Last updated: May 31, 2026
Overview
UFO is a hidden zone in Sell Lemons with a sci-fi alien theme — flying saucers, cosmic energy, and interstellar decorations. It's accessible only after obtaining the UFO Key (found via the Sewer lever puzzle) and the Good Samaritan Badge. The UFO Key is extremely valuable because it doubles your Investor Cash Bonus from 1% to 2% permanently — this is arguably the most impactful key in the entire game. This zone is a key part of the path to Purity Fruit and 100% game completion.
How to Access
You need the UFO Key and the Good Samaritan Badge to enter this area. The UFO Key is obtained through the Sewer Area lever puzzle — solve it to earn both the Good Samaritan Badge and the UFO Key. Both require the Sewer Key first (Cosmic Cash purchase). Typically accessible after Ascend 50-100. Getting the UFO Key is one of the highest-priority goals because it permanently doubles Investor Cash Bonus from 1% to 2%.
Key Locations
Important spots in the UFO Area:
UFO Landing Pad
The main entrance area. The UFO hovers above — the visual centerpiece of the zone. Teleport here after unlocking the area.
Alien Market
Exclusive alien vendors offering unique deals and items. These may include rare upgrades, Cosmic Cash bonuses, and endgame progression items.
Cosmic Vault
A special vault area with endgame rewards. May contain items needed for Purity Fruit progression and 100% completion.
Good Samaritan Shrine
Connected to the Good Samaritan Badge quest. A thematic location that may offer additional rewards or lore.
Tips & Strategy
Get the Good Samaritan Badge before trying to access the UFO zone. Without it, the entrance won't open even with the UFO Key.
UFO is smaller than other zones but packed with valuable content. Don't rush through — examine every corner.
Keep a Cosmic Cash reserve even after buying the UFO Key. The Alien Market may have items worth purchasing.
Alien NPCs in this area may offer enhanced deals compared to surface Aliens. Answer every call.
