Ostranauts Fire in the Hold Update
April 21, 2026 — combat, mining, Ceres, fires, and Steam Deck foundation for 1.0
Fire in the Hold is the April 2026 milestone that rewrote mid-game Ostranauts before version 1.0 landed on Steam 2026-08-03. Blue Bottle Games shipped ship combat, fire and smoke, asteroid mining, Ceres faction conflict, Steam Deck and gamepad support, and Steam Cloud saves — systems the launch build polished rather than replaced. If forum posts or videos predates April 2026, they may describe a peaceful OKLG-only sim that no longer matches AppID 1022980.
This page summarizes what changed, what captains should relearn, and where dedicated guides cover each layer.
Release date and positioning
Dan Fedor announced Fire in the Hold on 2026-04-21 as the combat-and-industry capstone of Early Access — not the final 1.0 stamp, but the mechanical foundation 1.0 stability passes built upon. Marketing copy leaned belter noir: corporate proxy wars, mining explosives that double as weapons, and hull fires that spread through pressurized decks.
Returning captains should read this page, then Version 1.0 Launch for bounty systems, Steam Workshop, filled station maps, and Ceres Affair closure.
Ship combat systems
Fire in the Hold introduced systemic ship-to-ship combat:
- Point defense cannons — ~12–15 km envelope, ~85° arcs, 20mm interceptors
- Mass throwers, coilguns, railguns — 150mm kinetic weapons; railsniping at VCRS ≈ 0
- Missile launchers and Polaris decoys
- Whipple shields and ablative cladding
Combat gear concentrates at Ceres — BCRS Ring Station and BCER Port Mojave — with reputation gates between Galilean Confederacy and CCRE alignments. Full captain workflow: Ship Combat guide and Ceres conflict zone map page.
Post-milestone hotfixes addressed weapon tracking against high crossing velocity targets and sudden hull detonation edge cases — continued into 1.0 week.
Fire and smoke
Hull fires and smoke spread couple combat damage, mining accidents, and atmosphere simulation. Extinguishing fires can restore faction standing when collateral damage angered station security — a patch note captains still cite in 1.0.
Systems reference: Fire and Smoke. Pair with Manage Atmosphere and Life Support Parts when refitting fire lockers.
Asteroid mining
Asteroid clusters become physical mining sites — tether like docking, handheld tools, shaped charges, ore types from iron and olivine through platinum, iridium, palladium, hydrates, and gangue. Sell at BCER and BCRS ports with faction pricing quirks.
Guide: Asteroid Mining. Shared hardware with combat means mining tugs need defense or quiet routes.
Ceres and faction conflict
Ceres became the belt hub for mining income, combat vendors, proxy war story beats, and pirate traffic. Atlantis-named stations expanded as staging hubs. Early Access gray placeholders gave way to content-dense diamonds on the nav map — finalized further in 1.0 station passes (Tharsis Landing, Labyrinth, Voltaire, Jade Rabbit among others).
Map page: Ceres Conflict Zone. Travel prep: Stations and Travel and Fusion Torch Drive.
Steam Deck, gamepad, and Steam Cloud
Quality-of-life for platform reach:
- Steam Deck playable — UI compromises on dense PDA screens
- Gamepad bindings with Options rebinding
- Steam Cloud save sync between PC and handheld
Controls page: Gamepad and Steam Deck. Keyboard remains primary for first-time learning — Keybinds.
What Fire in the Hold did NOT ship
Clarify expectations for historians:
- Bounty hunting — added at 1.0 launch, not Fire in the Hold day one
- Steam Workshop — 1.0 with 40+ mods at announce, not April milestone
- Story conclusion — Ceres Affair closure in 1.0, not April
- Multiplayer — never; single-player only throughout
Relearn checklist for returning captains
If your last session predates April 2026:
- Read this page end to end
- Skim Ship Combat before Ceres undock
- Rerun Getting Started finance and shift reminders
- Update checklists — atmosphere, salvage run
- Walk new Ceres stations on foot before combat sorties
- Read Version 1.0 Launch for bounty and Workshop layers
How this milestone fits the wiki
- Updates hub — future patch tracking
- Guides hub — walkthroughs assuming Fire in the Hold mechanics
- Review — whether combat pacing suits your play style
- Map hub — OKLG home versus Ceres ambition
Official patch text remains Steam news for AppID 1022980 and Blue Bottle Discord announcements. This unofficial wiki translates milestone language into captain priorities: relearn travel risk, respect fire systems, and do not day-one combat with a salvage tub.

Is Fire in the Hold included in Ostranauts 1.0?
Yes. The August 2026 release builds on Fire in the Hold systems with stability, story closure, bounty hunting, Steam Workshop, and filled station maps — see Version 1.0 Launch.
What should I read first after skipping since before combat?
Start with this page, then Ship Combat and Getting Started shift reminders. Do not rush Ceres until life support and flight are boring.
