Read the changes01 / Development
Under the hood.
A look at what's synced,
and ready to play now.
Multiplayer systemsStatus
Implemented; local checks
Connections & world join
Spacewar supports one host and three guests. Steam P2P and TCP LAN currently support one host and one guest, with shared-world joining and reconnect handling.
Vehicles & Rivett
Driving handoff, installed seats, doors, engine audio and controls across supported vehicles; Rivett adds mechanical parts, fasteners, wiring and operating state.
Rally & prepared save
A separate prepared Rivett world, three timed stages, personal entries, penalties and rewards. Players take turns in the original Rivett; full four-player rally acceptance remains open.
PSK, shops & restaurant
Shared stock, orders, deliveries, fuel transactions, parked cars and music, with payments attributed to the requesting player. Concurrent and late-join cases remain under test.
Jobs & factory work
Taxi, original-Gifu sewage, kilju, wood and Futufon have dedicated shared flows. Factory clock-ins and validated work contributions feed individual wage shares.
Repairs, inspection & banking
Fleetari service requests, inspection outcomes and personal banking have explicit contracts. Full native service journeys and concurrent transactions still need acceptance.
Bus, train & world actors
Bus, train, road traffic and bound NPCs share movement, presence and supported audio. This does not include every native pedestrian or schedule.
Police & player interactions
Individual crime, pursuit, sirens, fines and jail paths; shared items, footsteps, towing, glass scraping and custom F7 dialogue have dedicated bindings.
Story & progression
Saved world state and specific live progression paths are shared. Remaining native missions, schedules and unbound interactions still need individual coverage.
Menu, skins & managed mods
Seven tabs organize Play, Worlds, Character, Settings, Imports, Mods and Community. Reduced motion and a standard cursor are available. Approved face, shirt and trouser PNG skins transfer with size and hash checks.
Rivett adjustable parts
Brake regulators, rev limiter, four race-shock bump/rebound controls and supported tachometer settings follow part identity through installation and removal. Native starting and mechanical rules remain in place.
Flea-market resale
Shared rental and listings use individual seller ownership and saved earnings, including offline sellers. Legacy listings with unknown sellers require explicit assignment. Retail purchases and fireworks retain their existing synchronization.
Coverage reviewed 26 October 2026. Status describes implemented systems; local checks and four-account acceptance are tracked separately.

Local checks passed; four-account acceptance is the next test session.
What changed 23 feature highlights
- 20 pumpkins · 500 mk each
- Explore 20 saved, randomized hunt locations. The first valid collector receives 500 mk; shared progress and individual rewards survive reconnects and later sessions.
- A pub worth finishing the hunt for
- Collect all 20 pumpkins to unlock the completion display and a short shared lantern-and-music celebration at the pub.
- Teimo’s Halloween makeover
- Halloween clothing, lanterns, signs and new interior/exterior textures dress the pub for the event while its native characters and interactions remain in place.
- PSK roads and pub decorations
- Six stationary pumpkins line the PSK road verges and four small pumpkins decorate Teimo’s pub. These are scenery; the 20 reward pumpkins remain a separate hunt.
- A haunted winter atmosphere
- A colder, darker colour grade and supported depth haze reshape the daytime atmosphere while preserving the snow, native weather and gameplay lights. Strength is adjustable.
- Ghosts and brief on-foot encounters
- Shrouded ghosts appear near the family home, apartment and pub. Occasional short on-foot apparitions use safe exterior ground, respect menus and focus, and leave the player’s camera under their control.
- Original music and sound, included
- Lantern Hour supplies the pub loop, Doorway Breath the encounter sting, with original ambient and celebration sounds. All default music, textures, meshes and effects arrive in the package.
- Your world, your comfort settings
- The host enables Halloween before loading; guests receive the event setting. Personal audio sliders, an apparition toggle, atmosphere strength and reduced motion let each player choose their presentation.
- Wallet and cursor fixes retained
- The combined package retains the recent host-money persistence and F3/F5 cursor-release fixes alongside the existing multiplayer systems.
- Multiplayer menu & character
- Seven tabs organize Play, Worlds, Character, Settings, Imports, Mods and Community. Reduced motion and a standard cursor are available. Approved face, shirt and trouser PNG skins transfer with size and hash checks.
- Managed mods & Head lamp
- Managed installation is applied after exit with backups. Required versions and hashes are checked before joining. The Head lamp 1.0.1 adapter shares light state; the author’s mod is a separate download. Experimental mods are labelled and are not claimed to be synchronized.
- Rivett tuning
- Brake regulators, rev limiter, four race-shock bump/rebound controls and supported tachometer settings follow part identity through installation and removal. Native starting and mechanical rules remain in place.
- Flea-market resale & personal earnings
- Shared rental and listings use individual seller ownership and saved earnings, including offline sellers. Legacy listings with unknown sellers require explicit assignment. Retail purchases and fireworks retain their existing synchronization.
- Four-player transport & bounded work
- The Spacewar membership parser accepts three guests and retains surviving peers. Cached bindings and incremental discovery reduce repeated work. Four-account acceptance and controlled performance measurements remain pending.
- Private Commander
- Website Admins and active Developer accounts can inspect reported sessions, telemetry and moderation outcomes. Guest reports stay separate. Live viewing requires the HTTPS WebSocket relay and a connected reporting agent.
- Rivett construction & handoff
- Mechanical assembly, fasteners, electrical wiring, doors, installed passenger seats and engine state have explicit shared contracts. Every possible build and damage combination is not yet verified.
- Rivett windows & rollover recovery
- Six window frost/scrape values and scrape sounds join the shared glass system. Passenger controller and exit handling were tightened after rollover reports.
- Prepared rally world
- F3 separates resuming a rally world from creating a fresh prepared Rivett copy. Three stages track individual entries, timing, penalties and once-only rewards.
- Shared work & personal pay
- Futufon work, taxi, sewage, kilju and wood jobs have dedicated synchronization. Factory wages are apportioned from validated work rather than multiplied for each player.
- Fuel, repairs & inspection
- PSK pump ownership and metered delivery, Fleetari service requests, inspections and personal banking extend the earlier shared shop and restaurant flows.
- Traffic, train & police
- Train visibility, rolling sound and whistle, road traffic and bound NPC presentation have host-owned streams. Police outcomes remain individual; recent testers confirmed a driver-specific speeding fine.
- Items & equipment
- Magazine deliveries, towing attachments, tractor equipment, passenger item use and the log splitter use scoped synchronization and recovery paths.
- Performance & diagnostics
- Cached seat/driver checks and bounded update work reduce repeated work. Private diagnostics help investigate stalls; a measured overall FPS gain is not claimed.
Version compatibility. This update is 0.9.0+hall.2 / P101. Host and guests need the same complete package. Helper IPC remains 6. The host enables Halloween before loading the world; guests follow that world setting.
Verification scope. Automated synchronization and save checks passed, alongside selected local in-game presentation and cleanup checks. Four separate Steam accounts remain a distinct acceptance step. Short local frame-time comparisons varied between runs and do not establish a general FPS gain.
02 / The plan
One system at a time.
Implemented does not mean fully accepted.
The roadmap follows the current synchronization matrix.

Shared sessions
World transfer, supported transports and explicit ownership are implemented. Long-session recovery remains part of regression testing.

Vehicles, jobs & businesses
Rivett, station transactions, factory work, repairs and inspections now have code coverage; they are no longer future-only plans.
Implemented
Halloween addition
The saved hunt, personal rewards, pub makeover, Teimo outfit and bundled original audio form one optional event. Local visual, lifecycle and regression checks passed.
