You've finally done it. Scarecrow is in a cell, the Arkham Knight's identity is common knowledge, and Gotham is—theoretically—safe. But then you look at that Most Wanted menu. There he is. Edward Nigma. He’s mocking you with a list of 243 challenges, and a decent chunk of them are buried deep within the Arkham Knight HQ.
Honestly, the Arkham Knight HQ is one of the most confusing areas to navigate once the story missions are over. It’s split into North and South sections, it’s multi-layered, and if you miss one elevator, you’re basically wandering around a dark shopping mall for twenty minutes. If you're aiming for that 240% completion (or just the "true" Knightfall ending), you cannot skip these.
Let's break down how to actually get these trophies without losing your mind.
Navigating the HQ: North vs. South
The biggest hurdle is actually getting back inside. You can't just glide through a front door.

The Arkham Knight HQ North entrance is near the Killinger’s Department Store. You’ll remember this from the story—it’s where you lowered the Batmobile down the massive fan shaft. To get back in, you usually have to drop through the manhole or go through the roof access.
Arkham Knight HQ South is a different beast. This is the area where the final confrontation with the Arkham Knight happened (the predator-style boss fight). To get back here, you need to head to the rooftop of the building on Founders' Island and take the large elevator down. Many players get stuck because they try to find a way from North to South internally, but a cave-in during the story prevents you from driving or walking between the two main hubs easily.
Solving the Most Frustrating Trophies
There are 21 arkham knight arkham knight hq riddler trophies in total. Some are just sitting on a planter, but others require you to be a master of the Remote Electrical Charge (REC) and the Remote Hacking Device.

The Infamous "Ball in a Tube" Puzzle
You'll find this one in the maintenance access levels. It looks like a giant vertical glass case with three circular paths. Basically, you have to use the Remote Hacking Device to rotate the internal rings so the trophy ball can fall to the bottom.
- The Trick: Don't just spam the hack. You have to time the rotation so the ball gains enough momentum to clear the gaps. If you're too slow, it just rolls back to the start.
The Turret and the Pressure Pad
In Level 5, there’s a trophy tucked behind a sentry turret. If you step on the pad, the wall grate opens, but the turret shreds you.
- Blind the turret with the Remote Hacking Device.
- Stand on the pad.
- Fire a Remote Batarang through the grate and steer it to the right to hit the switch.
- Throw another Batarang to pick up an electrical charge from the nearby sparks, then guide it back to the fuse box.
- Run in and grab it before the turret reboots.
The Memory Game
Down in the South Hall, Nigma has set up a literal game of memory. You have to use the Remote Hacking Device to flip tiles and match pairs. It's not "hard," but it's tedious if you aren't paying attention. Take a photo of the tiles with your phone if you're feeling lazy. No shame in it.

Why These Trophies Matter for the Ending
You might be asking, "Why am I doing this?"
In Batman: Arkham Knight, the "Full" Knightfall Protocol only triggers if you finish every single Most Wanted mission. This includes capturing Riddler. To capture him, you have to complete all 243 challenges.
The arkham knight arkham knight hq riddler trophies are unique because they feel more industrial. They rely heavily on the gadgets you unlocked late in the game, like the Voice Synthesizer and the REC gun. If you haven't finished the main story yet, don't even bother trying to get all of these. You literally won't have the tools to open the doors.
Pro Tips for the Hunt
- Interrogate Thugs: Look for the guys glowing green on Founders' Island. If you don't see them, try flying around the GCPD or the shipping yards. They will mark the exact locations of the trophies on your map, which saves you hours of blind searching.
- Check the Map Levels: The HQ has five levels. When you’re looking at your map, toggle the d-pad to switch between floors. If a trophy icon looks like it’s in a wall, it’s probably just on a different floor.
- The Power of the Batclaw: A lot of these trophies are stuck to ceilings or high walls. Always look up. If you see a green glow, the Batclaw is your best friend.
Getting every trophy in the HQ is a test of patience. It’s dark, the layout is vertical, and the puzzles are some of the most technical in the game. But once you hear the satisfying "click" of that final cage opening, you're one step closer to putting Nigma behind bars and seeing the real end of Batman's journey.
Your Next Steps
Stop wandering the tunnels aimlessly. Your first move should be to check your map for the "South" elevator on the Founders' Island rooftops—that's where most people miss their final three trophies. Once you're inside, prioritize blinding any sentry turrets first so you can solve the environmental puzzles without taking chip damage. If a door is locked with a keypad, the password is almost always something tech-related like "Semiconductors" or "Robotics."
