Major Update: Acid Rain, Collection Journal, Tech Tree Rework, and Multiplayer Room Codes

Dear Conductors,

This update brings acid rain events, a collection journal, room codes for multiplayer, a forward/reverse console, and an all-new Push interaction. We have also reworked technology blueprints and several core interfaces.

The game now supports Turkish, alongside extensive adjustments to the camera, Bandit Leader, Steam Deck, animal husbandry, fish tanks, inventory, train controls, map environments, and multiplayer synchronization.

Read on for the full update notes.

Camera Mode Improvements

Fixed the image becoming abnormally dark in camera mode.

When entering photo mode, the following visual effects now match the normal character view:

Ambient lighting Sky rendering Weather effects Post-processing effects

The camera can now move up to 500 meters away from your character.

At the maximum distance:

You can still move sideways along the boundary You can return to your character normally A “Camera too far away” message appears on screen

Also fixed rain effects staying around the character and forming an isolated column of rain when using the camera in rainy weather. Rain effects now follow the camera's viewing position.

Turkish Language Support Added

Turkish is now officially available, allowing more players to experience OxyRail in their own language.

Special thanks to the following channels for providing a Turkish translation pack for the game:

Hnd Gaming Demlenmiş Oyuncular

Also fixed some interface prompts and level displays not changing with the game language.

The Collection Journal Is Here

Recipes learned, seeds and crops discovered, and fish encountered during your journey can now all be recorded in the journal.

Crafting and Use

Unlock the journal at the Research Table, then craft it using:

Wood ×2 Leaves ×4

Left-click while holding the journal to open its pages.

Checking Collection Progress

The journal has four sections:

Food recipes Drink recipes Seeds and crops Fish

Each section shows:

Number unlocked Current total Discovered entries Undiscovered entries

Unknown content appears as “???”, waiting to be discovered on your travels.

Reading Item Information

Click an unlocked entry to view:

Item icon Item name Item description

Recording Discoveries

Discoveries can be recorded by:

Holding the item Viewing the item in a chest Viewing the item in a furnace Viewing the item in a fish tank or another facility

Discovery records are permanently stored in your save. Even if you later use, sell, or lose an item, its journal entry will remain.

New Fish Discovery Notification

The first time you catch an unrecorded fish, the screen will display:

The fish's name The fish's weight

The new fish discovery notification has also been redesigned.

Technology Blueprint Overhaul

This update reorganizes research content, its interface, and the pace of progression.

Technology Pack Research

Related technologies are now grouped into technology packs.

A single research action can unlock up to 4 entries Packs containing only one entry display that item directly Research links between similar technologies are clearer

Five Technology Stages

The five technology stages now use a clearer branching structure.

Complete a stage's core technologies to move on to the next stage Fill in other research branches gradually according to your needs You no longer need to finish everything in a stage before progressing

Blueprint Interface Rework

The new technology interface features light-colored cards, dimensional shadows, and drag-to-browse navigation.

Each status has its own indicator:

Green background: unlocked Red background: not yet unlocked Lock icon: prerequisites not met

Technology details show:

Unlocks Prerequisite research Required materials

Rebalanced Research Costs

The first stage still has a low entry cost.

Later stages gradually introduce:

Processed materials Circuit boards Small amounts of rare resources

This creates a clearer connection between exploration, production, and technological progress.

Existing Progress Preserved

Items unlocked in older saves will not be lost.

If a technology pack is only partially completed:

You can continue researching the remaining entries Research costs are calculated in proportion to the entries still locked You will not have to pay again for completed entries

Improved Interaction Feedback

Technology cards now include:

Hover feedback Click animations Click sounds

After successful research, the blueprint unlock notification will still appear in the upper-right corner as usual.

New World Event: Acid Rain

Rain can now occur in more map areas where rainfall is appropriate.

Each time the weather changes from clear skies to rain, there is a 20% chance of triggering an acid rain event.

During acid rain:

Players exposed to the rain slowly lose health Find shelter under a roof, floor, or other overhead cover promptly Once you are under effective cover, you will stop taking acid rain damage

Event rules:

Acid rain will not trigger again during uninterrupted rainfall Acid rain will not occur while another world event is active Areas where rain is disabled will have neither normal rain nor acid rain Acid rain does not currently corrode train structures

New Forward/Reverse Console

The new Forward/Reverse Console can be unlocked and crafted early in the game.

