Clean the WORLD Underground Chapter 3

Chapter 3 is the Underground area called out on the live Roblox description for Clean the WORLD! by Bring Back Old Robloxians (place 105767799784652). The same blurb still lists Outer Space as Chapter 4 “forthcoming.” This page is the status sheet for Underground only. It is not a walkthrough of a map that players cannot enter yet. Universe metadata showed the experience last updated on 26 August 2026 with Prestige-era copy still in the description—more upgrades, bug fixes, balancing, F2P access to former Robux upgrades—not a Chapter 3 launch note.

If a thumbnail promises “FULL UNDERGROUND GUIDE,” demand footage from this place ID. We will not sketch fake tunnels.

What official text actually says

The published description, checked against the live Games API, still reads in this order:

1. Prestige update: goodbye pay-to-win; former Robux upgrades obtainable for free-to-play players.
2. More upgrades, bug fixes, balancing.
3. Underground area coming next update — labeled Chapter 3.
4. Outer space forthcoming — labeled Chapter 4.

“Coming next update” is a studio teaser, not a calendar. It can sit in the description for weeks while Prestige and SEA loops remain the playable content. Treat Underground as named and unreleased until the place description or in-game UI says you can enter it.

Cross-check the wider chapter list on the Roadmap and shipped economy notes on Prestige Update.

How to know it shipped

Use boring, reproducible checks:

• The Roblox description drops “coming next” language or adds a present-tense Underground sentence.
• A new badge appears that is not on the current official set (WELCOME, Cenozoic Era, Mythological Creatures, Miocene Epoch Era, Mesozoic Era, Turtles Don’t Eat Plastics Silly, TIME TRAVELER, I’m Above The World).
• I’m Above The World currently has zero awards and the official description “It’s time to clean the outer space!” — that points at Chapter 4, not Underground. Do not treat that badge as proof Chapter 3 is live.
• You can walk into a subterranean area on place 105767799784652 and screenshot the place ID in the same session.

Until those happen, keep grinding current eras. Sitting idle “for Underground” is a worse plan than finishing horses, gorillas, dinosaurs, and SEA as mapped on Progression.

What we still mark unknown

• Release date and timezone.
• Whether entry requires a rebirth (TIME TRAVELER’s official text is “REBIRTH FOR THE FIRST TIME”—see How to Prestige).
• Whether gum, shredders, or seagulls carry below ground.
• New helper families, Game Passes, or a server-size change (live max players remains 7).
• Whether progress wipes. Assume nothing; wait for tooltips.

Prep that is still useful

1. Confirm you are on the correct place via Verify Place ID.
2. Unlock helper rungs that already exist: horses (Cenozoic copy), gorillas (Miocene copy), dinosaurs (Mesozoic copy), SEA via the turtle badge copy “You unlocked the SEA!” — details on Eras and Badges.
3. Prefer permanent upgrades over cosmetics so a new layer has power to spend. Readiness notes: Upgrade Readiness.
4. Re-time pace after any Prestige shop change with the Cleanup Calculator.
5. Optional store extras stay optional; names only on Game Passes.
6. Ignore washer-game “new map” patch notes from Chaseroony.

Relationship to SEA and Outer Space

SEA is playable coastal content (seagulls, shredder, more ocean upgrades) even while Underground is pending. Outer Space is Chapter 4 and is separately teased; the unreleased I’m Above The World badge even uses outer-space flavor text. Dedicated sheet: Outer Space Chapter 4. Do not skip SEA because Chapter 3 is advertised. Advertised is not shipped.

Communications hygiene

Discord screenshots without a verifiable official invite are rumors. The Community Links page tracks how little official social surface we can vouch for. When Underground actually opens, this page should gain a checked date, entry steps, and links to any new guide sections—not a speculative loot table the night before.
