Introduction
It has been a busy August for House House. Following the massive success of their latest co-op adventure, the development team has been steadily releasing patches to refine the experience across PC, Mac, PlayStation 5, and the Nintendo Switch 2. Today, we are looking at Patch 1.5.1, which brings several highly requested quality-of-life improvements, critical bug fixes for save files, and crucial adjustments to how the game handles audio mixing.
Since communication is the core puzzle-solving mechanic of this walker-talker, any tweak to the sound design or voice chat system has a massive impact on your expeditions. Whether you are coordinating a massive group using our guide on organizing massive 12-player expeditions or just exploring the Australian bush with a single friend, version 1.5.1 addresses several friction points that have been heavily discussed in the community over the past week. From annoying collision physics to terrifying save file corruption risks, this update touches nearly every technical pillar holding up the Wilsons Promontory-inspired open world.
Separate Volume Sliders for Audio Categories
The headline feature of Patch 1.5.1 is undeniably the addition of separate volume sliders for different audio categories. Previously, players had limited control over the granular mixing of sound effects, ambient noise, music, and the all-important proximity voice chat. The settings menu was a bit too minimalist for a game entirely dependent on hearing exactly what your friends are shouting from across a valley.
Because the game relies heavily on its unique voice chat system—where audio naturally attenuates over distance, echoes down corridors, and gets filtered through physical objects like walkie-talkies—having a unified or limited audio slider was occasionally frustrating. Players often found themselves struggling to hear their teammates over the howling wind on the higher peaks, or missing crucial environmental sound cues because the ambient noise of the coastal environments was overpowering their headset mix.
With the new separate sliders, you can now fine-tune exactly what you want to hear. If you have been struggling with vocal clarity, you can turn down the environmental ambiance and crank up the proximity chat specifically. This is a massive quality-of-life update that pairs perfectly with our previous troubleshooting advice on how to fix low voice chat volume. You no longer need to rely entirely on system-level microphone boosts or third-party equalizer software; the in-game tools are finally robust enough to handle diverse hardware setups across cross-play sessions.
The patch notes also reference ongoing adjustments to the specific item that “amplifies your voice,” hinting that these volume adjustments will play nicely with the game’s physical megaphones and amplification funnels. Balancing the volume of these specific items has been notoriously tricky since launch, as they could sometimes cause audio clipping if a teammate yelled too loudly into the receiver. The new categorical sliders seem explicitly designed to give players a way to mitigate these sudden spikes in decibels while maintaining the organic, spatial feel of the walker-talker genre.
Fixing the 1.4.9 Challenge Reset Bug
For completionists and hardcore puzzle solvers, the most terrifying bugs are the ones that threaten your save file integrity. Patch 1.4.9 unfortunately introduced an unintended issue where certain long-form challenges would reset themselves entirely after completion. More frustratingly, these reset challenges were no longer possible to finish a second time, effectively locking players out of full completion on that specific save slot and leaving friend groups stranded at 99%.
Patch 1.5.1 directly addresses this progression blocker. According to House House, saves made prior to 1.4.9 that were affected by this resetting bug should now function correctly moving forward. If you were one of the unlucky explorers who found their puzzle progress mysteriously wiped out, you can now safely return to the bush, load up your original save, and claim your missing milestones without starting a completely new run.
Reaching absolute completion is a massive undertaking that requires intense communication and dedicated session planning, so seeing your hard work invalidated was understandably disheartening. If you are currently pushing for that final percentage, you might want to read about the emotional depth of reaching 100% completion in Big Walk. It is a journey worth finishing, and thankfully, the technical roadblocks that threatened that finale have been permanently cleared.
Network Warnings and Password Quality of Life
When you are wrangling up to 12 players across Steam, PlayStation 5, and Nintendo Switch 2, network stability can occasionally falter—especially when players are joining from different continents. Previously, the game would offer a rather generic network warning when things got laggy, leaving hosts completely unsure if the issue was a slow internet connection (high ping) or an unstable one (severe packet loss).
