Nuclear Neighbors BETA Inferred BETA Changelog

This page is a reconstruction. Building Adventure has not published a numbered patch list for Nuclear Neighbors BETA. Every dated block below comes from Roblox badge created timestamps on universe 10625421552. If a badge exists, the system it names existed by that moment. The feature may have been playable earlier without a badge.

Labeling rule: lines marked Inference are ours. Lines that quote a badge name or description are Roblox data. We do not add “bug fixes,” “balancing,” or “quality of life” unless a badge forces that reading.

The experience is a public BETA on 20-player online servers. Nothing here is a 1.0 release note. For the short map of the same dates, use the updates hub.

15 August 2026 — Alien Saviors

Badge created

• Alien Saviors — “Get the Alien Saviors ending.”

Inference: by 15 August 2026 the public BETA already had at least one named ending. That is the oldest badge on the universe, so it is the first dated content we can pin. About 340 accounts had the badge when we counted, which is rare next to day 1 but not unique.

Not inferred: a Hatman patch on this date. The Hatman badge is 26 August. Do not write “Hatman/Alien drop” as a single 15 August event.

22 August 2026 — survival day track

Badges created (all on 22 August, minutes apart)

• First day jitters — “Survive day 1.” Awarded on a mass scale (about 153,000 accounts in our count).
• Home sick — “Survive day 5.”
• Getting cozy — “Survive day 10.”
• True survivor — “Survive day 50.” Dozens of awards, not thousands.
• Help me — “Survive day 100.” Still a tiny club.

Inference: the day counter, the 1 / 5 / 10 / 50 / 100 gates, and the idea that a run can last a hundred bunker days were official by this morning. The award counts show a steep funnel: most players who join get day 1; almost nobody holds a server long enough for day 100. That matches a 20-player survival BETA where wipes and weird neighbors exist, not a solo story map.

Not inferred: exact day length in real minutes, food tables, or whether days pause when you leave. Badges only prove the numbered gates.

26 August 2026 — encounters, wheel, and side loops

Badges created this afternoon and evening, in roughly this order:

• Cryptid Killer — “Hunt all cryptids.” Zero awards in our count.
• Hatman — “Get taken by Hatman.” About 1,600 awards.
• Bats? nah friend — “Get the vampire friend.”
• Rotten beans — “Slay the mutated beans can.”
• Child of Radiation — “Become a child of radiation.”
• Awkward.. — “Have 10 crickets spawn during the cricket random event.” Zero awards in our count.
• Midnight Snack — “Get 5 beans in a row from the mysterious fridge.”
• BUSTED — “Get busted by the police rats.”
• Toilet troubles — “Get jumpscared by the toilet creature.” Tens of thousands of awards; this one is common.
• GET AWAY — “Survive 5 days without multiplying Skeleto.”
• Spin the wheel! — “Land on a reward!” About 2,540 awards. This is the live free-reward loop while codes stay empty. See rewards.
• Time thief — “Reach day 10 in under 5 minutes.”
• Cryo Chad — “Reach the max upgrade with they cryo pod.” (Description text is Roblox’s, including the wording.)
• Stinky — “Survive 20 days without showering.”

Inference: 26 August is when the studio badged the “weird neighbors” fantasy the experience description already sold: toilet jumpscare, police rats, fridge, Skeleto, Hatman, plus a prize wheel, a cryo pod upgrade cap, a speedrun-style day-10 challenge, and a hygiene dare. Random events (crickets) and a cryptid hunt were also in the build. Zero-award badges are still real; they are just unfinished by the player base, not deleted.

Not inferred: spawn rates, whether Hatman ends the run, or the wheel’s item slices. A badge description is a trigger, not a design document.

28 August 2026 — Hard and Deadly

Badges created

• Skin and Bones — “Survive 10 days in HARD mode.”
• Pure Radiation — “Survive 50 days in HARD mode.”
• THE END IS NEAR — “Survive 5 days in DEADLY mode.”
• One Above All — “Survive 50 days on DEADLY mode.” Zero awards in our count.

Inference: Hard and Deadly existed as selectable modes by 28 August 2026, with their own day gates. Deadly’s 5-day badge has more awards than Hard’s 10-day badge in our snapshot, which may mean people try Deadly, die, and retry — or that 5 days is simply a shorter bar. We will not pick a story. We will say both modes are online, shared 20-player difficulties, not a local-only challenge room.

Not inferred: the exact stat changes inside Hard or Deadly. No badge lists hunger rates, damage, or spawn tables.

What this changelog will not do

• It will not invent a 3 August “launch patch.” The universe was created that day; that is a platform field, not a badge, so it stays on the updates hub as metadata.
• It will not turn the 6 September 2026 “Updated” stamp into a named hotfix. No badge was created that day in our set.
• It will not list promo codes. None are confirmed. Keep using the codes hub.
• It will not document executor “patches.” See the scripts hub.

If you are new after any of these waves, getting started is still the first hour. The changelog tells you when a system became badge-official, not how to live through the first night with 19 other people.

If Building Adventure later posts a real patch note, this page will switch from inferred badge waves to quoted notes. Until that happens, treat every date above as a badge-creation timestamp, not as a confirmed stream of patch text.
