Star Wars: The Force Unleashed II

For those having trouble with this achievement...I tried playing the first level over and over with only using force powers and following all the guides and still no success.

So I tried Cato Neimoidia "The Tarko-se Areana on EASY with maxed force powers (but maximum force powers is probably unnecessary) aka the Gorog fight mission.

The Gorog fight counts as an entire level. Use your force lightning on him and his restraints, just don't use your sabers. Chain him up twice like normal and you are ALLOWED to hit "the x button" during the action sequences (Both of them the one where you pull down the Gorog's head and the one where you stab it in the metal plate). Next, saber throw fully powered does NOT count as using your sabers. When you are trying to make the Gorog knock down the supports use force lightning and fully charge saber throws. Before using saber throws make sure you have force pushed all the random storm troopers out of the way so there are no "accidents" when your saber throw seeks a target. When the Gorog is gripping the supports use force lightning to get him to release. Finally the fall sequence. Again for some reason here saber throw does NOT count as using your sabers. I used a mix of force lightning and saber throws here. Do the rapidly pressing A action sequence and the achievement will pop shortly into the cut-scene.

Hope this helps anyone else that is frustrated by playing the first board over and over and the achievement not popping. Gooduck!

Update: Do not use your sabers to block. This solution seems to not work for everyone and the achievement is glitchy. If you have been having trouble with other solutions not working like i did then I really recommend trying this.

Ok. I've been trying this achievements on both recommendatory levels (Kamino and Arena), and I failed to get it either way.
I wasn't using anything but lightening and force push, and I was doing only single dash when needed.
I was so tired of this so I started a new game on the new save slot and got it on my first try!!

With this I can now confirm one thing for sure:
-QTE DOES NOT cancel the achievement. I did it on the first droid and still got the achievement.
- mind trick does not mess with it too.

So do this:
start new game within the new save slot - use only Y and B, and dash when prompted.
Use QTE on both droids if you may. You will have to use it on the first one, because you won't be able to kill it, but with the second one - just through several containers into him and he'll be done.
If you will use only those skills, you will get this achievement.

Good Luck!

Best done on the first stage on Easy. When fighting the Carbonite War Droid, use Force Lightning and stay far away for it to launch carbonite and grip it to throw it back at the Droid. To kill it without doing the action, use Repulse when A is present abouve its head. Also throw some at Stormtroppers to get another achievement called Shattered. Zap the troopers to kill them. Other than that, this is easy.

Like "metalanda7x" said, this achievement done easiest in the first level and "Easy" difficulty only makes its easier. Environmental kills such as force pushing stormtroopers into a fan, throwing boxes at stormtroopers and killing them with it, deflecting laser bolts, throwing enemies into force fields, using the Kamino generators to play pinball with the stormtroopers, and many other ways do not negate this achievement. The only thing that negates this achievement is using your actual saber to kill enemies, this includes cut-scene saber kills such as the "Carbonite Droid" with the shield, do NOT kill him using the button sequences, just use your force powers. This achievement was confusing for me as I tried for it several times before it unlocked. Just be sure to use only your Force Powers and you''ll snag it a few seconds after the end of level cut-scene begins. Thanks everyone and enjoy this phenomenal game!!

Okay then, here we go! I had found myself searching all over the Internet for solutions to this achievement. In my opinion it appears to be broken. However, this does not mean it's unobtainable. I have come to the conclusion that certain methods work for certain people. It appears to be completely random. I will now share my method. Please bear in mind, this is the method that worked for me! .....................................................................
First off, return to the main menu. Then you will need to create a new save file. Creating a new save file was the only way I could unlock this achievement. Start the game on easy difficulty. You must avoid pushing the X button at all times. When you get to the big guys holding the shields you CAN use the force to remove the shields. Tapping A in this sequence will not matter! Well it certainly didn't for me. Moving on, when you detach their shields you then have to spam Y (Electric) It will take a few minutes, but please be patient as it will eventually kill them. Kill all other storm troopers with what ever power you want. JUST AVOID USING MELEE. Do this throughout the whole level and kill the big guys my way. With a bit of luck you will unlock the achievement. I can't prove that this will work for everybody, but it sure is another solution worth trying. NOTE: It was the method I used. Feel free to comment if needed. Please let me know if this works or not. Good luck.

