Lego City Undercover isn't just "GTA for kids." Honestly, that comparison kind of does the game a disservice because it's way funnier and, in many ways, more complex than people give it credit for. If you’re hunting for a Lego City Undercover PS4 walkthrough, you probably realized pretty quickly that the main story is only about 20% of the actual game. The rest? It’s a massive, brick-built scavenger hunt spread across 20 different districts.
Chase McCain is back. He's got the hair, the quips, and a serious grudge against Rex Fury. But if you're just running from point A to point B following the green studs, you're missing the point. The PS4 version—which, let’s be real, runs way smoother than the original Wii U release—is packed with 450 Gold Bricks. Yeah, 450. You aren't finishing that in a weekend.
Getting Through the Story Missions First
Don’t even bother trying to collect everything on your first pass. It’s impossible. You’ll see a blue sparkling wall or a crate that needs a specific disguise and realize you haven't unlocked it yet. It’s frustrating. My advice? Blitz the 15 main special assignments.
These missions take you from the Albatross prison to the moon. Literally. Along the way, you'll unlock the essential eight disguises. Without the Fireman, you can't put out fires. Without the Farmer, you can't use the chicken glide. Without the Astronaut... well, you get the idea.
The PS4 version added a co-op mode that wasn't in the original. If you have a friend over, use them. It makes the "Special Assignment" puzzles move twice as fast because one person can handle the levers while the other stands on the pressure plates. It’s basic, but it saves time.
The Disguise System is the Real Gatekeeper
You’ve got your Civilian, Robber, Miner, Astronaut, Farmer, Fireman, and Construction Worker roles. Each one has a specific toolset. The Robber uses a crowbar to crack safes. The Miner uses a pickaxe to smash boulders and handles dynamite.

One thing most walkthroughs forget to mention: the "Color Gun."
You’ll find these swapper stations throughout the city. If a door has a green light but the sensor is red, you need the Robber's color gun to shoot it. But wait—you have to find the right color station first. It’s a circular logic puzzle that Lego games love to pull. In the PS4 version, the loading times are significantly shorter, so hopping between districts to find a specific color station isn't the nightmare it used to be.
Finding Rex Fury
This is the big one. To get 100% completion, you eventually need to play as Rex Fury himself. Why? Because he’s the only character with the "Super Strength" ability required to pull those orange handles you see scattered around the map. You don't unlock him until the very end of the game, after the final boss fight in space. Once you have him, go back to the earlier levels. Those orange handles usually hide the most elusive Gold Bricks and character tokens.
Navigating the Districts
Lego City is huge. You’ve got Cherry Tree Hills, Auburn, Fort Meadows, and the high-end Bright Lights Plaza. Each area has a set number of collectibles:
- Police Badges: Usually tied to mini-challenges within the level.
- Red Bricks: These are the holy grail. They give you cheats like "X2 Studs" or "Super Fast Build."
- Character Tokens: There are 290 characters. Most are just cosmetic, but some, like Rex, are functional.
- Gold Bricks: You get these for basically everything—finishing missions, completing races, and building "Super Builds."
Speaking of Super Builds, focus on the "Call-In Points" first. These allow you to spawn vehicles anywhere. It beats running across the bridge like a lost tourist.

Why the Red Bricks Change Everything
If you want to finish this Lego City Undercover PS4 walkthrough with your sanity intact, find the Red Bricks early. Specifically, the "Stud Multipliers." By the time you stack the x2, x4, x6, x8, and x10 bricks, every single stud you pick up is worth thousands. You’ll need billions of studs to buy all the vehicles and characters required for that 100% trophy.
The "Data Scan Upgrade" is another lifesaver. It highlights nearby collectibles on your map. Without it, you’re just blindly smashing trash cans in an alleyway hoping a gold brick pops out.
The Albatross and Blackwell Missions
The mission "Hot Property" at the Albatross prison is where the game really starts to pick up. You’ll learn how to use the Grapple Gun here. Pro tip: in the PS4 version, the camera can be a bit finicky during the parkour sections. Don't rush. The jumping mechanics are generous, but the depth perception can trick you.
Later, when you get to the Blackwell Mansion, you’ll need the Fireman disguise. There are hidden valves and fires that, if missed, prevent you from getting the "Master Builder" status for that level. Always look for the "hidden" areas behind the main path. Lego games thrive on putting rewards just off-camera.
Common Roadblocks and Glitches
Let’s talk about the 99.9% frustration.

A lot of players get stuck right at the end. Often, it’s a single "Cat Rescue" or a "Pig Return" mission hidden in a forest area like Bluebell Woods. Use the sensor on the PS4 controller—the light bar actually changes and the controller vibrates when you’re near a hidden item. It’s a small touch, but it’s actually useful.
Also, watch out for the "Super Build" in the airport district. Sometimes the bricks don't register if you're in a vehicle while initiating the build. Jump out, do it on foot, and make sure the animation finishes completely before you run off.
Moving Toward 100 Percent
Once the story is done, your map will look like a mess of icons. Take it district by district. Start in Cherry Tree Hills and don't move to Auburn until you've cleared every trial and collected every brick in that zone. It feels slower, but it prevents you from having to backtrack across the entire map for one missing flower pot you forgot to water.
Actionable Next Steps for Completion:
- Finish the Story: Don't stop to smell the roses. Get all eight disguises first.
- Unlock Rex Fury: Complete the final mission "Far Out" to get the Super Strength ability.
- Find the X2 Stud Brick: It’s located in the "Albatross Prison" area (look for the birdhouse).
- Buy the Jetpack: This is part of the Astronaut disguise and is vital for reaching rooftops in Bright Lights Plaza.
- Clear the Special Assignments in Free Play: Go back with your full roster of abilities to grab the 4 Police Badge pieces in every level.
- Use the Map Terminal: Check the police station's basement computer to see exactly which districts are missing collectibles.
Focusing on the multipliers first makes the "grind" of buying the expensive 1,000,000-stud cars much easier. The PS4 version remains the definitive way to play this, especially with the improved draw distance that helps you spot those glowing gold bricks from a mile away.
