Steal An Egg Alien Biome Update (November 2026) Release Time

The Steal An Egg Alien Biome update releases on Saturday, November 7, 2026, at 11:00 AM EST (8:00 AM PST / 16:00 UTC). I checked the official Roblox event listing, the developers’ Update 10.5 and Update 11 posts, and the top-ranking guides, so you only get confirmed facts. Below you’ll find release times for every region, what the UFO Invasion lead-in did, what’s still unannounced, and how I’d prep Speed before launch.

Steal An Egg Alien Biome Update

The official Roblox event card, titled “NEW ALIEN BIOME,” starts on November 7 at 16:00 UTC. The developers’ Update 10.5 group post confirms the same Saturday, and the Update 11 patch notes on the official Discord repeat it: the biome arrives “next Saturday, November 7 at 11 AM EST.”

One detail other guides skip: US clocks went back on November 1, so the UTC time shifted from 15:00 to 16:00 while the American time stayed at 11 AM Eastern. If your old Saturday routine used 15:00 UTC, adjust it.

Alien Biome Release Times Around the World

If you’re in Asia or Oceania, you’ll see the update on Sunday, November 8, your local date.

When Will the Patch Notes Drop?

Don’t panic if the biome looks quiet at 11 AM. Looking at the last five Saturday updates, the developers’ written announcement landed 1 hour 5 minutes to 2 hours 4 minutes after the listed start. I’d expect the full notes roughly one to two hours after launch, so join on time but read the notes before spending anything.

Is the Alien Biome Live Right Now?

No. As I write this on the morning of November 7 (UTC), the biome is still hours away. The UFO Invasion event that started November 2 is a separate lead-in, not the biome itself.

What’s Confirmed About the Alien Biome?

Everything official so far comes from the Roblox event card, the Update 10.5 post, and the Update 11 Discord notes.

The November 14 end time belongs to the event listing. It doesn’t mean the biome leaves the game. The Enchanted Forest stayed after its own event card closed in early October.

UFO Invasion Recap (Update 11)

Since the biome follows this event, here’s what it gave you, based on the Update 11 notes and community walkthroughs:

• Paranoid Pete: He arrived November 2. Fix his machine to get the Signal Decoder.
• UFO spawns: A UFO appears every 30 minutes, at :00 and :30.
• Abducted eggs: Bring three to the UFO and it leaves behind UFO Debris.
• Alien Mutation crystal: Trade the Debris with Pete to buy it. It gives an egg the Abducted Mutation, but only has a 15% success chance.
• Rare UFO: A rarer UFO can appear, and some players have been abducted inside it.

None of this is confirmed as a requirement for the biome. Don’t assume owning the Signal Decoder unlocks anything.

How Much Speed Will You Need?

The developers haven’t published a number. Here’s the Speed ladder from recent biomes:

Timesaver projects 125B to 180B for the Alien Biome, based on the 2.5x to 3.6x jumps between the last few gates. That is an estimate, not an official figure, and earlier jumps were much bigger or smaller depending on the update. Also remember that the sign’s Speed isn’t the Speed you need to run home with a heavy egg. Aim well above the listed gate before farming the best eggs.

How to Prepare Before Launch?

1. Train Speed on your treadmill. Buy the next treadmill tier and the best Trail you can afford, since Trails multiply Speed gains.
2. Save cash. New biomes often add a stronger treadmill tier, and a full wallet lets you buy it immediately.
3. Keep income ahead of Speed. Upgrade your weakest pen slots first so your Speed push doesn’t stall.
4. Update Roblox before 11 AM EST so a pending patch doesn’t cost you launch minutes.
5. Join on time, then read the notes before spending Robux or currency.

How to Join the Alien Biome Update?

1. Open the official Steal An Egg Alien Biome event page on Roblox.
2. Tap Notify Me for a reminder.
3. Launch Steal An Egg at your regional start time.
4. If the content is missing, rejoin a fresh server and check the developers’ group and Discord for announcements.

Common Mistakes to Avoid

• Trusting “Alien Biome codes.” Steal An Egg has no code system, so any code, generator, or script promising alien pets is fake.
• Buying “leaked” pets. I found no developer confirmation of any alien pet name, rarity, or egg. Treat leak videos as unverified.
• Spending before the notes. Wait for the official patch notes before putting Robux into anything.
• Expecting a crowd-free launch. The event card drew over 6 million “going” marks within about a day, so expect busy servers in the first hour.

FAQs

When does the Steal An Egg Alien Biome release?

Saturday, November 7, 2026, at 11:00 AM EST / 8:00 AM PST (16:00 UTC). In India that’s 9:30 PM IST, and in Singapore and the Philippines it’s midnight on November 8.

Is the Alien Biome the same as the UFO Invasion?

No. UFO Invasion (Update 11) started November 2 and is the lead-in. The biome has its own November 7 event listing.

What Speed do I need for the Alien Biome?

It hasn’t been announced. Estimates of 125B to 180B are projections only. Check the gate sign in-game on launch day.

Are there Alien Biome codes in Steal An Egg?

No. The game has no code system, so any code you find is fake.

Will the Alien Biome disappear on November 14?

Nothing says so. November 14 is when the Roblox event listing ends, and the developers haven’t announced the biome as temporary.
