Nuclear Neighbors BETA BETA Updates

Nuclear Neighbors BETA is a public BETA. Building Adventure has not posted a long, dated patch blog that we can quote. What we do have are Roblox badge creation timestamps and a few platform fields on the experience page. This hub is the map. The inferred note-by-note page is the BETA changelog.

Read every date here as evidence of a system existing by that day, not as a studio press release. Badges can be added after a feature, or in the same session a feature ships. We label that gap instead of pretending we sat in their team chat.

The experience is online multiplayer with 20 players per server. Patches hit everyone in the bunker at once. There is no single-player-only branch to hide on.

How we date this BETA

• Badge created — the timestamp Roblox stores on each badge. This is the spine of the changelog.
• Universe created — 3 August 2026. That is when the place record exists, not a “1.0 launch.” The title remains BETA.
• Universe updated — 6 September 2026 as of our last check. That is a Roblox “Updated” stamp. It does not name the patch. We will not invent “Update 4” around it.
• Group shout — the Building Adventure shout was empty when we looked. When it is not empty, it belongs here.

We do not scrape random Discord screenshots. No official Discord URL is published on the group. See the links hub.

Timeline at a glance

15 August 2026 — ending badge

Alien Saviors (“Get the Alien Saviors ending”) is the earliest badge on the universe. Inference: an ending path existed in the public BETA by this date. Hatman as a named badge comes later (26 August). Do not collapse those two dates into one drop.

22 August 2026 — survival day badges

A full day track landed: First day jitters (day 1), Home sick (day 5), Getting cozy (day 10), True survivor (day 50), Help me (day 100). Inference: the day counter and the long-run survival goal were official enough to badge. Day 1 has been awarded on a huge slice of accounts; day 100 has not. That spread is the difficulty curve, not a missing patch.

26 August 2026 — encounter, side-loop, and wheel badges

This is the large wave: Hatman, toilet creature, police rats (BUSTED), fridge beans, Skeleto (GET AWAY), vampire friend, mutated beans, Child of Radiation, cricket pile (Awkward..), cryptid hunt, Spin the wheel!, Time thief, Cryo Chad, and Stinky. Inference: random encounters, a reward wheel, a cryo pod upgrade path, and several joke / hygiene challenges were in the build by this evening. Some badges in this wave still have zero awards; that is a player-skill wall, not proof the content was removed.

28 August 2026 — Hard and Deadly

Skin and Bones and Pure Radiation badge Hard mode (10 and 50 days). THE END IS NEAR and One Above All badge Deadly mode (5 and 50 days). Inference: Hard and Deadly were live as selectable difficulties by this date. One Above All sitting at zero awards means the 50-day Deadly gate is still a frontier, not a tutorial.

What this hub is for

Use it as a table of contents, not as a rumor mill.

• Full inferred notes: BETA changelog.
• Reward loops that are live without codes: wheel and badges.
• Empty promo table: codes hub.
• First-hour plan after a patch: getting started.
• Why not to “patch” the client yourself: scripts hub.

When a real patch note appears on the experience description or the group, this hub will quote it in a new dated section and keep the badge-inferred history underneath so older dates stay labeled as inference.

How to notice a new drop in a 20-player server

You will often feel a patch before you read one. A new HUD button, a new neighbor, or a new difficulty toggle is a clue. Then check two places: the Roblox badge list (a new badge almost always means the studio wants the system tracked) and this hub. If chat claims “codes just dropped,” confirm on the codes hub before you trust a string.

Bookmark this hub, then open the BETA changelog whenever a new badge appears on the Roblox experience page. Badge birthdays are currently the only dated trail we trust.