The Forward/Reverse Console independently controls the train's:

Forward movement Reverse movement

When changing direction while moving:

The train slows down first It comes to a complete stop before moving in the opposite direction The control lever reflects the current gear

The Forward/Reverse Console stays linked to the Central Console, keeping direction indicators more consistent when multiple players operate the train.

Train Collision and Braking Improvements

When the train hits an obstacle, only the first car now shakes. The cars behind it no longer shake at the same time.

Braking has also been adjusted:

Braking force increases with train speed The train slows down faster at high speeds It comes to a more stable stop at low speeds Reduced repeated sliding and difficulty coming to a full stop

Fixed the Iron Cowcatcher losing no durability when hitting certain obstacles.

Cowcatchers of all materials now take the appropriate collision damage.

Multiplayer Room Codes

Room codes have been added to multiplayer.

The current room code now appears at the top of the ESC menu and can be copied with one click.

The Join Friends page now includes a room code field, allowing you to join open rooms hosted by players outside your friends list.

Hosts can:

Set a room password Allow friends only Pause new players joining Remove room members after confirmation

Removed players receive a clear notification and cannot rejoin for the remainder of that room session.

Choosing Play Alone prevents other players from joining by default. The host can open the room later from the room management page.

Multiplayer Interaction and Synchronization Improvements

Fixed an issue where non-host players interacting with cabinets, cooking stations, and similar facilities would only perform the reaching animation without opening the interface.

Interactions under network latency have also been improved:

Fewer repeated reaching animations Interfaces no longer reopen automatically after being closed More reliable responses to interaction requests

Other synchronization fixes:

Fixed searched supply crates sometimes remaining only for the host and still being unusable after rejoining Improved synchronization when picking up dropped items Reduced lingering visuals and collision remnants from dropped items Improved multiplayer fishing float spawning, synchronization, and retrieval Reduced duplicate fishing floats and abnormal rod retrieval

Improved network stability when leaving rooms and cleaning up objects, reducing network manager issues when exiting or changing scenes.

Downed Teammate Synchronization Fix

Fixed defeated teammates still appearing to stand upright to other players.

Other players now correctly see:

The character's collapse animation The final downed pose State changes after defeat

Bandit Leader Fixes

The Bandit Leader's combat and movement have been improved.

Fixes:

The Bandit Leader now falls onto the ground correctly when killed, instead of floating The Bandit Leader can chase players and climb very steep slopes Reduced getting stuck on slopes and uneven terrain Fixed bow attacks from extremely long range failing to draw the leader's aggression

After defeat, the Bandit Leader respawns after 2 in-game hours and can be challenged again.

The remaining wait time is preserved when you save and re-enter the game.

Recipe Availability Changes

Defeating the Bandit Leader grants the Provençal Vegetable Stew recipe.

You will not receive another copy if you have already unlocked the recipe.

Once your affinity with the Bandit Shop reaches 100, it may sell:

Bamboo-Tube Rice recipe Sushi recipe

Each recipe costs 20 Oxygen Coins.

Steam Deck and Controller Improvements

Default Steam Deck and controller controls have been adjusted.

Basic Controls

View/Select now opens the backpack by default B is used to crouch, dive, and go back in menus Reduced accidental actions when opening the backpack

Map Controls

The world map now supports:

Panning with the left stick Zooming with LT/RT Displaying names of locations near the center of the map

Steam Deck multiplayer text fields can open the on-screen keyboard The room password popup has been enlarged for small screens

New Mechanic: Push

You can now push other players.

Move close to a teammate, aim at them, and press E to push them a short distance forward.

Rules:

You can push once every 2 seconds The push prompt is hidden during cooldown If holding an item, your character first lowers their tool Your character uses both hands to push After the animation, your character holds the original item again The player being pushed can also see the animation

The key for feeding teammates has changed to F.

Major UI Visual Upgrade

Several core interfaces now use lighter colors and rounded shapes to better match the game's overall art style.

Redesigned notifications include:

New fish discovery New technology unlock New recipe unlock Friend feeding notification

The fishing rod charge bar has also been adjusted in terms of:

Color Position Consistency with other interfaces

Loading Screen Improvements

Improved loading screen visuals for a more consistent overall style.

