Main Sewer Junction is not a place where Batman can simply sprint in, grab everything, and leave. The classic first-pass 100% sweep gets punished here, because the vertical maze hides Line Launcher and Ultra Batclaw gates and leaves Batman stalled short of all 30 Riddler Challenges. In proper Aslume fashion, the route looks obvious until the player meets a top-level gap that cannot be crossed yet. The smart plan is to handle gliding lines, sewer Batcave access, and cleanup in a deliberate order, so nobody performs the same doomed lap twice.

Read the Vertical Maze Before Chasing Trophies

Start at the top of Main Sewer Junction’s central pillar, then chain grapple boosts into long Cape Glides across the crumbling stone walkways. The movement loop is simple but unforgiving: grapple high, glide far, and land with enough space to launch again. Players should treat Glide Kick as an enemy-transition tool when thugs occupy the landing zone, not as the main traversal answer. It is great for crashing into a fight, but it will not solve the caves’ geometry.

The Ultra Batclaw is the real route-opener. It tears down high-altitude walls, opening gliding paths and the sewer route back toward the Batcave. That means the first pass should focus on vertical access and gadget gates, not on forcing every collectible into one lap. Save the massive upper gap until after the Party sequence grants the Line Launcher; the Batcave’s high-ledge trophy also requires it. For the highest cave exits near Arkham Mansion, grapple upward first and glide long rather than trying to climb every ledge directly. Batman has wings for a reason. 🦇

A practical route looks like this:

1. Grapple to the central pillar and use Cape Glides to scout the upper walkways.

2. Break high walls with the Ultra Batclaw and open the return path toward the Batcave.

3. Clear ground-level rooms, tapes, and teeth without chasing the top gap.

4. Leave the Line Launcher trophies and the Batcave high ledge for the post-Party cleanup.

5. Return with the Line Launcher and finish the vertical routes in one confident sweep.

Collectibles Sweep: Riddler Trophies, Riddles, Tapes, and Teeth

For exact trophy IDs, puzzle angles, and tape locations, players should keep a reliable Batman: Arkham Asylum reference handy before starting the caves sweep. The area contains 30 Riddler Challenges, 5 Killer Croc tapes, and 20 Joker Teeth. Two trophy priorities stand out: Trophy #3 sits on the Batcave high ledge and needs the Line Launcher, while Trophy #4 hides behind the Pressure Control Access destructible wall and needs Explosive Gel.

Grab the Riddler Map in the Pump Room with the 2 elevators before leaving. It flags remaining caves collectibles on the HUD and stops the usual “one teeth set missing” cleanup nonsense. That single pickup is worth more than a dozen blind laps. 🗺️

Killer Croc Lair and the Final Cleanup

Before entering Croc’s Lair, collect Tape 4 in the Croc Access Tunnel. Walk only on floating crates and never run: vibrations alert Killer Croc, while a Batarang to his collar is the response when he surfaces. After the encounter, return to the Old Sewer and use the Batclaw for Tape 5. Then upgrade the Cryptographic Sequencer to Level 3 for Pressure Control locks, and revisit Main Sewer Junction with the Line Launcher instead of attempting the top-gap trophies early.

This order matters because the caves punish impatience. A player who tries to clear the high gap before the Party sequence will burn time, miss the Batcave ledge, and probably leave a teeth set behind. A player who follows the gadget gates in sequence gets a clean sweep with far less backtracking.

Version Check and the Best Way to Play in 2026

As of October 24, 2026, no new Arkham Asylum content changes the caves route or collectible placement between the 2009 original, Return to Arkham, and current trilogy releases. Before buying another copy solely for a caves cleanup run, compare current price trackers against GOTY and trilogy sale listings; community reports cite Steam discounts as low as $2.99. Choose Switch for portable Aslume laps, PS5 or Xbox Series X|S for Return to Arkham convenience, and PC for GOTY pricing plus static-recompilation discussion. No publicly verifiable data is available for an official static-recompilation release. The Arkham Trilogy is available on Switch, PS4/5, Xbox One/Series X|S, while GOTY remains on Steam and Epic Games Store.

In short, Main Sewer Junction rewards a patient two-pass plan: open the vertical maze, collect everything that does not need the Line Launcher, then return after the Party sequence for the high-ledge trophies and the final Batcave cleanup. That is how Batman avoids the doomed lap and leaves the caves with all 30 Riddler Challenges accounted for. 🦇✅
