How to unlock the Mission: Accomplished achievement in LEGO Dimensions - Definitive Guide

Story Related and cannot be missed

Simply play through the Mission: Impossible level and you will receive this trophy once the level is complete. Below is a full walkthrough to complete the level.

American Embassy - Exterior

  1. Shoot the four flags in the middle of the area to reveal acrobat poles. Swing along the poles and climb the crumbling ledges to the area on the right. Keep in mind the game attempts to make this a stealth section, but does not offer much in the way of keeping yourself hidden, so tread lightly as possible to avoid combat. If you are spotted there are usually not too many agents to fight.
  2. Pull off the grapple point on the gargoyle to construct a new climbing point and continue up and to the right. If you are able to sneak around the patrolling agent, do a stealth takedown from behind (tap when prompted) and proceed to destroy the objects on the balcony to construct a walkway to the next ledge.
  3. Use Ethan’s Explode Silver Objects ability to open the gate to the first of many fuse box mini-games. Simply take the fuse on a path from the starting position designated by a green dot to the exit point marked by a red dot without running into any circuit walls or running out of time (fuse will begin to burn up as you move) If you fail you can simply start from the green dotted entry point without any penalty
  4. Activating the fuse will open a door above and reveal a grapple point directly under a few patrolling agents. Grapple up, defeat the three or four men and enter the Embassy.

American Embassy – Main Hall

  1. Pull off the grapple point to the right and destroy the glowing furniture to the left to construct your first Scan Disguise platform.
  2. Stand on the platform and a viewer will show a white haired man enter the room. Center the view on the man and tap until complete. Use this disguise to walk up to the scan station at the left of the door to gain entry to the Main Hall
  3. Enter the Main Hall and proceed to the middle level to meet Sarah. Access the device on the side of the piano to construct your second Scan Disguise platform
  4. Stand on the platform and focus your viewer on the guard at the top of either stairway (I found the right-side guard easier to capture) Take your disguise to the Security Access Computer to the left.
  5. Enter the elevator

American Embassy - Basement

  1. Once in the basement, use Ethan’s Stealth ability to walk over to the switch without getting caught by the camera
  2. After activating the switch, use Ethan’s X-Ray Vision ability to join the three red circuits together in the middle.
  3. Walk over to the newly revealed computer area and destroy the glowing objects. Construct a Technology device Ethan can access.
  4. The screen will quickly flash a direction on each of the three squares followed by a sequential series of numbers. Press the set of directions on your d-pad to solve the puzzle.
  5. Click on the three icons on the screen to open each video feed (it will always be the third selection) to find the mark.
  6. Take the elevator back up to the main hall

Streets of Prague

  1. Head up the stairs to the right and destroy the cart next to the large wooden gate. Destroy the Silver Lego covering to find a fuse box. Have Ethan complete the Fuse Box mini game, which will break apart the wall to Ethan’s right. Construct a ramp from the pieces.
  2. If you haven’t already, build the motorbike vehicle and save it to the Toy Tag. Use the Bike to jump through the large wooden gate
  3. Head to the left of the area to destroy some silver Lego bricks to create your first set of Magno Glove pipes (Bright blue glowing pipes)
  4. Destroy the door knocker to the left of the central stairways to find a Blue Paint Switch. Destroy the Juice cart next to it for the Keystone Selector.
  5. Pull off the grapple point on the cart next to the vehicle to construct a fuse box. Completing the mini game will move the car out of the way of the Yellow Paint Switch.
  6. Activate the Keystone and set Ethan on the corresponding spots on the gamepad when he is the correct color. Access the Red Paint Switch by climbing the Magna Glove pipes to the left of the area.
  7. When done correctly, Ethan will be able to climb the central stairs and construct a Grapple point which he can pull off the unnecessarily large lock to enter the next entertaining cut-scene

Street of Prague – Bar Fight and Streets pt. 2

  1. Destroy the objects surrounding Ethan during the fight to construct a grapple point on the right to pull out a cart from the debris. Blow up this silver Lego cart and initiate the kitchen doors to open
  2. Fight your way to the kitchen and access the Technology device to overflow the rightmost fish tank
  3. Construct a ramp out of the resulting pieces and use your motorbike (or any vehicle) to exit the bar
  4. Head to the Silver statue to the right of the bar and destroy it to construct a vehicle activation ramp.
  5. Drive your vehicle on to the ramp, activate the awning and destroy the nearby objects to construct a climbing point to traverse the windows and street lights above
  6. On the next balcony you will find a trash bin. Destroy it to construct a fuse box game behind it
  7. Once completed the doorway will be opened, enter both doors to activate the next cutscene

