Star Wars: The Force Unleashed II

You actually ONLY need to use dash to get this achievement. Just hit the LB button as quickly as possible once the falling sequence starts.

1. When you hit debris or stormtroopers while dashing this is not counted as a hit and you still get the achievement. Just got mine this way.

2. Also, if you are constantly dashing you get to Gorog quicker (that's where the achievement unlocks). In fact, when I was dashing I didn't even get to the big wall which has to be force pushed in the middle in order to pass. The whole sequence literally lasted a few seconds.

+1 to everything that has already been posted here, but I want to add one more tip:

The achievement is for REACHING the Gorog without hitting any debris. That means if you have already reached him and attacked him, are falling through debris again and HAVEN'T gotten the achievement, you won't get it and need to start again. This will pop the first time you catch up to him, assuming you avoided all collisions. I did this fight three times before that occurred to me and wasted a lot of time doing so.

The suggestion by Protium regarding the costume change WORKS, so if you even think for 1/10th of a second that you might have hit something, change your costume and start again. It's worth the extra ~15 seconds to not have to go through the whole boss fight again.

One last thing: you can get this achievement and "Use the Force, Luke" at the same time. Start the boss fight and never touch the X button, except during QTEs. If you mess up and accidentally use your sabers, you have to start the whole mess over again (sorry!). Assuming all goes according to plan, Stay on Target will pop when you first catch up to the Gorog during the fall and Use the Force, Luke will pop at the beginning of the cutscene.

Good luck!

i found a very easy way to get the achievement thanks to a loophole and here's how:

1. use force lighting instead of force push (clears out all debris and gets rid of storm troopers the same way as push but you can hold down the Y button for a constant stream of lightning)

2. dash whenever the screen is clear of debris; even if its just for a few seconds (make sure you try to charge as much as possible)

3. if you hit any debris outside of a dash change your costume and retry

LOOPHOLE: if you hit any debris during your dash just keep going. unless you take damage from crashing into debris it's not counted for some reason. not 100% sure if this is true but i hit a few rocks during my dive but i was in a dash and still unlocked the achievement.

if this does/does not work please let me know so i can take this down if i'm incorrect

During the fight with the Gorog you will enter a free fall sequence, at this time you will have to navigate towards the Gorog using dash to catch up.There might also be giant walls that come at you. Just use force push to break a hole to pass through. Once you have caught up to him a cut scence will trigger and the achievement should pop.

In my video i show how to get Stay On Target it is the fourth achievement i show in the vid and it starts at 2:39.

Just keep dashing through the debris, as dash does not count as getting hit, until you reach the Gorog and can start throwing you lightsabers at it. If you get hit anyway by debris, change costume to reload last checkpoint fast.

If you however get too close to the Gorog, ie get to throw lightsabers at it, and the achievements does not unlock, select Exit on the menu, then select Continue. Now you will start the fall from the beginning. Changing costume will only let you restart the part where you throw your lightsabers. Start dashing through the debris again.

It has been said that Exit/Continue does not work and you have to quit the game to the dashboard and start the game again. This is not true.

I dashed to the Gorog and started throwing lightsabers at it. But I must have been hit since achievement did not unlock. I chose Exit/Continue in the menu and restarted the fall from the beginning. Dashed through the debris and reached the Gorog again without getting hit - achievement unlocked.
