World of Slime Demo Guide
Windows Steam preview: what is in, what never transfers, and how not to invent the December client.
The World of Slime public demo opened on Steam on 26 August 2026 as a Windows PC preview (app 4793900), attached to the full game (app 4671450). Mac and mobile wait for December 2026. This guide says what the demo actually contains, what GameChosun said about nicknames, and what this wiki will not invent. For the installer itself, use download the demo. For first-hour capture, use getting started.
What the demo includes
You get the first major area, on the order of thirty species, field capture with Cubes, synthesis, fishing, a village hub, slime riding, and online play with friends including PvP from 1v1 to 3v3. TEAM42 presents it as a feedback preview, not a save to import. GameChosun reported you can stake a nickname ahead of official service. Progress, Slimepedia, and recipes still do not carry.
Steam and the official site agree on the loop: Cubes in the field, a village table for synthesis, fishing as a third recruit path, NPCs who change which field you can reach, and riding (water and sleds) so feet are not the whole map. Official PvP in the design runs from 1v1 through 3v3. The PvP guide is the combat notebook. Powerful slimes deeper in the field can be hunts or allies — powerful slimes.
Windows only, and that matters
The official site is clear: this preview is Windows-only. If friends are on Mac or a phone, they cannot join this build. Point them at mobile for November pre-registration. Cross-play between PC and mobile is the stated December design, not a mixed session with this Windows demo. DualSense and Camera Comfort are Steam flags for PC pads — accessibility. There is no Deck Verified badge in the public dumps this wiki checked.
Everyone who wants to sit in the same session needs the Windows demo installed. There is no “one owner, four guests without Steam” trick in any TEAM42 post. Invite through Steam after they install app 4793900.
Capture, synthesis, fishing
Cubes, not “orbs.” Throw after the stun window. A high-rank Cube does not rescue a throw during an attack animation. Low-rank Cubes fill early meadow pages. Keep a head Cube for a species you have not logged. The capture guide is the long timing version.
Synthesis is live: two partners, a new species, no spoiler sheet (see Dev Notes Vol.1). Log recipes even though the save dies — your memory is what you take to December. Fishing is one of the three official recruit paths. Village NPCs still open map — quests. Ride to places feet cannot — exploration.
What does not carry
Nothing you write in the Slimepedia, no leftover Cubes, no synthesis recipes, no partner bond imports into the December client unless a later Steam News post says otherwise. Treat the demo as a booth you can break. Spend high-rank Cubes to learn timing. Try a silly 3v3. Release a slime you dislike. 26 August is not day zero of a live account. It is day zero of the habit.
The nickname is the social exception GameChosun highlighted. Align Discord Explorer with the in-game string so friends search one name. Wishlist app 4671450 anyway.
What the demo does not include
No real-money shop. No iOS or Android client. No extra continents as a dated fact. Treat “seventy extra species,” ranked seasons, and “endgame raids” as unofficial until patch notes exist. The roadmap holds PlayX4, 26 August, G-STAR, November pre-reg, December PC plus mobile. The codes hub is empty: TEAM42 has not published a redemption UI.
Steam lists about eighteen interface languages on the demo store. This wiki is English, French, German, and Spanish. Pick Korean or Japanese in Steam properties if you need them here.
How to spend the hours
Two to four hours if you actually explore: forest, water, snow, and whatever your partner opens. A one-hour rush skips the book. Learn Cube timing, one fusion, one rider, one 3v3 callout. Then close the client. Write species, weather, clock, and Cube rank on paper. That list outlives the save.
Minimum store specs are Windows 10, Intel Core i5, 8 GB RAM, GeForce GTX 960, 20 GB free. Recommended specs are still blank. If the client will not start, verify files on app 4793900.
December 2026 is still the live service. This Windows demo is the handshake.
Frequently Asked Questions
Quick answers to the most common questions about the game.
Does demo progress carry over to the full game?
No. TEAM42 presents the demo as a standalone preview. Slimepedia, Cubes, recipes, and bonds will need to be rebuilt in December 2026 unless a later Steam News post says otherwise.
Can I play the demo with friends who do not own it?
No. Friends need the Windows Steam demo (app 4793900) installed. Mac and phones cannot join this preview. Cross-play with mobile is the December design.
Will there be more demo updates before launch?
TEAM42 has not announced extra demo patches. Follow Steam News and the updates hub. The dated calendar sits on the roadmap.
Does the demo have microtransactions?
The demo is a preview without a real-money shop. The full game is free-to-play with no gacha; cosmetics and convenience are the stated live-service purchases.
