Complete every side activity in Gotham — crimes, AR Trials, the Riddler & Cluemaster puzzles and world events across all nine of Gotham's districts. It's the largest single post-story task. Activate each district's Tower (Batgirl hacks it) first so activities and collectibles show on your map, then work one district at a time using the map's activity filter.
- Stop 30 crimes across the nine districts
- Earn 5 Gold Medals in AR Trials
- Clear the Riddler & Cluemaster puzzles (see the Collectibles guide)
- Deal with the world events and villain hideouts as they appear
Nine Districts
Gotham is split into nine districts, opened up progressively as you play through the story. Each holds its own crimes, AR Trials, puzzles and collectibles. The key habit for all of it: reach and activate the Tower in each district (Batgirl's hack) — that pins almost every activity and collectible in the district onto your map, so the open-world cleanup becomes a checklist rather than a blind sweep. (Bat-Symbols are the one thing towers don't reveal.)
Stop 30 crimes across the nine districts. Crimes appear as red siren icons on the map — deal with 30 and the trophy pops. They respawn, so you'll comfortably reach 30 through normal play long before you've cleared the whole city.
- Activate each district's Tower and its crimes show on your map.
- A few crimes are gated behind a specific character's ability — swap heroes at the Batcave and come back if you can't start one.
You only need 5 Gold Medals in AR Trials for the trophy — not all of them. AR Trials are score/time challenges dotted around Gotham (traversal runs, combat gauntlets, target and vehicle challenges). Pick the five that suit you and replay to push your medal; the traversal and vehicle ones are usually the quickest golds.
These are the 121 puzzle boxes (60 Riddler + 60 Cluemaster, plus a final challenge) set across the city — the game's "Puzzle Rooms". They unlock once you've met Robin, and each is the same puzzle: slot directional tiles to steer a robot onto the checkered square, then hit the red button. Clearing them pays out WayneTech Chips, exclusive outfits and a Gold Skill Brick. Full breakdown on the Collectibles guide.
A crime-related milestone that comes naturally while you're stopping crimes for the trophy above — keep taking on the different crimes that pop up around Gotham and it unlocks on its own. Nothing special to set up.
An exploration/notoriety milestone you'll reach just by playing the open world — clearing crimes, trials and events across the districts builds it up until it pops. No special setup needed.
