“In one of the most expansive LEGO video games to date, players become Chase McCain, a police officer who goes undercover to hunt down the notorious, and recently escaped, criminal, Rex Fury, to put an end to his city-wide crime wave. This open-world LEGO adventure allows fans and newcomers to explore the sprawling metropolis that is LEGO City with more than 20 unique districts to investigate, filled with car thieves to bust, vehicles to navigate, mischievous aliens to capture, hilarious movie references to discover, lost pigs to rescue and of course, hundreds of collectibles. With 15 special assignments to conquer, LEGO City Undercover brings together witty, original storytelling with signature LEGO humor to create a fun-filled experience for players of all ages.” - from LEGO.com
LEGO City Undercover was first released for the Nintendo Wii in 2013. This is the first LEGO game for the Xbox to have a setting based on an original LEGO theme. The structure is somewhat different than what you’d expect from a LEGO game, but the core gameplay is the same.
Instead of going from level to level with a series of smaller hubs to roam around in between, this game has one giant hub (LEGO City) and you play the chapters from within. It’s very similar to open world games such as Grand Theft Auto where you have the entire city at your fingertips. Often you have to perform tasks in each chapter before starting a level, called ‘Special Assignments’. Plus, most of the time, you can roam around the city doing other things during each chapter before continuing the story. You’re not limited or forced to go from level to level as in other LEGO games.
NOTE: For this guide, I will be using the terms ‘Special Assignments’ and ‘levels’ synonymously as they mean the same thing.
You will unlock all the disguises for Chase McCain throughout the course of the story. Doing so gives you all abilities except for one (Super Strength). Here is what each disguise does:
- Civilian - No special abilities
- Police - Detective Scan (track footprints, audio, camera), Grapple Gun, Arrest Gangs and Vehicle Robbers
- Robber - Crowbar, Stethoscope, Color Gun, Smash ATMs, Vehicle Robberies
- Miner - Pickaxe, Dynamite, Destroy Precious Boulders and Silver Statue
- Astronaut - Ray Gun, Astro Box, Teleporter, Jetpack, Capture Aliens, Conquer Districts
- Farmer - Watering Can, Egg Shooter, Chicken Flight, Flower Box, Return Pigs
- Fireman - Fire Extinguisher, Fire Axe, Rescue Cats, Extinguish BBQ Fires
- Construction - Pneumatic Drill, Electric Boxes, Drill Thrill, Coffee Break
- Rex Fury (any) - Super Strength (refer to “Pull the Lawnmower Over!” for location of token)
There are many useful red bricks found in this game, from ‘Unlimited Dynamite’, ‘Nitrous For All,’ the stud multipliers, ‘Invincibility,’ and ‘Super Fast Travel.’ Then there are fun ones like ring tones, ‘Wonder Whistle,’ ‘Costumes,’ and ‘Police Siren Hat.’ While you are required to find them all for “Cheat Chief,” you certainly won’t be using all of them.
Often overlooked red bricks are the ‘Data Scan Upgrade’ ones. When you find them, they are automatically turned on. With each of these five red bricks, they will make your collectible hunting easier and less tedious. When you press to enter data scan mode, depending on how many of these upgrade red bricks you’ve collected, they will show you certain things. However, the range is somewhat limited so you need to keep repositioning. Below is a list of the five bricks and what they do.
- ‘Data Scan Upgrade - Character Challenges’ - Shows Character Challenges that have not been completed.
- ‘Data Scan Upgrade - City Challenges’ - Shows the locations for Disguise Booths, Free Runs, Super Builds, Time Trials, and Train Stations.
- ‘Data Scan Upgrade - Clues’ - Shows clues and color gun locations.
- ‘Data Scan Upgrade - Red Bricks’ - Shows the locations of uncollected Red Bricks.
- ‘Data Scan Upgrade - Tokens’ - Shows the locations of character and vehicle tokens. This does not, however, show tokens that appear when you perform specific actions (like completing a puzzle).
Step 1 - Story Mode:
This game is structured a little bit differently than other LEGO games. While there are 15 chapters in this game, not every one of these chapters has a story level, called ‘Special Assignments’. Some chapters even have two Special Assignments in them. The chapters take place in the open world of LEGO City and often you have to perform tasks before starting a Special Assignment. Plus, most of the time, you can roam around the city doing other things during each chapter before continuing the story. In that sense it is a true open world game. The city is one giant hub.
Don’t worry about any collectibles or attaining ‘LEGO City Hero’ the first time playing as you cannot gather most of them through story mode anyway. Plus, you need certain character disguises to access certain areas of the level that aren’t available to you in your first playthrough. Just sit back and enjoy the story.
