Star Wars: The Force Unleashed II

The other 2 guides are great, just wanted to post the Achievement Hunter link for all the fans of their videos. Happy holocron hunting to all my fellow Warsies.

There aren't any holocrons on level 4.

If anyone needs additional help, there may be useful suggestions in the comments.

Credits for this guide goes to:
x360a, xThe Amory Wars, Silver Scorpian and Zorb and Kaiti

There are a total of 3 Holocrons. All of them are Costume Holocrons (Red).

1. Right when you start the level, turn around and go behind the stump.

2. When you are in the base and you have to lower the first walkway by throwing your light saber ( + ) and then Force Grip () it down, continue on until you make a left. If you walk forward a bit and look below you, you will see a Holocron on a walkway with the orange currents that injure you. Jump down on the walkway to grab it.

Note: You don't have to kill yourself to continue. You can use force push or force repulse to open an entrance on one side of the spherical power generator, force grip a power pillar up, then go inside and force push an exit before the pillar lowers back down.

As stated by meatman75 : Another quick way to avoid dying is to change your costume right after you get the holocron. The game will reload your checkpoint right before you have to press LT+X and pull the bridge down. And you will still keep the holocron.

3. The last holocron is right before the yellow-orange fences. When you come up to the part where you have to cross a long walkway with the orange currents on the floor and the yellow-orange fences that you destroy with force grip (), turn around and you will see a walkway above you. Jump on the small ledge in front of you and then jump up on the walk way. The holocron is at the end of the walkway.

There are 45 all together, I have pasted the guide from Videogamesblogger (i.e. they should get credit) just so it's one less link to follow. One thing to note, you can go back and replay the missions after you beat the game, the holocrons that you have already picked up will NOT be there, so you only have to worry about the ones you missed.

The Escape: 6 Holocrons

Holocron #1 Saber Crystal: Near the beginning. It is an unmissable holocron. It will be right above where you need to Force Grip the platform to get across the gap.

Holocron #2 Saber Crystal: Just after Holocron #1. It is another unmissable holocron, meaning it will be hard to actually miss this one. It will be right after you Dash through the 3 flames in the hallway at the end of it.

Holocron #3 Green Bacta Tank: Just after Holocron #2. It is partially an unmissable holocron. When you come across the circular walkway, it will be on a platform sticking out from the middle of it.

Holocron #4 Experience Point: It is an unmissable holocron. It will be shortly after the area with the 2 fans that you have to use your Force Grip to stop. Then once you drop down the vent and proceed down the hallway with the force fields you brought down it will be in the next room at the center of the console in the room.

Holocron #5 Experience Point: It is an unmissable holocron. It will be shortly after you use Force Grip to move a lift upwards to get onto the higher walkway. It will be floating above the large gap in the walkway right when the Imperial Jumptroopers show up for the first time in the game.

Holocron #6 Blue Bacta Tank: It is an unmissable holocron. It will be right after you battle the carbonite droid with stormtroopers. When you pass through the door, it will be on the left corner, grab this before proceeding to the right as a cutscene will start and blocking your way back to where you were.

Cato Neimoidia

The Eastern Arch: 8 Holocrons

Holocron #7 Saber Crystal: You could easily miss this holocron as there is no reason to go to this landing platform. Make sure to head to the empty platform at the beginning of the level on the opposite side of where you start before you head into the elevator after defeating the enemies. It will be behind a stack of crates.

Holocron #8 Experience Point: When you come across the transport platform, you will need to turn around and move 3 elevators to climb to the upper area to progress through the level. Climb to the right side to reach the XP Holocron sitting in plain site near the edge. If you go to the left side, you can still get this XP Holocron by walking all the way around.

Holocron #9 Saber Crystal: You will come to a point where you need to Force Push a door to bust it open. It will immediately be to the left as you exit through that door you just forced open.

Holocron #10 Saber Crystal: This one will be shortly after Holocron #9 and the next time you enter another room with a globe in the center of the room. Move the glowing globe with the force and grab the Saber Crystal.

Holocron #11 Blue Bacta Tank: It is an unmissable holocron but you may miss it while you jump because of the angle you are at and if you jump to early or late. If you do not get it, die right away and you will restart right at this same spot. If you get it, but die, it will still be counted that you got it and you can proceed to the next holocron and/or continue to play. It will be near the middle of the walkway as the gunship is shooting at the bridge destroying it as you move along it.