If you are having trouble with this - Start a New Game, play Level 1 on Easy. Use only Force Push and Lightning as offense. Use Grip and Dash when prompted. Also, for the Robots you can press A and do the quick action events to kill it because it is impossible to kill it with level 1 skills in lightning and push*. I didn't block, nor swing light saber during normal combat. Just got the achievement doing it this way.

* I killed the first Robot on the training grounds using quick action event, however for the second robot, I weakened it til it prompted for me to press A, then I gripped crates and boxes, hit them with lightning, and then threw them at it for the kill.

This is the guide which will nabb you the Use the force Luke achievement......

Level/Mission 1, Easy......go.

First fight sequence use force moves too.

Go through the whole level only using FORCE powers (B,Y,RT,LT+Y etc), Dash can be used through the whole level. Make your way to the end.

REALLY IMPORTANT INFO BELOW!!!!!!

When fighting against the huge machines with the shields, just disarm them then throw everything you go at them (litterally or just kick their arse, not using the Sabers) when your prompt to press A.....DON'T DON'T DON'T....Just keep hitting them with Force moves or GO UNLEASHED with Left and Right them sticks (press them together) once your bar at bottom left is completely purple and kick their arse that way.

WHY NOT USING THE PROMPT BUTTONS?!?!
It says press X after pressing A. Doing the assassination sequence will not allow the achievement to pop.

This will defiantly get you that achievement on your first attempt.

Completed on lvl 1. My hypothesis is: when you use LT, if a bolt is deflected back at an enemy, that is counted as a saber use and the achievement won't unlock. I tried for this achievement about 5 times on lvl 1 and it finally unlocked for me only after making sure that I used the left trigger as little as possible. The three storm troopers that emerge with the mech-like machines need to be killed first to avoid an accidental death by a deflection when/if you perform force repulse near the mech, and with something other than lightsabers, then you can do the quick time event of force-gripping the shield away from him. But DO NOT do the last quicktime event when his health is low.

I think my problem was when I went to do a special power like force repulse, I would hit the LT and a blaster bolt would accidentally get deflected back and either hit or kill a stormtrooper. So to sum up; don't use the X button, use LT as little as possible because you could accidentally kill something with a blaster bolt, and you CAN use the quicktime events of taking the mech-like machine's shields away but DO NOT do the last quicktime with them when their health is low, kill the machines with normal force powers after the shields are ripped away.

I used force push with maxed powers as much as possible, but mind trick and lightning will also work. I just didn't want to accidentally hit the x button!

So there are alot of rumors floating around out there about what you can and cant do for this achievement. I got this on my first try while playing "Kamino - The Return" I used saber throw, i parried and when fighting the red force guys, I used the Y+B grapple and just force pushed them out of the air to kill them. I also did the QTE for fighting the shield guys. I dont know if this is glitched for people, but from my experience, as long as you dont just push X when fighting, you should be able to get this.

Just a little addition to the already existing solutions. After the first level and the arena fight did not work for me in any suggested variation (no QTE, no dashing, etc) I realized that I used a saber crystal that enhanced my force abitlities (yellow for the lightning). After I removed them and used the standard two (red without any bonus) it worked on the first try on the arena level (with dashing in the falling sequence). It would also explain why for others starting a new save file worked. Because you obviously start with the red saber crystals only. I don't know if this actually influences this achievement but I thought I share my experience nonetheless. Hope this helps somebody with this annoying chievo.

EDIT: I started the level with my yellow crystals equipped and changed them in the opening sequence where you talk with Kota that you cannot abort.