Note that the x2 red brick stud multiplier can be collected while playing Special Assignment #2, ‘Trouble in Stir,’ in Story Mode. After you complete that special assignment, it is available to be enabled (you don’t have to purchase any red bricks in this game). From then on, with each special assignment you play, you should attain ‘LEGO City Hero.’ Refer to “You’re a Legend!” for more information.
If you get stuck at any point and aren’t sure what to do next, refer to this YouTube walkthrough PLAYLIST by packattack04082.
Step 2 - Free Play Mode:
While playing through the story, you will unlock all 8 disguises for Chase McCain, and if you’re paying attention, collect the Rex Fury token in Special Assignment #15, ‘Fly Me to the Moon’. This will give you all of the abilities you need to obtain any collectible in the game. Refer to “Pull the Lawnmower Over!” for more information about the Rex Fury token.
After you complete each Special Assignment, Free Play becomes available for that level. It is recommended that you complete the story first before tackling Free Play as there are many collectibles that are only obtainable with disguises unlocked in later levels. Once you have completed the story, feel free to replay each Special Assignment in any order.
Each Special Assignment contains three gold bricks: completing the level (which you should have gotten in Story Mode), attaining ‘LEGO City Hero’ and collecting all four pieces of a police badge. In addition, there are two character and two vehicle tokens that count towards the 100%. Play through each level and complete them fully before moving on so you don’t have to backtrack and play it again. Once you’ve obtained everything in a level, you can press and select ‘Save and Return to LEGO City.’
For a 100% on each of the Special Assignments, refer to THIS VIDEO by packattack04082.
There are 305 character and 120 vehicle tokens to collect.
Character tokens are found in Special Assignments, when completing challenges, building disguise booths and Super Builds, solving puzzles, locating Skullptures and Hidden Police Shields and by completing various other tasks throughout the city. They are also found outright but usually in out-of-the-way locations.
Vehicle tokens found in Special Assignments, when completing challenges, locating train stations, building Super Builds, completing the vehicle bonus missions and by completing various other tasks throughout the city.
As stated in the previous step, the ‘Data Scan Upgrade - Tokens’ red brick allows you to see unfound tokens in the immediate area when you use your data scanner. It only shows tokens that can be collected outright; it does not reveal tokens that are awarded by any other means.
Step 3 - LEGO City (Hub):
There are 22 districts in Lego City. The entire city opens up and is available to you after you complete Chapter 4. For reference, boats are available after Chapter 7 and helipads are available after Chapter 10.
Unlocking train stations in each district allows you to fast travel to different areas quickly. While this is very convenient, they go to specific locations, so in order to get to your destination, you may still have to travel a short distance.
Each district has collectibles and gold bricks to obtain through a variety of character challenges, puzzles and races. If you are wanting to find out how many collectibles and challenges are in each district, when you are looking at a specific district on the map (press or after pressing ), press and it will show you a checklist grid of everything there is to collect and complete for that district. This is useful if you are completing everything by district instead of by category.
To access Lady Liberty Island, you need the Rex Fury character, so you need to have collected his token in Special Assignment #15. When you've collected it, in the circular fort in the Downtown district, there is a box that requires Super Strength to break open with Rex Fury. Once open, build the teleporter and use your Astronaut character to teleport to Lady Liberty Island. Once you land on the island, it will be accessible.
For a 100% video walkthrough of all the Special Assignments and City areas, refer to this PLAYLIST by packattack04082.
Glitch Note: As of the writing of this guide, you might come across a glitch that does not allow you to select a helicopter when you are at one of a few helipads. I personally have only come across this glitch at the helipad on top of the police station, but it might happen at others. The glitch is that when you access the helipad to select your helicopter, it doesn't allow you to select one and you cannot exit out. The only course of action is to exit the game and relaunch (losing any progress since you last saved). It doesn't affect any achievements; it's more of an annoyance. Best bet is to avoid using that particular helipad. The next closest one is at the hospital.
Step 4 - Mop Up & 100%:
If you haven’t unlocked the remaining achievements, now is the time to do it. Other than the level completion, challenge and collectible achievements, there are roughly 15 random achievements to unlock (that don’t count towards the 100%), ranging from car surfing, using 10 stunt ramps in a taxi with a passenger, collecting 4 billion studs or scoring 3 baskets in 3 attempts while playing basketball, just to name a few. All of these can be unlocked in the city itself. Refer to each solution for the quickest way to unlock these.
To see what percentage you have, press and it is at the top of the screen. Make sure you purchase every character and vehicle (which can be done from disguise booths, call-in points and helipads), acquire all the gold bricks, and so on. Use the bullet list in “Super Compuper” as a checklist and make sure you’ve obtained everything. Once you do, that achievement will unlock.
This is one of the more enjoyable LEGO games. LEGO games can be a tedious completion, but if you stick with it, you’ll get 100% in no time! Enjoy!
