Undertale Multiverse Simulator Links Hub

This hub is the link drawer for Undertale Multiverse Simulator 1.5. It exists because the original place was hacked, old URLs still circulate, and search results mix the live remaster with copies. Bookmark this page. When a friend asks “what is the real game,” send the Roblox URL below, not a screenshot of a Discord embed that can be edited later.

This wiki is unofficial. We are not SlayerRealNotFake, not Toby Fox, and not Roblox. Undertale is Toby Fox’s trademark. The live experience is a fan battleground on Roblox. Use the links here to join the correct file and the correct conversations. Use guides and players when you actually want to play.

Child pages go deeper: Discord links lists invites with labels (community versus creator showcase) and fake-server warnings. Community resources covers unofficial Fandom wikis and YouTube showcasers. This hub stays on the short list you should verify first.

Official Roblox page (the only join link that matters)

Play here: Undertale Multiverse Simulator 1.5 on Roblox.

Confirm before you press Play:

• Place 112050560592995
• Universe 10202515720
• Creator SlayerRealNotFake (user 8026801929)
• Title in the [UPDATE] Undertale Multiverse Simulator 1.5 family
• Free Action / Battlegrounds, 15-player servers, R6 morphs

If any of those strings fail, you are not on the remaster. The identity checklist is expanded on Version 1.5 Remaster. The old place 7915723993 is documented on original game history as a file you should not join.

The Roblox description itself is short: this game is a continuation, it got hacked, after a year it is back; R lowers HP on PC; Z opens the emote wheel; gamepad shift-lock is X. That is the official text. Anything else you read about codes, restores, or “all-ages soon” is community talk until it appears on that page.

Discord

The 1.5 Roblox listing does not pin a single official Discord in its description. Invites still matter because this community historically used Discord for soul restores, event pings, and kit footage. We keep the working URLs on Discord links. Labels there are honest:

• A community / Fandom-linked invite is not the same as a developer announcement channel.
• A creator showcase server (for example a YouTuber’s) is for footage, giveaways, and comments — not patch notes.
• An event invite may go stale the week after a badge ships.

Never join a server whose invite arrived as “free 10 million souls” in a random DM. Fake invites are covered on the Discord page on purpose. If you only need codes, start on the codes hub and treat Discord as a rumor mill until a string works in-game.

Fandom wikis (unofficial, and one is unmaintained)

Two Fandom sites exist:

• Original UMS Fandom wiki — old, unmaintained, still useful as a 1.0 archive. Its own homepage now warns people toward 1.5 and a newer wiki.
• Remastered UMS Fandom wiki — unofficial fan wiki aimed at the continuation. It is not this site and it is not an official developer manual.

Both are fan projects. Attack tables on the old Fandom describe 1.0 kits. Do not spend 1.5 souls from those numbers. How to read them next to YouTube footage is on community resources. When a Fandom page and this wiki disagree on a live price, trust the in-game room, then file the difference mentally as “archive versus remaster.”

This wiki

You are on undertalemultiversesimulator.wiki, an unofficial English-root fan site with localized pages. It is built to answer the searches people actually type after 1.5 came back: which place is real, do souls transfer, how to grind, how to beat Pesti, where Discord went.

Start here depending on the job:

• New on 1.5 — getting started
• Need currency — soul grinding and codes
• Picking a morph — players, starter roster, stronger zone, event kits, tier list
• Named fight — beat Pesti Sans
• Patch context — updates
• Risky executors — scripts (read the warnings; do not paste blindly)
• Calculators and helpers — tools

External links on this hub use visible anchor text. Internal links use trailing slashes. We do not hide a URL as “click here.” If a link dies, that is a wiki bug; tell us rather than fishing a replacement from a YouTube comment from 2025.

Copies, lookalikes, and old bookmarks

After a hack, clones appear. Some reuse the thumbnail. Some reuse the name with “revamp” or “fixed” stuck on the front. Some are the original ID still sitting in someone’s favorites. None of those are a shortcut back to your 1.0 inventory.

Rules of thumb:

• Favorites in the mid thousands and visits in the millions match the live 1.5 listing better than a 200-visit clone.
• Creator name beats thumbnail. If it is not SlayerRealNotFake, leave.
• A scripts page that says “join this place to restore OG” is a red flag, not a tool.
• Keep this hub and the 1.5 remaster notes next to each other. One is the URL. One is the identity card.

How a link earns a slot here

A URL stays on this hub only if we can say what it is in one sentence: official Roblox file, labeled Discord, unofficial Fandom, or this wiki. We do not add random “UMS hub” sites, paid Discord nitro ads, or Trello boards we cannot verify. When an invite dies, the Discord page should say so rather than silently swapping in a new code from a comment section. If you found a better official source — a developer group, a pinned Roblox description Discord — it has to appear on the live Roblox page or a trusted creator channel before we promote it. Until then, the short list above is the whole drawer.