Main Menu and Language List Improvements

Replaced some display models on the game's main menu.

Models that are obsolete or no longer match the current style will no longer appear in the main menu scene.

Fixed the last language option being partially cut off when scrolling to the bottom of the main menu's language list.

The language list also received these improvements:

Adjusted spacing between options The entire row is clickable Clearer selection indicators Improved mouse scrolling Reopening the list automatically scrolls to the current language The list automatically follows the selected option when navigating with a keyboard or controller

Character Animation Fixes

Fixed the Deer character's left arm staying stiff while walking or running.

The arm now resumes its normal swing after waving, picking up items, and similar actions.

Added a transitional cinematic for the magician's animations, making the character's story flow more smoothly.

Large Planter and Fertilizer Fixes

The Large Planter has a new model that better matches the game's current art style.

A bottom surface has also been added, so soil is no longer directly visible from below when the planter is placed on a glass floor.

Fixed remaining fertilizer in planting pots disappearing after re-entering the game.

This fix also applies to:

Planting pots containing crops Empty planting pots that have been fertilized but not planted

Chicken Coop Visual Upgrade

The Chicken Coop has a more detailed new model.

LOD levels have also been added, using more appropriate detail at a distance to reduce the coop's impact on performance.

Animal Enclosure Upgrade

The Animal Enclosure has a new model with improved overall visuals.

The new model differs only slightly in size from the old one.

Animal enclosures in older saves will update automatically and usually will not need repositioning.

Also fixed animal care states sometimes reverting or being incorrectly overwritten after saving and re-entering the game.

Improved saving reliability for:

Fullness Egg slot status Growth progress

Fish Tank and Fishing Adjustments

Fixed sandworms and earthworms being unusable as fish tank feed.

They are now correctly recognized and automatically fed to fish when placed in the tank.

When catching the following non-fish items, you receive them immediately after reeling in, without entering the reaction minigame:

Shrimp Freshwater mussels Wood Other non-fish items

Regular fish still use the existing fishing challenge.

Inventory System Improvements

Improved quick-transfer rules between the hotbar and backpack.

Now:

Transfers from the carried-items area or backpack prioritize the hotbar Transfers out of the hotbar prioritize the backpack If there is not enough destination space, any items that cannot be transferred remain in their original slot You no longer need to click repeatedly for the remaining items

Also fixed fish tank quick transfers skipping the first row.

Building and Dyeing Fixes

Fixed adjacent dyed glass walls incorrectly displaying their default color after removing an edge floor or resetting that floor's color.

Glass walls now retain the correct color without needing to re-enter the game.

Fixed moving items through the radial menu while holding a Building Hammer sometimes triggering an unintended hammer strike and dust effect.

Decorations can now be placed on top of the piano.

Windmill Upgrade

The old mill building has been fully replaced with a windmill, making the area better match its actual function.

The new windmill includes interior space that you can explore upwards.

Small Water Tank Upgrade

The Small Water Tank has a new model with improved visuals.

The new model has a slightly larger footprint.

Small Water Tanks already placed in older saves will automatically update to the new model, so some conductors may need to reposition them.

The old model will not be retained because its appearance differs substantially from the current version's style.

Storage Facility Model Upgrades

The Medium Storage Chest has a new model.

Its size is unchanged, so Medium Storage Chests in older saves will update automatically without needing to be moved.

The Small Storage Chest has updated textures for improved materials and visuals.

It no longer stops automatically after playing one song.

Fixed oxygen tank audio sometimes continuing after you stop breathing oxygen.

Improved audio stopping consistently for these oxygen tanks:

Small Oxygen Tank Medium Oxygen Tank Large Oxygen Tank

Releasing E, moving away from the oxygen tank, or switching targets now stops the breathing sound promptly and synchronizes this correctly for multiplayer players.

Drink Fix

Fixed Spooky Juice having no stat values.

Drinking it now applies the correct effects.

Volcanic Lava Improvements

Improved how volcanic lava meets the ground, fixing areas where lava floated above or clipped through the terrain.

Also fixed lava appearing to float on its own before distant terrain was displayed.

Color Adjustments

Adjusted the game's default hue.

Removed the unusually orange overall tint, bringing environments, characters, and items closer to their intended colors.
