A Watchful Collector Trophy in LEGO Batman: Legacy of the Dark Knight

Collect all Collectibles

Gold trophyBase game

The game counts 674 collectibles: 100 suits, 30 vehicles, 200 WayneTech Caches, 170 Batcave Trophy pieces, 23 Red Bricks, 30 Gold Bricks and 121 Riddler and Cluemaster puzzles. Bat-Symbols are not part of it. None of them is missable.

Story levels: each level gives you a fixed pair of characters who can reach all of its collectibles. Replay a level from the Batcomputer in the Batcave to pick up what you missed. PSNProfiles' Level Collectibles Guide has a screenshot of each collectible in the story levels.
The open world: after the story, hack each district's radio tower as Batgirl. It marks every collectible in the district on the map. Point at a district on the map (Touchpad) to see what is left there.
Suits, vehicles and Gold Bricks come from story levels, side activities and Bat-Mite's shop. Clearing every side activity, buying out the shop and buying the vehicles in the Batcave garage finishes them.