Holocron #12 Green Bacta Tank: It is an unmissable holocron. Once you Force Push through the door you will see it above walkway ahead of you with stormtroopers on each side of it shooting at you from a distance. Jump onto the empty platform and perform a double jump and dash to reach the walkway and this upper area.

Holocron #13 Experience Point: It is an unmissable holocron. It will be right after you drop down another elevator shaft and on an upper platform in clear site at the center of it.

Holocron #14 Costume Holocron: This is an easily missable holocron. It will be shortly after you drop down the last elevator shaft and when you encounter the entire casino floor with smoke. You will battle a Carbonite War Droid along with some Sith Acolytes and stormtroopers. Once you force push through the carbonite door, head all the way down and you will see a Jaba the Hutt hologram, destroy the 3 casino machines here and the Costume Holocron will appear inside of the hologram.

The Western Arch: 4 Holocrons

Holocron #15 Experience Point Holocron: This is an easily missable holocron. It is located right where you start in this level which is just after the cutscene from when you were on the transport. It will be behind the docking clamps.

Holocron #16 Saber Crystal: This is an unmissable holocron. It will be on at the start of the 3rd walkway you come across as you move through the area just after collecting Holocron #15. You will need to use one of the nearby crates in order to jump and grab it, as I show you before and after in the video. Holocron #17 is coming up right after this upcoming fight after collecting this holocron too.

Holocron #17 Blue Bacta Tank: This is an unmissable holocron. It will be in the room to the left as you first enter with the globe in the center just after the battle you fought with a Carbonite War Droids and stormtroopers.

Holocron #18 Green Bacta Tank: This is an unmissable holocron. It will be in the center of the walkway when you get to the last barricade with the Carbonite War Droid and stormtroopers.

The Tarko-se Arena: 2 Holocrons

Holocron #19 Experience Point: This Experience Point Holocron will be on the 3rd level as you proceed up the elevator. You will need to double jump and then dash towards this area to grab the holocron. You can stay in this area and jump down below to a small platform to grab Holocron #20. Watch the next video on how to exactly grab Holocron #20. Make sure to not stay on the elevator too long, as it will then lead you to a cutscene and to the actual arena where you will fight a boss. You will not be able to go back unless you later reply it.

Holocron #20 Saber Crystal: This Saber Crystal Holocron will be on the 2nd level directly across from where you start. If you are still at the area where you just collected Holocron #19 then drop down below to a small. Then perform a double jump and dash towards the 2nd level where the Saber Crystal is at. If you fall just rinse and repeat by taking the elevator up to the 3rd level. Make sure to not stay on the elevator too long, as it will then lead you to a cutscene and to the actual arena where you will fight a boss. You will not be able to go back unless you later reply it.

Dagobah

The Vision

Holocron #21 Experience Point: This is above the Rogue Shadow right where you start and exit from in the cutscene. Behind it will be a rock, use this rock to jump onto the Rogue Shadow and then just jump in the middle of it to grab the Experience Point.

Holocron #22 Blue Bacta Tank: This is right underneath the rock you used to climb onto the Rogue Shadow to grab Holocron #21. Just move the rock with the force to easily grab it.

Holocron #23 Saber Crystal: This Saber Crystal will be found once you jump out of the area you were in to the area above. You will see a hut ahead of you on the path; it will be to the right of the hut in the trees.

Holocron #24 Green Bacta Tank: This Green Bacta Tank will be underneath the rock ahead from the hut on the path to your left. This will be right before the next 2 Holocrons before you enter the hut and cutscene with Yoda.

Holocron #25 Saber Crystal: This is an unmissable holocron. It will be right along the only path you can take to enter the hut. This is just right after you grabbed Holocron #24.

Holocron #26 Experience Point: This is an unmissable holocron. It will be right in front of the hut before you enter it. It is impossible not to see and just right after grabbing Holocron #25 along this path too.

The Rebel Ship Salvation

Aboard The Salvation: 6 Holocrons

Holocron #27 Saber Crystal: This is an unmissable holocron. You will see it as you progress through a hallway to be able to progress on through the game. It will be right before the 2nd elevator you use to go down.

Holocron #28 Green Bacta Tank: You will come to a point in the game where you need to use a fuse to open a door to progress through the game. Instead of using it on the door right in front of you, take it down the hallway to the right from which you entered this T hallway from. There will be another door down this hallway and to the right. Use the fuse at this door instead to grab the Green Bacta Tank. If you have destroyed all the coolant tanks prior to this area, and destroy the 3 in this room as well you will unlock the achievement called “Master of Disaster” worth 10 Gamerscore or a Trophy.

