[Game Update] - 581979

Release Date: 11/16/23

Update Information:


Hey friends,  

Welcome to the Packed Snacks Update! 

This is ONI's 50th update—we can hardly believe it! Whether you've been choking down mush bars with us since the first one or joined in somewhere along the way, thank you for being here. 

We're celebrating with a new germ-themed story trait, new buildings for storage, food preservation and critter happiness, a sandbox story trait placement tool, expanded critter moods and new cosmetic skins (aka blueprints). These can all be used in both the base game and Spaced Out! DLC. 

We also fixed some bugs, and made a new ONI short! Check that out here.

Grow A Bot 
An abandoned lab full of decommissioned machinery offers an unexpected new use for Zombie Spores that really puts the "ew" in "renewable energy." Once the musty old equipment is up and running again, the colony can use it to build and grow the necessary components for a mechanical alternative to Duplicant labor. That means fewer Duplicants being sent into hazardous work environments!

Food Dehydrator and Rehydrator
The new Dehydrator building is designed to drain all of the moisture out of foods prepared on the Gas Range. Dried foods aren't edible, but they are conveniently non-perishable and don't need to be refrigerated.

When it's time to eat, just send the dried food through the new Rehydrator building to restore its original texture...and most of its flavor.

Creature Comforts
Critter moods have been revised and expanded. The new Miserable state is for extra-glum critters, and results in Glum levels of metabolism plus zero egg-laying. Critters who are not Happy, Glum or Miserable will feel Satisfied—these will have default metabolism and fertility. 
Only Happy critters get a fertility boost. 

We've also added new Critter Condo and Water Fort buildings to boost critter happiness, and worked on some long-overdue bug fixes and changes to Pacus that might affect existing ranches. 

Other Cool Stuff 

  • New design for messages on the Main Menu screen.
  • Nearly 50 new blueprints added to the Supply Closet. 
  • New Storage Tile.
  • New sandbox tool for adding story traits to existing saves.
  • Added a Rocket Port Extension for Spaced Out! DLC.
  • Added a search function to more sidescreens.

A new story trait! A new sandbox story trait placement tool! New blueprints! More nuanced Critter moods! New critter buildings! A new Storage Tile! And so much more. 

If your mods are breaking or you need a little extra time before switching over, you can opt in to the temporary, unsupported Previous Update branch.

Fifty updates later, and we're still loving every moment of this astronomical adventure. 

If you have bug reports or feedback, let us know! We're so glad you're on this ride with us—the ONI universe wouldn't be the same without you.
