LEGO Batman: Legacy of the Dark Knight has plenty for completionists to chase. Gotham is packed with collectibles, side activities, puzzle rooms, vehicles, unlockable suits, and Batcave upgrades. Reaching 100% is not just about finishing the story and rolling credits. You will need to explore every district, revisit missions, unlock characters, and clear a long list of optional content.
The good news is that many achievements unlock naturally while progressing through the campaign. Anything missed in story missions can later be revisited through the Batcomputer in the Batcave, which makes cleanup much easier.
One thing worth doing early is unlocking map targets by hacking towers with Batgirl. This reveals collectibles, events, and other hidden content across Gotham, saving a lot of searching later.
Story Progression Achievements

These achievements unlock simply by moving through the campaign and recruiting major characters along the way.
| Achievement | Requirement |
|---|---|
| “A legend, Mr. Wayne” | Complete the prologue |
| One Bad Day | Complete Chapter 1 |
| “Do I look like I’m joking?” | Complete Chapter 2 |
| The Dynamic Duo | Complete Chapter 3 |
| An Endless Winter | Complete Chapter 4 |
| Knightfall | Complete Chapter 5 |
| “A Hero Can Be Anyone.” | Complete Story Mode |
| A Friend | Unlock Jim Gordon |
| “Hear me roar” | Unlock Catwoman |
| The Boy Wonder | Unlock Robin |
| “Let’s see what Batgirl can do!” | Unlock Batgirl |
| A Grayson Graduation | Unlock Nightwing |
| Out Of The Shadows | Unlock Talia |
Most of these arrive naturally during story progression and require little extra effort.
Combat and Gameplay Achievements

Some trophies focus on combat mechanics and encourage players to experiment beyond basic attacks.
| Achievement | Requirement |
|---|---|
| “I am the shadows” | Perform 100 Stealth Takedowns |
| Caped Defender | Perform 100 successful Counters |
| The Strength To Fight | Reach a 99-hit Combat Combo |
| Cowardly and Suspicious Lot | Defeat every enemy type |
| “Lighter, faster, more agile.” | Unlock one upgrade from every skill category |
Stealth takedowns and counters usually happen naturally, though the 99-hit combo may require finding larger enemy groups.
Exploration and Gotham Achievements

Gotham itself hides a large amount of progress behind exploration.
| Achievement | Requirement |
|---|---|
| “It’s not exactly a normal world.” | Visit every district |
| “You’re becoming quite the celebrity.” | Discover 100 open-world events |
| “It’s a big city. I can’t be everywhere.” | Unlock all fast travel points |
| “Gotham can feel a little safer.” | Prevent 30 crimes |
| “Things have improved” | Prevent every crime type |
| “Is that like parachuting?” | Glide in 10 wind tunnels |
| “Hopefully because he’s busy” | Complete every side activity |
Fast travel unlocks become much easier once Batgirl begins hacking towers.
Batcave and Upgrade Achievements

The Batcave becomes increasingly important as you progress through the game.
| Achievement | Requirement |
|---|---|
| Rebuilding Gotham | Cash in a Batcave challenge |
| Not Just A Cave | Place five props or trophies |
| “No, sir. The OTHER car.” | Purchase three vehicles |
| Theatricality and Deception | Purchase three gadget upgrades |
| “I own the place” | Purchase all Batcave expansions |
| Wonderful Toys | Fully upgrade one character |
| Computer Privileges | Change the Batcomputer screensaver |
Batcave expansions require a significant amount of progress and resources, so expect these to unlock later.
Collectible and Completion Achievements

The largest section of the achievement list revolves around finding everything Gotham has hidden away.
| Achievement | Requirement |
|---|---|
| “The idea was to be a symbol” | Collect 25 Bat Symbols |
| “You have a name to maintain” | Open every WayneTech Cache |
| “Quite the collection, Master Bruce” | Collect all Batcave trophies |
| Too Many Questions | Complete every Puzzle Room |
| A Watchful Collector | Collect all collectibles |
| “I’m not wearing hockey pads” | Unlock all suits |
| “Wanna know how I got these cars?” | Unlock all vehicles |
| “Holy skill upgrades, Batman” | Unlock every skill upgrade |
| “This is too much power for one person.” | Collect all Red Bricks |
This section will likely take the longest. Many of these overlap with each other, so completing one often pushes progress toward several others.
Tips for Reaching 100%

Trying to clean up everything after finishing the story can create a huge checklist, so spreading progress out over your playthrough helps a lot. A few things make the process smoother:
- Use Batgirl to hack all Towers as early as possible
- Revisit story missions through the Batcomputer if collectibles were missed
- Complete crimes whenever they appear
- Purchase upgrades steadily instead of saving everything for later
- Explore each district before moving too far ahead in the campaign
Most achievements naturally connect together. Unlocking collectibles leads to new suits, vehicles, Batcave upgrades, and progression rewards.
Final Thoughts
Getting every achievement in LEGO Batman: Legacy of the Dark Knight is a long journey, but most of it revolves around exploring Gotham and interacting with everything the game offers.
By the time you unlock the final achievement, “I am Batman,” you will have cleared story content, emptied Gotham of collectibles, and turned the Batcave into a complete display of everything earned along the way.
