Achieving 100% completion in LEGO Batman: Legacy of the Dark Knight is a substantial undertaking. With 23 Red Bricks, 126 suits across 7 characters, 20+ vehicles, 250+ Batcave trophies, and 52 achievements, this guide provides a structured roadmap to maximize efficiency. As of launch week, less than 0.2% of players have achieved full completion — join the elite few.
Completion Roadmap
Follow this step-by-step plan for the most efficient path to 100%:
Play Through the Story
Complete all 7 chapters (Prologue + Chapters 1-6) on Caped Crusader difficulty. Don't worry about collectibles yet — enjoy the story and unlock all 7 playable characters. Approximately 10-12 hours.
Collect Red Bricks First
Replay each chapter in Free Play mode to find all 23 Red Bricks. These unlock game-changing cheats like stud multipliers, invincibility, and character detectors that make everything else easier.
Farm Studs with Multipliers
Equip your stud multiplier Red Bricks and farm studs in the Iceberg Lounge chapter. With all multipliers active, you can earn millions of studs per run — enough to buy all remaining suits, vehicles, and upgrades.
Complete Side Activities
Tackle all open-world events, crimes, AR Trials, and puzzle rooms across all 4 Gotham islands. Use fast travel to move efficiently between districts.
Mop Up Remaining Collectibles
Use the Batcave tracking system to identify missing suits, vehicles, and trophies. Return to chapters with the right characters to collect anything you missed.
Dark Knight Mode Cleanup
Complete any remaining achievements on Dark Knight difficulty. Some achievements require specific combat or stealth actions that are easier to grind in the open world.
Red Bricks — All 23 Locations
Red Bricks are special collectibles hidden in story missions. Each one unlocks a cheat code that can be toggled from the Batcave. Collecting all 23 is required for the "This is too much power for one person." achievement.

250+ Batcave Trophies & Props
The Batcave serves as central hub with over 250 displayable items. These come from:
- Story completion — Each chapter rewards Batcave trophies
- Side activities — Completing crimes and events unlocks props
- Collectible thresholds — Bat-Symbols, WayneTech caches, and more
- Shop purchases — Decoration themes available for studs
- Challenge rewards — Each challenge tier unlocks unique items
- AR Trials — Gold medals unlock exclusive Batcave decorations
Use the Batcave management screen to track completed sets. The Batcave decoration themes include: Gothic (default), Modern (unlock after Chapter 3), Classic (unlock after Chapter 5), and Holiday (unlock via special challenge).
Stud Farming Strategy
You need millions of studs to buy all suits, vehicles, and upgrades. Here's the optimal farming route:
- Collect Red Bricks #21-23 first — These unlock x2, x4, and x6 stud multipliers from AR Trials
- Equip all stud multipliers — x2 + x4 + x6 = x12 total multiplier (stacks multiplicatively)
- Also equip Stud Magnet and Attract Studs — Makes collection effortless
- Replay Chapter 2 (Schreck's Department Store) — Dense breakable objects and high stud density
- Break EVERYTHING — Smash all LEGO objects, defeat all enemies, collect every stud
- Average yield: 200,000-300,000 studs per 5-minute run with all multipliers
Total studs needed for 100% shop completion: approximately 2.5 million studs.
Skill Upgrades
Each character has four upgrade categories: Combat, Stealth, Exploration, and Utility. The "Holy Skill Upgrades, Batman!" achievement requires unlocking all upgrades for all characters — but achievement only requires 1 character fully upgraded.
Priority upgrades:
- Combo Extender (Combat) — Makes 99-hit combo much easier
- Silent Takedown (Stealth) — Essential for stealth challenges
- Grapple Boost (Exploration) — Faster traversal across Gotham
- Gadget Efficiency (Utility) — Reduces gadget cooldown
