I've lost count of how many times I've booted up Batman: Arkham Knight, only to hit a wall on Miagani Island's last ten Riddle scans. It's 2026, and the Trilogy port is still the definitive way to play, but those scans? They're the bane of any 100% run. One missed Pinkney Orphanage scan, and my Knightfall protocol dead-ends. I learned that the hard way. So I stopped treating the collectibles as a checklist and started treating them as a route. With 38 trophies, 10 scans, 15 shields, and 3 bomb rioters all crammed onto one urban grid, I set my scanner to Up D-pad/X (on PC), trusted the Most Wanted totals, and accepted that route softlocks outlast any badge or suit update.

Ignore the scattered checklists. I now run these locations in a single sweep. Wayne Tower is first: enter Bruce's top-floor office and aim the scanner at the Wayne family portrait. Quick solve, no fuss.
Next, Elliot Memorial Hospital. Stand outside, aim up, and scan the bold front sign. Then head to Grand Avenue Station — climb to the upper floor and check both the Vicki Vale and Harvey Dent campaign posters. After that, Pinkney Orphanage is where runs go to die. Post-Catwoman, I scan her discarded collar on the floor and Riddler's headset/collar on his main desk. Don't overlook the Poison Ivy-linked flower/fan light fixture in the cell area. That one is a frequent stall for incomplete runs.
On the Mercy Bridge south side, I duck underneath, locate the Killer Croc shack and its circus poster collection, and scan for an easy riddle deduction. Near the Botanical Gardens, I find the Mr. Freeze refrigeration suit stashed in a store or lab. For Man-Bat, I aim at the "Hell's Gate" posters around the garden perimeter. Last, from a Grand Avenue skyscraper vantage, I line up Gotham's big Ferris Wheel in my scope and scan. That skyline unlock is one you must not skip.
Hidden Trophy Categories on Miagani Island
Trophy designs break three ways, and I've learned to recognize them on sight:
🦇 Batmobile puzzles: Look for Sonar-driven green icons, use the Power Winch for block pulling at Grand Avenue, and hit Mercy Bridge's generator after hitting roof ramps.
🔧 Gadget logic: Deploy the Voice Synthesizer for robot pressure plates, Remote Electrical Charge on wall generators, and Freeze Blast for persistent steam vents in the island's underground access tunnels.
⏱️ Timed platforming: Some plates trigger race lights — Grapnel Boost then Batmobile launch before the timer expires is mandatory. Failing once? Route again, do not retry blind.
Shields, Bomb Rioters, and Cleanup
I methodically blast the 15 Riddler Shields using the Batmobile's 60mm or Vulcan. I aim high on Wayne Tower's spires, Grand Avenue eaves, and tunnel mouths. Detective Vision sweeps for missed ones — no patch has altered their locations since the late 2023 Trilogy update.
Bomb Rioters appear in three specific Freeflow/Predator zones. I subdue, defuse, and confirm clear before leaving. If the tracker desyncs, I sweep back to all prior fights. I've validated this through Most Wanted statistics, and unlike some Brute informant routes, there are no random spawn anomalies here. Follow true completionist dogma: reconcile the in-game tracker with your physical map before exiting Miagani.

Platform Check and Final 100% Push
I grind Miagani on multiple builds — the definitive Arkham Trilogy on PS5, Xbox Series X|S, Switch (v1.0.3+), PC, and legacy Premium Edition. On PC, I always cross-check the official store page to ensure the current build, DLC installed, and correct skin unlocks before launching. For cost-sensitive purists, grabbing a legitimate license ahead of another true Knightfall run is smart, but the progression remains tied to WBID leaderboards and save flags, regardless of sale channel. No publicly verifiable data suggests collectible shifting since the 2023 port, but I always validate the version if I'm using unofficial suits like The Batman (2024).
So there it is. Ten scans, one route, zero dead-ends. It took me a few Knightfall restarts to get it right, but now Miagani Island is finally clean. If you're chasing 100% in 2026, don't leave that Pinkney Orphanage collar for last. Trust me — the Riddler is patient, but your save file isn't. 🦇
