changedPatch Notes:Balance: Small Shield (Overclocked): 'Extended' health reduced (15000->12000) 'Reinforced' health increased (30000->39000) Flak (Overclocked): Reduced shrapnel cloud health (800->400) Reduced shrapnel cloud lifetime (7s->4s) Reasoning: Overclocked Flak were too cost-effective at blocking damage. Ion Beam Emitter: Increased battery capacity (10->16) Reasoning: Overclocked Ion Beams were too difficult to sustain. Thermal Resonance Lance: Reduced turret speed (60->30) Reasoning: Resonance Lance was too effective at staying on target. Disruptor (Overclocked): Reduced drain vs command rooms by 75%. Reasoning: Command rooms could be indefinitely disabled with very few shots. Railgun (Overclocked): Reduced length buff exponent (1.0->0.9) Reasoning: Long overclocked Railguns were too difficult to defend against. Radiator: Heat from radiators will now heat other ships' shields instead of bypassing them. No longer applies heat to nearby friendly ships. Small/Medium Reactors (Overclocked): Removed bonus battery capacity when overclocked. Reasoning: Reduced the amount of time that overclocked reactors can supply power in excess of their generation rate. M.R.T. Nozzle (Overclocked): Now generates a maximum of 1100 heat instead of scaling with thrust. Heat Mechanics: Reduced base damage resistance debuff (-0.9%->-0.6%) Reduced damage resistance debuff exponent (0.75->0.7) Reasoning: Damage increases from heat were too significant at all heat levels.
addedPatch Notes:Built-In Ships: Added 23 new Monolith combat ships: Adjudicatrix, Atlatl, Auxilia, Caestus, Derringer, Equites, Firewall, Flintlock, Gatecrasher, Gladiator, Halligan, Hand Cannon, Katar, Knuckleduster, Landsknecht, Ombudsman, Partisan, Peltarion, Rainmaker, Sai, Stormcaller, Trident, Vice Added 11 new Cabal combat ships: Altair, Asellus Primus, Asellus Secundus, Asellus Tertius, Camelopardalis, Ignis Ardens, Ignis Benedictus, Ignis Immeritus, Ignis Indominus, Saclateni, Taurus Added 1 new Cabal civilian ship: Shepherd Added 16 new Imperium combat ships: Agrippa, Anhinga, Aplomado, Buteo, Charlemagne, Ferruginous, Firewhistle, Galapagos, Groovebill, Hannibal, Jan Zizka, Nightjar, Roseate, Scipio, Woodpecker, Wryneck Added 1 new Imperium station: Large Imperium Trade Station III Added 3 new Fringe combat ships: Blackguard, Long Goodbye, Matchstick Added 4 new House Io combat ships: Amphisbaena, Mars, Raura, Samghata Miscellaneous updates to existing built-in ships.
addedPatch Notes:Career: Added an "Ironman Mode" advanced game option. Enabling this will restrict the player to a single save file, auto-save when exiting the game, and delete the save when all hands are lost. Stations that are under attack (rescue station missions) can no longer repair the player until rescued.
removedPatch Notes:Multiplayer: In Arena games, junk parts will no longer linger after their original ship is destroyed. (This should improve performance.) The game mode filter in Online multiplayer lobbies will no longer display modes not allowed in that lobby.
addedPatch Notes:Ship Painting: Added decals: 'triangle_slanted_double' and 'resource_munition_thermal' The 'shape_poly_8' decal is now properly centered. The 'faction_io' decal now has faint horizontal stripes like the normal Great House Io faction logo.

    • The 'faction_io' decal now has faint horizontal stripes like the normal Great House Io faction logo.

  • User Interface:

    • Translation updates for all supported languages.

  • Graphics:

    • Thermal Resonance Lances now have a different open/close animation depending on the safety toggle.

  • Performance:

    • Upgrade runtime to Microsoft .NET 10. This should improve overall performance by a small amount.

  • Bug Fixes:

    • Various audio issues on Linux/Proton/Steam Deck.

    • Possible fix for multiplayer disconnects that some players have been experiencing. (PLEASE LET US KNOW IF THIS FIXES DISCONNECTS FOR YOU!)

    • Crash when starting an Elimination game with Fog of War enabled.

    • Crash in single-player when detonating an Explosive Charge while also hovering the mouse cursor over another part.

    • Crash in Build & Battle with 3+ players if at least one player has forfeited and a new build phase begins.

    • Crash in some circumstances if an A.I. ship is destroyed while a comms window is open for that ship.

    • Crash when certain unusually-sized text characters are sent via multiplayer chat.

    • Bullets/projectiles that died on the same tick as the game was saved would become alive again when reloading that save file, which could then lead to crashes and other bugs.

    • Placing parts that changed the heat build stats would occasionally cause the game to hang.

    • Rare hang when jumping to certain star systems in Career mode.

    • Explosions that split ships into multiple pieces could cause multiplayer desyncs and inconsistent damage.

    • Pirates attacking stations would sometimes fly to a different station, making the mission difficult/unintuitive to complete.

    • Infinite money exploit by buying resources and then switching the view to another star system before the transfer is complete.

    • Resources stored in trade ships was being forgotten once the trade ship went far enough from the player (went into "stasis").

    • Stations far from the player (in "stasis") could become more full with trade goods than intended, leaving little room for the player to sell resources.

    • On "Imagineer" difficulty, removing all crew quarters would cause the "ALL HANDS LOST" message to appear.

    • Floating resources could sometimes be left behind after construction is finished.

    • Radiator exhaust was colliding with shields as if the shields were full circles. (Sorry bubble shield lovers.)

    • Visual mismatch between weapon beams (Ion Prism and Thermal Lance) and their actual hit location.

    • Build mode wasn't including floating resources inside gas clouds when calculating the number of resources available.

    • In multiplayer Career or Creative games, double-clicking on a star system on the galaxy map would override the player vote.

    • The quick-load hotkey was unintentionally loading the previous saved game after starting a new saved game. (It now does nothing until the game is saved.)

    • Some of the build and blueprint sounds were using the wrong volume slider to control their volume.

    • Multiplayer incompatibility which could be caused if there are any decal files not listed in the whitelist.txt file.

  • Modding:

    • When uploading a mod or ship pack to the Steam Workshop, you can now set the version(s) of Cosmoteer that it is compatible with. Steam will attempt to download the correct version of the item depending on which version of Cosmoteer the player has selected.

    • When uploading new versions of mods or ship collections to the Steam Workshop, it is now possible to change the name, description, and preview image.

    • All part components that reference triggers can now reference named triggers.

    • Added an optional 'BlueprintBuffMultiplier' parameter to buff providers which modifies the blueprint and buff text values.

    • Fixed NetworkTriggerReceivers not connecting to pre-existing triggers.

    • Fixed crash (without an error message) when any rules file contains an invalid inheritance path.

    • Fixed StatusApplication effects ignoring the 'Shields' filter.

    • TileLineScoreValue components now support an optional 'OccludedByShields' parameter.
