Slime Rancher 2 is the second game in Monomi Park's Slime Rancher series. It entered early access on 22 September 2022 for Steam, the Epic Games Store, and Xbox Series X|S; and for PlayStation 5 on 7 June 2024. The full version was released on 23 September 2025.
A while after the events of the first game, Beatrix Lebeau receives a letter from an unknown sender telling her about Rainbow Island. She sets sail there, and discovers that it already has a slime conservatory waiting for her.
The game introduces several new kinds of slimes. Item Crafting is now available from the start, and Bea can harvest materials used for inventions directly from the overworld without having to build extractors first. Gordos now block your access to portals instead of holding keys.
This game contains examples of:
- Amazing Technicolor World: The grass on Rainbow Island comes in every colour of the rainbow; in Rainbow Fields, it appears iridescent.
- Animal Motifs: Most of the new slimes are based on animals. Cotton slimes are rabbits; angler slimes are anglerfish; batty slimes are bats; ringtail slimes are raccoons and tanukis; and flutter slimes are butterflies. The yolky slime isn't based on a whole animal, but rather a fried chicken's egg.
- Antepiece: Upon popping the Pink Gordo in Rainbow Fields, it will reveal a geyser underneath, acting as a safe introduction to the mechanic. These geysers start appearing more frequently in the Ember Valley, the location that popping the Pink Gordo unlocks.
- Anti-Frustration Features:
- Chickens will continue to breed no matter how many are in a coop, making it easier to feed carnivorous slimes.
- You can now upgrade your vacpack to have extra tanks, which makes carrying around a lot of foods, plorts, or materials at once less tedious.
- Another vacpack upgrade makes it so when you're knocked out, you don't lose the entire contents of your vacpack and get to keep at least one unit of each item.
- You now have the option to sleep until the next night as well as for a flat six hours instead of just until 6am the next morning, allowing you to skip to a convenient time easier.
- Gordos now all require 30 food to pop (with favorites still counting as two) instead of 50.
- Incinerators and ponds can now be upgraded with plort collectors, which eliminates the problem of accidentally vaccuming your Fire or Puddle Slimes while collecting their plorts.
- Art Evolution: The user interface now uses flat pastel colours and a thicker, rounded font (in stark contrast to the original's black Open Sans on white backgrounds), and the Slimepedia's artwork has less lighting and shading.
- Awesome, but Impractical: Linked Cannons. Their description states that they can "efficiently transport items across distances", but that distance isn't very large, and only one item can be loaded at a time. You're better off just using your Vac-Pack to transport items.
- Bag of Spilling: Beatrix brings no items and only 250 Newbucks with her to Rainbow Island. Even her Vacpack upgrades are somehow rolled back.
- Bioluminescence Is Cool: There are flowers all over the islands that glow at night, and the aptly-named Angler Slimes have glowing orbs like anglerfish.
- Cave Behind the Falls: There's a well-hidden one in Ember Valley, which contains the entrance to Powderfall Bluffs.
- Chuck Cunningham Syndrome: The game does away with emails, effectively removing Casey from the story.
- Collision Damage: Occurs when touching Rock Slimes, Crystal Slimes, and Fire Slimes (unless extinguished with a shot of water).
- Contrasting Sequel Setting: The first game's ranch was located in the Dry Reef, a desert dominated by yellow and orange hues. This game's ranch is a glass-dome conservatory in the predominantly blue and green Rainbow Fields. More broadly, while the first game's world mainly consisted of barren, rocky areas (even the Moss Blanket used to be barren, according to Hobson's messages), Rainbow Island is more lush and covered in grass.
- Eldritch Location: The Grey Labyrinth is full of floating rocks, rooms that are Bigger on the Inside, items so unstable that they disappear after a few minutes, plants made of metal, rainbow-coloured distortions in the air that are painful to touch, and more. According to Gigi, it was built to contain and research an entity called the Prismacore, whose influence alters chemistry and physics.
- Equipment Upgrade: Using the fabricator, the player can upgrade their Vac-Pac to increase their maximum health and energy, the efficency of sprinting and using the jetpack, and the size of each inventory slot, among other things.
- Excuse Plot: Beatrice is called to Rainbow Island by a mysterious letter on a boat. The actual story is still in the background, like the first game.
- Expansion Pack World: This game adds Rainbow Island to the Far, Far Range.
- Flunky Boss: The unstable Prismacore, while Gigi tries to purify it, causes the emergence of Tarr Growths that transmute Slimes into more Tarr. Washing away these growths with the Harmonizer-protected water (and the slime-powered hydro shower, which is the only way to turn the second phase, the Giant Tarr Barrier, vulnerable) is how you "damage" the Prismacore into stability.