Update 1.5.1 introduces distinct, specific in-game network warnings. The user interface will now accurately differentiate between a “slow connection” and a “connection that is unstable.” This diagnostic clarity is incredibly helpful for groups trying to determine which player might be causing physics desyncs or voice chat dropouts during a delicate puzzle sequence. If you want even more technical data on your screen while troubleshooting these new warnings, remember that you can always check out our tutorial on how to show FPS and ping to monitor your local situation closely.
Additionally, joining private lobbies has been made slightly less tedious. The password prompt shown when connecting to a game will now automatically clear itself after a failed attempt. It is a minor UI tweak, but when you are rapidly typing in codes to join a massive community expedition via Discord, not having to manually backspace a failed password is a welcome convenience. The wording on the host menu password prompt has also been slightly adjusted to be clearer for first-time lobby creators.
Physics Exploits and Item Interactions Addressed
Half the fun of this cooperative adventure is testing the limits of the physics engine and the physical items you carry around the island. However, some interactions were a bit too broken, allowing players to completely sequence-break puzzles, bypass locked gates, or accidentally lose vital equipment in the geometry.
One notable fix involves the mechanical turnstiles scattered around certain mid-game puzzle areas. Clever players quickly discovered it was possible to awkwardly reach over and pick up another player standing on the opposite side of a turnstile, completely breaking the intended navigation logic of the physical barrier. House House has patched this out, so you will actually have to solve the turnstile puzzles the old-fashioned way—through bickering, passing items through the bars, and trial-and-error, exactly as the developers intended.
There were also adjustments made to general wall collision across the open world. The patch notes state the developers have made it “harder to clip through certain walls.” While the speedrunning community might mourn the loss of these clipping exploits, it ensures that casual players won’t accidentally fall out of bounds, get trapped inside a rock formation, and lose their progress during a long cross-map hike.
On the item front, an annoying visual glitch involving backpacks has been fully resolved. Previously, placing certain items that display written messages into a backpack would cause the game to stop drawing shadows correctly, breaking the immersion of the beautiful dynamic lighting system. If you regularly act as the designated pack mule for your group, you can refer to our guide on how to find and wear a backpack without worrying about glitching out the environment.
Furthermore, a bizarre networking bug involving disconnecting players and physical tools has been squashed. If a player holding the specific “item with an image drawn on it and a dowel on the other side” disconnected from the session unexpectedly, the item could end up teleporting and dropping on the wrong side of a solid wall. Losing a crucial puzzle piece because of a network dropout was frustrating, so this failsafe ensures the item drops correctly in the playable area when a connection drops.
Lastly, the confetti launchers are back in full working order. Some launchers were previously refusing to fire when triggered, ruining many hard-earned celebratory moments after a tough puzzle. You can now pop confetti to your heart’s content.
CJK Font Rendering Fixes for the International Community
With the game rapidly surpassing one million copies sold globally (as we covered in our sales milestone report), international localization support is more important than ever. Patch 1.5.1 fixes a critical text rendering issue specific to Chinese, Japanese, and Korean (CJK) fonts.
Previously, these specific fonts would sometimes hit an internal character limit in the game’s memory and flat-out fail to render any new characters on screen. For a game that relies heavily on text communication through in-game physical whiteboards, typing out signs, and message-bearing items, losing the ability to read your teammate’s language because of a rendering limit was a massive barrier to entry. This fix ensures that cross-cultural expeditions and global players can continue communicating seamlessly, regardless of the alphabet being used.
Final Thoughts
Patch 1.5.1 is exactly the kind of targeted, unglamorous, yet absolutely vital update a complex multiplayer game needs in its launch month. While House House has already stated they have no post-launch content planned in terms of new maps or DLC, their dedication to refining the base game and supporting the community remains incredibly strong. They are aggressively targeting the exact friction points that disrupt the core “walker-talker” experience.
By giving us better control over our audio mix, securing save file integrity, improving network diagnostics, and smoothing out physics interactions, the Australian bush has never felt more welcoming. Be sure to download the 1.5.1 update before your next session, as all 2-12 players will need to be running the exact same version to connect via cross-play and explore together.
