's lightsaber with The Force.
In the novel, Starkiller pumping out enough Force Lightning to fill the entire planet Raxus Prime, completely erasing The Core.
Rahm Kota ripping the room out of the space station during his boss battle.
Starkiller throws Shaak Ti into the sarlaac's mouth. Is that the end of the fight. Nope. Shaak Ti reveals she can control the creature and rises to the surface on its tentacle.
The ending of the battle against Darth Desolous. Desolous spends the entire battle bragging about how he was such an awesome Sith Lord. Starkiller finally declares, "Your time is over, dead man! I am the future of the Sith!" and crushes Desolous with a statue.
Galen Marek jumping straight out of a tower and blasting Stormtroopers and TIE Fighters with the force. And this sequence ends with him landing in a research facility, instantly killing any hapless Mook who happened to be in there. Oh, and did we mention that this is the first sequence of the first level?
What makes this even more Badass is that Starkiller hasn't had anything to eat or drink in 13 days.
In the last part of his fight against the Gorog, Starkiller is shown to hold his lightsabers with the blades behind him, accelerate, and smash right through the Gorog. His blades were behind him. That means that he smashed through about thirty feet of Gorog with his lightsabers, the Force, and his head.
In the novel, Juno attacks Darth Vader with one of Starkiller's lightsabers and slashes him across the chest. A few minutes later, Starkiller pumps Force Lightning into the hole For Massive Damage (Vader's armor was upgraded to be more resistant to lightning later on).
While Juno missed in the actual game, the fact that she pulled a Shut Up, Hannibal! on Darth Vader remains awesome.
Even what she does in the game, grabbing one of Starkiller's lightsabers and attacking Vader with it, is enough for her to take a whole bunch of levels in badass. Just so it sinks in properly, this girl with zero Force affinity picked up a lightsaber and attacked Vader with it. The consequences are entirely predictable, but it was still awesome.
Starkiller using The Salvation to Colony Drop the cloning factory.
And how does he then survive going splat? He grabs onto a passing TIE fighter.
Starkiller and Kota facing the Gorog, a creature big enough to pick up a Bull Rancor and squish it.
Thesetwo tv spots for the sequel just define epic. Starkiller Force-choking twenty stormtroopers at once? Awesome.
Even if letting Vader live is a crazy idea, Kota's speech was amazing.
Starkiller: You want to take him prisoner?
Kota: To a hidden rebel base so we can interrogate him. To place him on trial for crimes against the True Republic! And then we'll execute him, to show the galaxy that we don't have to fear him any longer!
"I let you live. You tell me I'm a clone, but I chose to spare you. (beat) Maybe Kota's right. Maybe this is all a trick —a way to get me so confused... that I'd forget who I really am and become your slave again. But either way... I.Let. You. Live. I've finally broken your hold over me."
The main cannon of The Salvation has been damaged & knocked offline, so what does Starkiller do? Use the Force to supercharge & fire the weapon, blowing a hole through a Star Destroyer in the process.
Even better, that line woke Juno up from her coma.
In the comic, Boba Fett finishing off the Gorog, taking on Kota and PROXY (who turns into Jango Fett) before escaping and killing the Evilutionary Biologist who made the Starkiller clones (as well as clones of Boba himself).
The entire first mission. It begins with Starkiller not having ate or drank in thirteen days, then after a quick training session Starkiller remebers Darth Vaders betrayal of his previous self. So what does he do? He knocks Darth Vader on his ass, blows a hole in the wall jumps to the ground floor hundreds of feet down, fights his way through but loads of Imperial soldiers and equipment and then jacks Darth Vader's ride and escapes.
