Steal An Egg Alien Biome launches on Saturday, November 7, 2026 at 4pm GMT in the UK. That’s 11am EST in New York and 8am PST in Los Angeles. Those times come from the developer’s Roblox event listing, which puts the start at 16:00 UTC.
You’ve probably already seen Paranoid Pete and the UFOs that arrived earlier this week. They’re part of Update 11, which you can play now. The November 7 Update 12 brings the Alien Biome itself. Here’s the worldwide launch schedule, what the announcement says and what to do before it opens.
Steal An Egg Alien Biome release date and time worldwide
The official Steal An Egg Alien Biome event begins at 16:00 UTC on November 7. The UK is on GMT and the US has switched to standard time, which is why some older countdowns using BST or EDT may show the wrong hour. The update starts at the same moment for everyone, even where it’s already Sunday.
| Region | Alien Biome launch |
|---|---|
| United Kingdom | Saturday, November 7 at 4pm GMT |
| United States Eastern | Saturday, November 7 at 11am EST |
| United States Pacific | Saturday, November 7 at 8am PST |
| Central Europe | Saturday, November 7 at 5pm CET |
| India | Saturday, November 7 at 9:30pm IST |
| Japan | Sunday, November 8 at 1am JST |
| Sydney, Australia | Sunday, November 8 at 3am AEDT |
Roblox lists the event until Saturday, November 14 at 7pm GMT. That’s when the event card ends. It doesn’t necessarily mean the playable biome will be removed that day; the developer hasn’t announced an expiry date for the actual area.
Is the Steal An Egg Alien Biome out yet?
No. On Friday, November 6, the Alien Biome is still scheduled for tomorrow. The Roblox card says “THE NEWEST BIOME IS HERE!”, but that’s promotional wording on a future event. Check the date and time on the listing rather than the headline alone.
Make sure you’re opening the original Steal An Egg on Roblox, made by the group and Collect Rare Pets. Games with similar names are easy to mix up, and this update isn’t for Break and Steal an Egg or Steal a Brainrot.
What’s confirmed for Steal An Egg Alien Biome Update 12?
The developer has announced the new Alien Biome and tied it to Pete’s UFO storyline. In the event description, Pete’s radar detects stronger signals, and strange UFO sightings are becoming more frequent. That’s the official build-up to the November 7 release.
There isn’t an official list of new eggs or pets yet, and the announcement doesn’t give an entrance location, Speed requirement, boss or reward shop. Those details will have to be checked when the update opens. A precise Speed number or supposedly complete Alien Biome pet list circulating today isn’t supported by the announcement.
How is Steal An Egg Alien Biome different from UFO Invasion?
UFO Invasion went live on November 2 as Update 11. Talk to Paranoid Pete at Spawn, repair his machine to get the Signal Decoder, then use it to find UFOs at :00 and :30 each hour. Deliver three eggs with the Abducted effect to earn UFO Debris. You can trade that with Pete for Alien Mutation crystals. Rare UFOs can also lead to the Alien Vault and Alien Staff.
Steal An Egg Alien Biome is the next release, not another name for those existing UFO sightings. Completing Pete’s quest could be a useful way to spend today, but the developer hasn’t said you must have the Decoder or UFO Debris to enter the new area on November 7.
What to do before the Steal An Egg Alien Biome opens
If you want to play before the biome opens, start with the current UFO Invasion. Fix Pete’s machine, get comfortable using the Signal Decoder and learn where the existing biomes are. You can also carry on training Speed and improving your base as normal. Just don’t assume any particular Speed total will unlock the Alien Biome: no requirement has been announced.
When your region’s launch time arrives, open Steal An Egg through its official Roblox page and check the game’s update instructions. The event listing doesn’t yet explain where the new biome’s entrance will be. You won’t need a separate download or an unofficial script to receive a normal Roblox game update.
Steal An Egg Alien Biome questions answered
What time does it open in the UK? Saturday, November 7 at 4pm GMT. In Japan and Sydney, the same instant is early Sunday, November 8.
Is the UFO Invasion the Alien Biome? No. Update 11’s UFO encounters are already playable. Update 12’s new biome has a separate November 7 event listing.
Do you need the Signal Decoder to enter? Pete gives you the Decoder for his existing UFO quest. No compulsory Decoder requirement for the new biome has been announced.
Does the biome end November 14? Roblox’s event listing ends that day at 7pm GMT, but that alone doesn’t prove the playable biome is temporary.
So if you’re planning to play on Saturday, the Steal An Egg Alien Biome release is set for 4pm GMT on November 7. The event runs until November 14 on Roblox’s calendar, and the new area’s exact layout, eggs and entry rules will become clear once it’s playable.