- Hard Light: Powderfall Bluffs is full of plants made of auroras. At night, aurora paths appear around the mountains that are solid enough to walk on.
- Item Crafting: Slime Science has changed the most of all the mechanics from the first game. It's now available from the start. Instead of building extractors, you can now gather resources directly from nodes. Instead of buying blueprints, you can find them in treasure pods or receive them from NPCs, but all gadgets cost money to build.
- Lost World: Powderfall Bluffs split off from the mainland a long time ago, and was frozen under the Slime Sea like a living snowglobe until it resurfaced due to volcanic activity in Ember Valley. As a result, it contains creatures thought to be long-extinct, such as saber slimes.
- Mix-and-Match Critters: Sea Hens are chicken-shaped seagulls.
- Non-Indicative Name: Rainbow Island is an archipelago.
- Oxymoronic Being: The Slimepedia calls the pomegranite a "living paradox" because it's a plant that only grows in darkness. Despite this, they can be found outside in the green section of Ember Valley, and can be grown in garden plots outside of the Den without issue.
- Player Nudge: After catching a Yolky Slime, BOb will contact you with the message "YOlkkY… .. / yoLkYY + cchIKkNEnS ==== chIkkY chikkY CHiky CcHiikyy ChIKKYYY ChIkYy cHiIky". This actively hints at the fact that, instead of putting them in a corral like any other slime, you're supposed to put Yolky Slimes in an occupied chicken coop.
- Shout-Out: Yolky Slime’s radiant form changes the yolk from yellow to green.
- Slippy-Slidey Ice World: Powderfall Bluffs was frozen in ice for a long, long time, so it's covered in snow, glaciers, and solid auroras. However, there's also a volcanic area with palm trees. It's also the only place in the game where it snows.
- Story Breadcrumbs: There are drones all over the islands which relay messages from a previous explorer's travels. Mochi's third story dialogue implies that these drones are one of her future/speculative journal designs that are impossible with present technology, and her fourth story dialogue has her give Beatrix the blueprints to how she would access any archival data inside them - which works.
- Suddenly Speaking: The conversations with Gigi are the only time in both games that the player is given any sort of dialog choices. There's also a mid-game conversation with Thora where she asks Beatrix why she didn't use the device at the edge of the Glass Desert to go on another grand adventure, which Beatrix inaudibly answers by saying it was broken.
- Terrestrial Sea Life: The Angler Slimes used to live deep in the Slime Sea, but their Slimepedia entry speculates that they came to the surface to eat Sea Hens. Anglers are usually found in coastal areas where sponges and corals grow on land.
- Thematic Sequel Logo Change: The "2" in the logo is multicoloured, referencing the setting of Rainbow Island.
- Trademark Favorite Food: Returning Slimes maintain their previous favorites, and the only new Slimes thus far to avert this trope are Ringtail Slimesnote , Yolky Slimesnote , and Shadow Slimesnote . As before, feeding Slimes their favorite food will double their plort production.
- Cotton Slimes: Water Lettuce
- Angler Slimes: Sea Hens, to the point where the Slimepedia claims they evolved to walk on land just to eat them.
- Batty Slimes: Pomegranites
- Flutter Slimes: Moondew Nectar; unlike the others, this is the only thing they'll eat.
- Saber Slimesnote : Thundercluck Hens
- Twin Slimes: Polaricherries
- Sloomber Slimes: Candied Hens, which they dreamt into existence.
- Hyper Slimes: Turbo Taters
- Version-Exclusive Content: The 0.5 update reintroduced slime toys and added four new ones, each exclusive to a different platform: Glo Glo Foxifur for Steam, Glo Glo Froggo for Xbox Series, Glo Glo Drakey for the Epic Games Store, and Glo Glo Penguino for PS5.
- Water-Geyser Volley: In the Ember Valley (and later the Grey Labyrinth), geysers can be found that periodically erupt and send anything caught in their streams flying. The player can use these to their advantage to gain more height than they could with the jetpack alone.
- Weather Gameplay Mechanic: Rainbow Island has several weather conditions with multiple levels of severity. Rain destroys tarr slimes and can progress into thunderstorms and then lightning strikes, which damage the player. Wind pushes the player, slimes, and items around and can progress into cyclones, which spawn dervish slimes. Pollen can progress into vine tangle, which spawns tangle slimes. Slimefall causes slimes to fall from the sky. Snow, which is exclusive to Powderfall Bluffs, causes piles of snowballs to appear on the ground.
- Weird Weather: As well as regular weather conditions such as rain and snow, Rainbow Island rarely experiences slimefall, where slimes fall from the sky en masse.
- What Happened to the Mouse?: Your previous ranch is seemingly abandoned after Beatrix travels to Rainbow Island.
