"Klei Fest" Introduction and News

Hey Everybody!

I have a bunch of news for you today - We have some new things coming up to announce, a new set of Twitch drops and the introduction of our Klei Advocates program.

Klei Fest is Coming Next Week!

Once a year around this time we have a Klei Publisher sale. Going forward we are also going to focus on making this time a sort of Celebration of Klei Games. During this two week period we will have a burst of content, items, events, sales and interesting things happening.

As an introduction things will be a little less formal this year as we kick things off with a bit of a test run.

All Games: We will begin our Klei Publisher sale next week on June 3rd.

Hot Lava: June 3rd, Players will Race against Lord Sludge in a special course - secure yourself a win an get a special reward. This challenge and reward are only available during Klei Fest!



Griftlands: Griftlands full campaign officially launches as we leave Early Access June 1st on PC and June 4th on PS4, Xbox and Switch.


Oxygen Not Included: The team for ONI has their heads down right now as they work on "Spaced Out!" so we will not have promotional content for you this year, however Oxygen Not Included will be on Sale during the Klei Publisher Sale beginning June 3rd.

Don't Starve Together: We will be celebrating Klei Fest with a new Yearly Limited time event called "Midsummer Cawnival!". Our survivors will be greeted by the enigmatic Corvus Goodfeather, who needs a bit of help preparing the festivities for his crow compatriots. Decorate, try your luck at the Cawnival games, and maybe even win some prizes!



New Twitch Drop Campaign: We will begin a new twitch Drop Campaign for the Leviathan Chest starting June 3rd. Streamers that will have drops available can be found in the spoiler below. Note that this will be the last campaign of this type, further campaigns will be done through our advocates program. See the official forum post.



Klei Advocates Program: We have hired Fourth Floor to run a new Klei Advocates program. This new program will create opportunities for us to grow our relationship with content creators. We have been working with Fourth Floor for quite a while now and this new arrangement will see Fourth Floor working with our most dedicated streamers beginning with the next DST Character refresh at the end of June. More details to follow in the coming weeks.

And that's what I have for you today. See you all next week!

[Spaced Out! Hotfix] - 464102

Hi friends!

We've got a patch for Spaced Out! that enables mutations on Sleet Wheat, Nosh Sprouts, and Gas Grass. It also fixes a few crashes and other bugs. Enjoy, and have a great weekend!

[h2]Changes[/h2]
  • Sleet Wheat and Nosh Sprouts now roll for mutations across their entire crop, rather than not at all
  • Gas Grass is now a normal seed producer for Spaced Out
  • Symbol tinting/scaling works for all plants now. This creates new visual differences for Bountiful, Exuberant, and Juicy Fruits mutations
  • Revised Metallic biome icon
  • Rocket Port building strings updated
  • Updated Simplified Chinese strings

[h2]Fixes[/h2]
  • Saturn Critter Trap no longer says it can mutate its seeds
  • Hooked up missing Saturn Critter Trap Seed artwork
  • Fix crash when toggling compost on mutant seeds
  • Fix a case where multiple rockets launching on separate worlds could emit gasses into the wrong world or not at all
  • Only play the "launch ignition" animation on rockets when taking off, not landing
  • Fix case where rocket ports would appear to be offline even though they were loading or unloading a rocket
  • Worldgen: Fixed border temperature gradient sometimes having its temperatures swapped
  • Worldgen: Extreme temperature borders now have a less extreme temperature in the middle
  • Pause screen now appears above other screens

Spaced Out! - The Peculiar Plants Update


Hello everyone!

Where has the time gone? It's May already and would you believe this is the 6th update we've put out this year!

Since Early Access began, we've expanded on the space gameplay, added a bunch of new asteroids to the cluster map, and created new Spaced Out- and Classic-style starting asteroids. We’ve launched the entire radiation system, including radbolt infrastructure, research reactors, and Beetas. We've put in railguns, revised rocket parts for interplanetary infrastructure, and restored sustainability to the late-game. And now, we're putting radiation into your farms with...

