Quick answer: In Steal an Egg, find Paranoid Pete at Spawn, repair his broken machine, and claim the Signal Decoder. UFO encounters repeat every 30 minutes at :00 and :30. Use the decoder to locate the ship, deliver three eggs carrying the Abducted effect, collect UFO Debris, and return to Pete to trade it for an Alien Mutation consumable. Recent community walkthroughs report a 500 Debris trade price, a 15% application chance, and a ×2.5 income multiplier for Abducted. Check the live trade window because game values can change.
There is an important update distinction: Update 11 — UFO Invasion launched on November 2, 2026. The full Alien Biome is a separate Update 12 scheduled for November 7, 2026, at 11 a.m. Eastern Time (16:00 UTC). The biome is not the same thing as the UFO event already running.
What the UFO Invasion update adds
Update 11 adds Paranoid Pete’s repair quest, the Signal Decoder, recurring UFO encounters, a three-egg delivery objective, UFO Debris, and an Alien Mutation consumable that can apply the Abducted effect. The event is a repeatable activity rather than a one-time launch mission.
- Quest starter: Paranoid Pete at Spawn.
- Quest reward: Signal Decoder.
- UFO timing: every half hour, at :00 and :30.
- Delivery requirement: three eggs with the Abducted effect.
- Event currency: UFO Debris.
- Mutation item: Alien Mutation consumable, traded from Pete.
How to repair Paranoid Pete’s machine
Go to Spawn and find Paranoid Pete beside his radar booth. Talk to him to begin the quest, then interact with the broken machine next to him. It opens the Alien Sensor Tracker pipe puzzle. Your goal is to connect the Power input to the Tracker output so the route lights up.
Community walkthroughs describe this common starting-board solution. Tile layouts can differ, so treat the live board as the final authority:
- Count rows from the top and columns from the left; column 1 is beside Power.
- Turn the bend in row 2, column 1 so it connects from Power and points upward.
- Turn row 1, column 1 so the path comes down and then turns right.
- Rotate the three straight pieces in row 1, columns 2–4, to run horizontally.
- Turn row 1, column 5 so the path enters from the left and exits downward.
- Rotate the straight piece in row 2, column 5 vertically.
- The cross-shaped piece in row 3, column 5 can connect in any orientation.
- Turn row 4, column 5 so the route turns right into the Tracker.
- Check that the connected pipes glow green, then claim the Signal Decoder from Pete.
If your board is shuffled differently, do not blindly copy coordinates. Trace a continuous pipe route from Power to Tracker and follow the quest prompt.
When does the UFO appear?
The reported recurring schedule is every 30 minutes: at the top and halfway point of each hour (:00 and :30). A UFO can appear in different parts of the map, so do not wait at one fixed biome or assume it always lands beside Spawn. Equip or use the Signal Decoder and follow its signal indicator to locate the encounter.
Plan around the next half-hour mark, but stay ready for the event banner and the decoder’s live direction. Community trackers report that a UFO may remain for only a short window, so move promptly after it appears. Server timing and event behavior can change after updates.
How to deliver the three Abducted eggs
Once you locate the UFO, the stated objective is to deliver three eggs that already have the Abducted effect. Three ordinary eggs do not satisfy the requirement. The update overview does not fully explain how every egg acquires that effect or which rarities qualify, so check the current objective and avoid spending valuable eggs based on an unverified assumption.
When the third qualifying egg is accepted, the UFO encounter completes and drops UFO Debris. Collect the dropped currency before leaving. The precise amount can vary, and a guaranteed payout for every run has not been established by the update announcement.
How to get Alien Mutation Crystals and Abducted
Return to Paranoid Pete with your UFO Debris and open his trade interface. The reward is referred to as an Alien Mutation or Alien Mutation consumable in current community walkthroughs. Some guides call it a crystal. These names describe the trade item; Abducted is the mutation effect you are trying to apply.
| Detail | Current reported value |
|---|---|
| Trade cost | 500 UFO Debris per Alien Mutation |
| Application chance | 15% |
| Abducted income multiplier | ×2.5 |
| UFO schedule | :00 and :30 each hour |
Verification note: the update overview confirms the reward loop but does not publish every price or stat. The 500 Debris cost, 15% chance, and ×2.5 multiplier come from recent community gameplay guides and may change. Read the trade panel before spending currency, and do not assume one consumable guarantees the mutation.
Rare UFO and the Alien Staff: what is known
Some community walkthroughs report a special Rare UFO that can pull players aboard. Those reports describe a yellow note near the control desk with a four-digit vault clue and an Alien Staff reward. One walkthrough records the code 4827, but this is not a developer-confirmed permanent code. If you enter a Rare UFO, inspect the note in your own session before using the keypad. Spawn odds, access conditions, and loot can change; do not treat a rare encounter as guaranteed every cycle.
Update 12: the full Alien Biome is a separate release
The full Alien Biome is scheduled for Saturday, November 7, 2026, at 11 a.m. ET (16:00 UTC). That is separate from the November 2 UFO Invasion event. As of this guide’s November 4 check, details such as the final egg pool, pet list, rarity rates, income values, and biome access requirements should not be guessed before release or a reliable update note confirms them.
Common mistakes to avoid
- Waiting at Spawn for the UFO instead of using the Signal Decoder to locate it.
- Delivering three regular eggs instead of three eggs with the Abducted effect.
- Confusing the Abducted effect on a delivery egg with the Alien Mutation consumable bought afterward.
- Assuming the machine puzzle has identical tile orientations on every server.
- Treating the Rare UFO vault code or spawn odds as guaranteed official information.
- Confusing Update 11’s UFO event with Update 12’s full Alien Biome.
