How does the UFO event work in Steal an Egg?
The UFO event starts every 30 minutes, and your goal is to locate the UFO, deliver three eggs with the Abducted effect, and collect UFO Debris.
Here’s how to complete the event:
- Wait for the UFO event: The event starts every 30 minutes, at the 00 and 30-minute marks.
- Equip the Signal Decoder: Take out your tracker to begin searching for extraterrestrial signals.
- Locate the UFO: Travel through different biomes and follow the signal strength until it reaches 100%. Once you’ve found the source, the UFO should appear.
- Deliver three eggs: Find three eggs with the Abducted effect and bring them to the UFO.
- Collect UFO Debris: Complete the delivery to receive UFO Debris, which you can exchange for the new Alien Mutation consumable.
How to get abducted by a UFO in Steal an Egg?
During each UFO event, using the Signal Decoder to search for UFO signals gives you a small chance of being abducted and transported to a secret alien spaceship.
Unlike the regular UFO event, the secret area offers a much better opportunity to farm UFO Debris. Once inside, you’ll have to smash the alien capsules scattered throughout the ship to collect debris.

Destroying all the capsules rewards you with far more Alien debris than the regular UFO event
How to open the Alien Vault and get the Alien Staff
While exploring the alien spaceship, you’ll come across a locked Alien Vault containing a new weapon – the Alien Staff.

You can barely see the Alien Staff residing in the Alien Vault
To unlock it, you’ll need to find a four-digit security code hidden somewhere inside the UFO.
Follow these steps:
- Find the UFO control panel: Look around the spaceship for the control console.
- Locate the sticky note: A small sticky note with a four-digit code is on the control panel.
- Enter the code: Head to the Alien Vault and enter the four-digit combination on its console.
- Claim the Alien Staff: Once the vault opens, collect your new weapon!

It’s confirmed: sticky notes are superior Alien technology

Your code might be different; be sure to check the sticky note on the console

Ready to dispense some extraterrestrial justice
NOTE: The code can be different for each player, so check your own sticky note!
UFO event rewards
The amount of UFO Debris you receive depends on which encounter you complete:
| Event 🛸 | UFO Debris |
|---|---|
| Regular UFO event | 1,500–2,000 |
| Rare UFO encounter | 4,000 |
New Abducted mutation in Steal an Egg
Update 11 also introduces the Abducted mutation, which you can obtain by exchanging UFO Debris for Alien Mutation consumables.
After you complete a regular UFO event or return from a rare UFO encounter, bring your collected UFO Debris back to Paranoid Pete to buy the new mutation consumable.

Each Alien Mutation crystal costs 500 UFO Debris and has a 15% chance of successfully applying the Abducted mutation to an egg.