IMF Headquarters - Exterior

  1. Destroy the silver objects on the left to construct a ramp. Use your vehicle to enter the area beyond the gate.
  2. Pull off the grapple point on the van. Use X-ray vision to flip the switch inside the van. Destroy the vent above the van. Construct an activation ramp from these pieces and drive up the ramp to open the garage to the right.
  3. If you haven’t done so yet, build the Mission: Impossible car and save it to the Toy Tag. Use this car to pull off the three hooks on the wall in the garage to reveal an Acrobatic Wall
  4. Jump up the wall and hit the switch to open the path for Ethan to push the giant plug into the outlet at the left.
  5. Construct the Keystone Selector and activate it. Jump to the platform above and destroy the glowing box. Construct the entry point for Ethan to use his Magna Gloves to cross over to the other building on the right and find the tear to call up the first use of drones in this level. There are also a few guards in this area.
  6. Guide the drone through the path to the Fire Alarm to cause a bit of pandemonium and open the IMF doors.
  7. Ethan will spawn directly back at the position at the beginning of the checkpoint and he will be able to construct and use a Scan Disguise platform. Focus your viewer on the Hazmat Suit character who should be crossing from the right area of the circle to the front doors.
  8. Once in the disguise walk up to the Security Access Computer and scan in for entry into the IMF Interior

IMF Headquarters - Interior

  1. Run through the turnstiles towards the back console. Use Stealth to access the Technology device against the back wall
  2. When using the device, move the red green and blue pieces so they match the position of each color on the color key to the right of the console
  3. Once complete you may take the ladder to the next checkpoint

IMF Headquarers – Ventilation Shafts

  1. Use the drone in the top pipe to move the laser barrier to the right. Pull off the grapple point on the floor and drop down. Use the drone in the pipe below to move the laser barrier back to the left and away.
  2. Traverse the now accessible Magna Glove pipes, avoiding the steam sprays as you climb.
  3. To the right, there will be two silver vents that can be blown up to construct an activation ramp. Use your vehicle to lower a large fan that will propel Ethan up to a new platform
  4. Locate the fuse box game on this higher platform and complete the mini game for access to the area on the right.
  5. Set your grapple on to the above hook and lower Ethan down avoiding the timed laser barriers. Once at the bottom, play yet another fuse box mini-game.
  6. Climb back up and turn the lever to turn off the steam and enter the next checkpoint


IMF Headquarers – Ventilation Shafts pt. 2

  1. Use the drone to open the foot switch on the left side. Use Stealth to sneak over to the console on the far right to destroy the panel and leave the foot switch accessible. Have Ethan either run from one to the other before time runs out, or select Franz to aid in activating both foot switches at the same time. This opens the central area where you will be surprised to find another fuse box mini-game
  2. Completing this final fuse box game will open up the floor in the middle of the room.
  3. Lower Ethan down the iconic white room, avoiding the lasers as much as possible. Half way down, in the center of the room directly above the spinning laser wheel, will be the easiest mini-kit to obtain in the level, so if you need it for the Wouldn’t have it any other way trophy - grab it, because it can be missed.
  4. Once at the bottom, use X-ray vision to turn the four pieces into the IMF symbol to initiate the cut-scene

Train Roof
In the event that you have never seen the movie and you want to be surprised by the twist, I will refrain from naming the boss character from here on out

  1. Head across the train car fighting the enemies and blowing stuff up as needed
  2. When you are grabbed by the boss, you will receive a prompt to tap and/or to free yourself from their choke hold.
  3. Drop down to the train car floor and hit the target to climb up to the second train section
  4. After your second boss encounter Ethan will be able to construct and then pull off a grapple point to drop into the train car below. Advance to the end of the car.
  5. Blow up the objects to access the drone pipe and use it to open a pile of Magna Glove Pipes to construct.
  6. Climb the pipes and advance to the third train roof.
  7. Combat the thugs and then move on to fight the boss to whittle down their health. Once they are incapacitated, grapple the front of the helicopter to initiate the final checkpoint

Train Roof - Tunnel

  1. Work through the enemies and head away from the screen towards the helicopter
  2. Move up to the helicopter and it will bang up against the tunnel wall and produce pieces you will need later.
  3. Battle the boss until they try to choke you again. Tap the indicated button ( and/or ) when prompted.
  4. Repeat the process of fighting your way to the helicopter through waves of enemies, this time being fired at from the helicopter as well.
  5. Approach the helicopter and receive another array of pieces and studs. Construct the catapult device and access the Technology Panel in the back to jump on for the final cutscene and end of level