Holocron #29 Blue Bacta Tank: It will be below where you enter the chasm for the first time. Jump to the platform across from where you entered and then turn around and look below that entrance ledge. It will be on the damaged ledge below that. When you jump on it, the ledge will start to fall so get out of there fast.

Holocron #30 Experience Point: This is an unmissable holocron. It will be on your way through the spinning machines that you have to get the timing right on to dash through. It is also just before where you drop down into the shaft below.

Holocron #31 Experience Point: You will find this one inside the engine room right in front of it on the piping. Just perform a double jump and dash to grab this, if you happen to fall you can still use the elevators on either side to get on top of the again, which you will need to use anyways to get out of the area.

Holocron #32 Saber Crystal: This Saber Crystal will be at the end of the level after you have defeated the Terror Walker and before you head to the next level for a cutscene.

Battle for the Salvation: 7 Holocrons

Holocron #33 Experience Point: This Experience Point will be in a small pod on the upper right corner room of the bay. You can get this holocron at any point before you move on through the door after clearing all the enemies.

Holocron #34 Green Bacta Tank: This is an unmissable holocron. When you come to the area with all the gears and engines it will be behind the engines in the corner that you have to destroy to proceed on with the level and just before where you jump down into another vent to the lower level.

Holocron #35 Saber Crystal: This is an unmissable holocron. It will be in the hallway just after the engine room as you proceed through the level. You will not be able to miss it and it is just before another destroyed chasm.

Holocron #36 Saber Crystal: This Saber Crystal Holocron will be in the bay that the War Droid came out of at the end of the hallway on the left.

Holocron #37 Blue Bacta Tank: This Blue Bacta Tank will be shortly after #36 after you have battled the War Droid and Imperial Squads. You will go through the only door that you need to put the fuse into. There will be a long hallway of stormtrooper snipers aiming and shooting at you. Take the first hallway to the left to reach a room you were in earlier but this time the Blue Bacta Tank will be in the broken tank.

Holocron #38 Experience Point: This will below the elevator platform in a vent-like area. You would have had to use Force Grip in order to move the broken elevator platform.

Holocron #39 Saber Crystal: This Saber Crystal Holocron will be at the end of the level. You will need to make sure that you get this before jumping onto the gunner and controlling it. Instead, go around the gunner to the opposite side of the room that is now open and stack the 2 crates you see in this area in the far corner so you can reach the holocron at the top corner of the room.

The Return: 3 Holocrons

Holocron #40 Green Bacta Tank: This Green Bacta Tank can be right at the start of the level. It will be on the pile of junk in front of you. Simply just jump on the pile of junk to grab it, this is also to the right of Holocron #41.

Holocron #41 Experience Point: This Experience Point Holocron can be found right at the start of the level just like Holocron #40. It will be to the left of #40 on another pile of junk. Simply just climb the junk from one of the sides.

Holocron #42 Blue Bacta Tank: This Blue Bacta Tank can be found right in the 2nd tower control room that you enter just after battling a War Droid and some stormtroopers. It will be in the left corner on the upper platform walkway. There will be a smaller platform for you to perform a double jump on to reach that area.

The Confrontation: 3 Holocrons

Holocron #43 Saber Crystal: This Saber Crystal Holocron will be found right near the beginning coming up after you have dropped down all the ledges outside. Before proceeding over the wall, make sure that you bring over one of the crates so that you will be able to jump onto the platform where the Saber Crystal is at, or else you will not be able to go back and grab a crate.

However, there is still a way you can respawn in the area before without replaying later. You will need to bring a Terror Walker that can be found near the end of this walkway on the other side, all the way to where the wall is located at. Then almost defeat it as you would with the action buttons but make sure you fail, and then the game should automatically spawn you on the other side of the wall allowing you to grab a crate this time and be able to reach the holocron.

Holocron #44 Saber Crystal: This Saber Crystal Holocron will be found when you take an elevator down to a lower level that puts you in a battle with an Incinerator War Droid along with spider droids. It will on the outer side of this circle and nearly unmissable.

Holocron #45 Experience Point: This Experience Point Holocron will be at the very end as you climb to the top of the spire on a stationary platform in a tank with 2 troopers that attack you. It will not be until you start climbing the platforms a 2nd time after a battle inside of it.