The Peculiar Plants Update for Spaced Out! This Update introduces a whole new layer to farming, and allows you to utilize radiation for the good of your Duplicants’ tummies! There's also a number of radiation related (and unrelated!) tuning and balance changes, and new logistics options with the Meter Valves!

First, Plant Mutations are a brand new feature that integrates radiation with farming gameplay. There are now several strains of mutant seed that crop plants can drop when grown in radiation. Once analyzed at the new Botanical Analyzer, plants grown from these seeds will offer new trade-offs or efficiencies for your farms.

Along with updates to the farming economy, we've also made a number of changes and bug fixes to food preservation. Fridges are more effective at prolonging your food (and don't have so many bugs in them), and a more thorough mastery of temperature and atmosphere is required to fully preserve food.

Newly added Meter Valves have been added to allow sending specific amounts of material down your liquid, gas, and solid piping. Research Reactors' internal physics have also been updated, so you might want to double-check your colony's nuclear safety protocols. Rocket Ports and Launch Pads can be chained together. A lot of artwork has been updated and sound effects have been added.

And of course, we've made many fixes and improvements based on your feedback! We're still focused on improvements and quality of life, so there's never a better time to let us know how this DLC is working for you. Thank you for all your discussions and reports, and keep them coming!

What's New And Improved?

[h2]Features[/h2]
  • New Plant Mutation system allows specialized crop development
    • Exposing plants to radiation causes them to drop mutant seeds
    • Botanical Analyzer building will identify the traits of mutant seeds
    • Mutant crops can be farmed for new tradeoffs and optimizations
  • Added Gas Meter Valve, Liquid Meter Valve, and Conveyor Meter buildings.
  • Updated Codex entries, descriptions and lore
    • New plants
    • Cryotank
    • Radiation biome
  • New artwork for the Rocket Port Loaders

[h2]Changes and Improvements[/h2]
  • Food preservation changes
    • Rottable items now have two stages of cooling: Refrigerated and Deep Freeze
    • Rottable items aren't fully preserved unless they are both in sterile atmosphere AND deep-frozen, because temperature and atmosphere effects now stack
      • Temperature and atmosphere effects have been rebalanced to account for this
      • Refrigerated food now lasts 5x as long instead of 2x
    • Food preservation times were incorrectly reported in the Codex, and were missing their refrigeration value
    • Rottable foods correctly detect if they're in an active fridge or not
    • Refrigerators cool things to 2 degrees celsius instead of 4 degrees, so that they actually get cold enough to be refrigerated. (Note: foods in a powered fridge are always considered refrigerated regardless of temperature.)
    • Foods dropped from a fridge will no longer continue cooling off on the ground
    • "Unrefrigerated Food" notification now jumps to that food when clicked. (Only partially stale unrefrigerated food in storage will trigger the notification.)
  • Errand "offset" fixes
    • Fix exploit where Duplicants can pick up items diagonally through walls if standing on a raised tile
    • Duplicants can access constructions diagonally from a greater number of nearby positions
    • Farm Tiles and Hydroponic Tiles now allow corner access for delivery chores.
  • Added low coolant diagnostic criteria to Research Reactor
  • Research Reactor
    • Fixed issue with inconsistent coolant/reaction mass conduction
    • Enriched Uranium mass target increased 20x
    • Increased coolant/reaction mass conduction scale 5x
    • Meltdown temperature increased to 3000k
    • Added new meltdown animations
    • Fixed issue with temperature meter
    • Increased meltdown projectile mass

  • Small visual changes and added text label to radbolt direction selection panel.
  • Added a new Duplicant animation on the main menu
  • Non-crop plants now also have an ambient radiation limit
  • Swapped Conveyor Chute and Conveyor Receptacle in the tech tree.

