The latest public Build a Base RNG description promotes the Tsunami Update. At the 2026-08-05 checkpoint, Roblox states that this is an hourly event where players can fight new sea enemies and get new weapons. The same description confirms that bases fight offline and repeats the Roll → Build → Defend loop.
That short description is not a full patch note. It does not identify the entrance, define how “hourly” is calculated, list sea enemies or weapons, give drop rates, explain rewards, or state an end date. This tracker preserves the official words, separates them from community leads, and records the earlier Bosses promotion as history rather than blending two versions together.
Current update at a glance
Tsunami is the promoted update
The current Roblox API and experience page use Tsunami wording. This is the safest answer to “what is the latest update?” on 2026-08-05.
The event is described as hourly
The description uses “hourly event.” It does not say whether that means on the clock, once per server hour, or another schedule rule.
Sea enemies and new weapons are advertised
Those families are confirmed. Individual names, stats, odds, and permanent availability are not supplied in the public text.
Entrance and rewards can vary by build
Read the event panel in a current server before planning a route or treating a recent video as a complete guide.
What to check when the event appears
Join the official Slungpy Games experience and note whether the current server displays a Tsunami countdown, banner, portal, button, or map change. Record the exact wording instead of assuming that “hourly” means the top of every real-world hour. If the event is missing, rejoin a current server once before deciding it has ended.
On the first attempt, keep the commitment small. Determine whether the event uses your existing base, a separate loadout, or a temporary arena. Observe where sea enemies enter, whether they follow the normal lane, and which layer fails first. Do not rebuild every placement from a video before you know that its server version and inventory match yours.
After a reward, open the relevant item panel and record the displayed name, type, source text, rarity, and any visible odds. New weapons belong in the canonical Weapons index. A title such as “Tsunami gun” is a discovery label, not enough to establish an entity or its statistics.
Player-impact map
Use the update as a checklist across the site instead of duplicating facts in several articles:
- Items: confirm each new weapon name and whether it is event-only before adding it to the Item Index.
- Layouts: compare the normal baseline with the event route in Wave Layouts, especially if sea enemies change pressure or approach.
- Progression: track any new currency, Index entry, Skill, or upgrade separately in the Progression hub.
- Bosses: confirm whether the earlier Boss Waves and relic crafting remain available under the current build before using Bosses.
- Codes: an update name does not prove a code. The Codes hub remains a separate no-verified-code checkpoint.
This one-owner rule prevents a weapon from having conflicting stats on an event page, item page, tier list, and update log. Updates describe what changed; the relevant system page owns the durable instructions.

2026-08-04 - Roblox records the current universe update timestamp
Type: Official platform record
The public Games API records the universe as updated at 2026-08-04T15:01:07Z. This timestamp supports the transition to the current Tsunami description, but it is not a player-facing patch number.
- Use the timestamp to date this snapshot, not to infer an exact rollout minute for every server.
- Older servers or search caches can retain previous wording.
- Recheck the official page when an event guide and live interface disagree.

2026-07-29 - Bosses promotion preserved as recent history
Type: Dated official-search snapshot
An earlier official Roblox description snapshot promoted bosses with custom attacks, relic rewards, and crafting stronger objects. Current community guides still describe the boss → relic → craft loop, but the live public description has since switched to Tsunami.
- Treat the loop as a recent documented system, not the current headline.
- Verify that Boss Waves and crafting interfaces are present in the live server before farming.
- Do not infer boss names, wave numbers, attacks, drops, recipes, or current availability from the old summary.

2026-05-31 - Experience creation recorded by Roblox
Type: Official platform history
Roblox records the universe as created on 2026-05-31. This provides identity and chronology, not a public release changelog. Early community videos and guides can describe older balancing or menus even when they use the correct Place ID.
- Match the creator and IDs before reusing an older tutorial.
- Prefer current interface text for costs, odds, and availability.
- Keep historical descriptions dated so they are not mistaken for the latest patch.

How to compare an old server with a current server
Capture the experience title, update panel, and visible event state in the first server. Leave normally, join again, and repeat the same observations. A difference proves that server state matters; it does not by itself prove which state is permanent. The official current description is the public baseline, while the live menu decides what you can play in that session.
Do not compare two runs after also changing layout, Skills, and items. Keep the base fixed when testing event availability or a new enemy. If a newly obtained weapon is involved, test it against the same wave and preserve the old placement so the result can be reversed.
Latest-update FAQ
What is the latest Build a Base RNG update?
The Tsunami Update is the current official public theme at the 2026-08-05 checkpoint.
Does the Tsunami event happen exactly on the hour?
The official wording says “hourly event,” but the schedule rule is not published. Use the live countdown or announcement rather than assuming a clock boundary.
What are the new weapons?
The official description confirms new weapons as a family but does not name them. Recent video-title leads remain outside the verified index until their in-game names and sources are checked.
Are bosses removed?
No removal is asserted. Bosses, custom attacks, relics, and crafting were in a recent official description snapshot; their current availability needs a live menu check because the public headline changed.
Where are full patch notes?
No creator-owned complete written patch note was verified for this checkpoint. This page therefore records only the official snapshot and carefully labeled history.
