Is the Raise an Anomaly first zone actually called Zone 1?
Not on the official page. This guide names it first zone so beginners have a starting chapter.
Zone 1 route
Clear the starting zone loop until it is boring. Then you are allowed to go farther.
Updated

The Raise an Anomaly first zone is the starting lab and the nearest steal. The official page does not name it Zone 1. This guide uses “first zone” so new players have a chapter one.
If you came here looking for the 16 September New Zone, open the new-zone guide instead. That is a different URL on purpose.
Learn three cameras: your plot, the path out, and the crib with its guardian. Official art of the crib is your landmark. If you cannot find it, you are still in someone else’s hallway.
Servers are 5 players. The first-zone crib may already have a queue. Wait rather than stacking deaths.

Steal, return, hatch, feed, collect. Repeat until cash appears without panic. That lap is the first-zone campaign. There is no boss at the end.
Spend first cash on whatever failed during the lap. Failed return → Speed. Empty plot → wait for hatch. Tiny body → food.
The guardian is the hazard. Other players are traffic. Hunger (empty food) is the silent hazard when you start chaining steals.
Fear tags on the Roblox page are occasional/mild. Jump-scare art does not add a combat HUD.
Leave when one anomaly is fed and paying, food is in stock, and Speed feels comfortable on the starting path. That is the unlock, not a quest checkmark.
The zones wiki page explains why higher zones exist. This guide is only the starting chapter.

You can complete a steal-hatch-feed lap without looking at this page. Then open the new-zone guide or the Speed wiki, not a random codes list.
If the lap still fails, the steal-eggs guide is the remediation, not a gamepass.
FAQ

No. The crib guardian is a steal hazard. Official data lists 0 badges and no boss table.
