Undertale Multiverse Simulator Guides Hub

Undertale Multiverse Simulator 1.5 is already live on Roblox. The loop is simple and long: grind souls, buy AU Sans and Papyrus kits from rooms, then fight other players on 15-player Action / Battlegrounds servers. This hub is the map of that loop. Each child guide answers one search, not a generic “read more” dump.

The live file is the continuation after original place 7915723993 was hacked. Souls from that file do not transfer. Confirm the creator is SlayerRealNotFake and that you are on place 112050560592995 before you invest a night of grinding. This wiki is unofficial and is not affiliated with Toby Fox, Roblox, or the developer.

Start here if you just joined

The first-hour 1.5 join order is the day-one walkthrough. It covers joining the remaster instead of the dead original, the white portal left of the lobby that opens the Starter Characters Room, the cheap 0–4,000 soul kits, and where to go once those kits stop carrying PvP. Pair it with the starter roster and the starter tier list so you do not buy a joke kit with your first stack. If Play is blocked, you landed on the wrong ID, or a brand-new account cannot enter, use how to join the live 1.5 place before you open the white portal.

If buttons feel wrong, stop buying and open the PC, mobile, and gamepad bind sheet. R on PC lowers your own HP so orange and blue bone rules can fire. Z opens the emote wheel. Gamepad shiftlock is X. Mobile has an on-screen low-HP control. That page exists because new players treat R as a “phase key,” which it is not.

Souls, rooms, and the 200k wall

Souls are the only real currency. The soul grind pace and 200k breakpoint is the farming route: community timing from SANES 2 (about 24 hours to the first million, then about 20 hours per extra million after the 200k zone), AFK notes, and a list of purchases that stall you. Use the soul unlock tool before you click a pad, then aim for the stronger character zone (left and right rooms, entry around 200,000 souls).

Phases are prices, evolutions are rooms

How phases actually cost souls explains the mechanic people keep asking in chat. A phase is an extra soul-cost entry in the same character room, not a secret key and not the R bind. Worked examples: Epic Sans at 250,000 / 400,000, Toxin Sans at 300,000 / 500,000 / 850,000, Dusttrust Sans at 580,000 / 850,000 / 1,000,000.

Evolution rooms and ACT 3 is the other half. Killer evo and Alpha rooms are dedicated spaces. Players have reported those doors swapping, so you can click Killer and load Alpha. The page also covers Scarlet Tenacity, Swapfell Papyrus Phase 2, Hyper Dust (the Ruins Dust Sans evo), Fatal Error, and Revenge Papyrus ACT 2 into ACT 3 at 2,850,000 souls. The evolutions roster is the name list; the guide is the “how do I get there without wasting the stack” version.

Event fight

The Pesti Sans event fight is the badge-plus-purchase walkthrough. Beat him for the badge, then spend 2,000,000 souls to use the kit. Community clears exist under 1,000,000 souls if you keep range, teleport off the small blasters, and heal on cooldown. The event has been re-added at least once, so treat it as a rotating window, not a permanent lobby boss. Kit notes live on the event roster.

Tools, ranks, and patches around the guides

After a guide, jump to the matching list instead of re-reading the same paragraph. Starter ranks and stronger-zone ranks sit under the tier list hub. Character names and room layout sit under the players hub. Patch context is on the 1.5 remaster notes and the hacked original file. We have not verified a public promo-code list; check codes and how to redeem after patches instead of trusting random chat strings.

Scripts are a separate, high-risk topic. If you still want that lane, read scripts, how to use scripts, and auto-farm notes — this hub will not paste loadstrings. For binds you can keep on a second monitor, use the controls cheatsheet. Community Discord pointers are on wiki Discord and community links.

Read one guide, buy one kit, then come back. 1.5 rewards a short shopping list more than a full-room clear on day one.