[h2]Sound[/h2]
  • Added Mud & Polluted Mud ambiences
  • Added sounds for Mud falling, landing and Duplicant movement on Mud
  • Added sounds for Radbolt Generator and Radbolt Reflector
  • Fixed some instances of two click sounds playing simultaneously.
  • Added missing Lead Suit Locker door closing/opening sounds.
  • Added movement sounds to various radiation locomotion sets.
  • Added movement sounds to the vomiter locomotion set.
  • Added sounds for Radbolt traveling and explosion
  • Added sounds for Duplicants reacting to radiation
  • Added sounds for Railgun rail cleaning.
  • Added Uranium Ore mining and movement sound effects

[h2]Bug Fixes[/h2]
  • Worldgen: Fixed an issue with spawning guaranteed geysers in some Forest Cluster seeds.
  • Worldgen: Improvements to guaranteed POI spawning rules to decrease the amount of worldgen failures.
  • Fixed closing tag for Forest Moonlet string (for translations)
  • Fixed failing to switch worlds after using dev debug
  • Fixed animations rendering outside of the world
  • Plant sorting was broken on the planter box sidescreen, now the crops are consistently ordered
  • Moved uranium materials further in the build materials list
  • Fixed crash when dead Duplicant is hit by a Radbolt
  • Fixed issue where buildings with solid parts like the Solar Panel and Fish Feeder would leave behind a "ghost floor."
  • Fix crash that could occur if trying to load a world whose data no longer exists (i.e. a mod world)
  • Fix some cases where a rocket would not correctly attach to the Rocket Ports on landing or disconnect on takeoff
  • Launchpads now connect to Rocket Ports through each other in chains, so you can reliably have launchpads share ports
  • Fix crash that could occur if a Launchpad was selected when its rocket takes off
  • Rockets would sometimes wipe out each other's conduit endpoints, resulting in e.g. fuel tanks not getting fuelled
  • Add check on the main menu that prevents crashing if the newest save file is corrupted or otherwise problematic
  • Buildings and objects which have been marked "Empty Storage" now save/load the errand properly
  • Minor art revision to the Niobium Geyser
  • Fixed off by one error when calculating Rocket Platform/Rocket position ceilings
  • Wilting Wheezeworts no longer emit radiation if they were wilting on load.
  • Gas and Liquid Shutoff valves now immediately end their flowing animation when a red automation signal is received or no gas/liquid is flowing.
  • Radbolt Generator progress meter hookup. Restored Radbolt animation when more than 1/2 way to launch.
  • Fixed a crash where rockets and pads weren't correctly aware of each other during launch. This won't happen any further, but existing saves may require rebuilding the launchpad under the rocket before the rocket can successfully take off.
  • Fixed a scaling issue with the Arbor Tree where the art was blurry at certain stages of the grow cycle
  • Fixed issue that caused Cluster Style selection screen background to sometimes misalign
  • Fixed rockets disappearing when landing offscreen

[Spaced Out! Hotfix] - 461546

Hi everyone! We're made lots of fixes to worldgen to further prevent temperature leakage between biomes, as well as some POI fixes. Thanks for all your feedback and examples!

[h2]Worldgen[/h2]
  • Marshy Asteroid now always has at least some Jungle.
  • Improved preventing POIs breaking high temperature borders.
  • Fixed an issue where the starting asteroid in Classic Style Terra Cluster generated few or no Oil Reservoirs.
  • Improved Abyssalite border drawing to prevent small amounts of magma appearing on the wrong side of the border.
  • Prevent terrain "features" from drawing over adjacent biomes of a different type.
  • Improved border temperature gradient in extreme temperature cases. It's not perfect yet.
  • Slight improvement to spawning POIs in the magma core of the Marshy Asteroid.
  • Increased water mass on Water Asteroid to prevent significant water receding due to liquid compression.

[h2]Fixes[/h2]
  • Fixed issue that could occur when revealing asteroids with liquid surfaces
  • Rockets are once again able to fly through Rocket Platforms and other rockets - though they cannot idle overlapping with them.

[h2]Other[/h2]
  • Updated Russian translations
