Secret Key Route
Follow this simple guide to summon the UFO, grab the golden key, and open up the ultimate secret zones in the game.
You cannot get this key alone—it requires teamwork or using an alt account. Go to the center leaderboard area and find the Help Station pod. You need to give away a big chunk of your cash ($10 Billion+) to fund another player's base.
The moment your donation goes through, the sky turns dark red and an alien alarm goes off. Look up! A massive glowing UFO will spawn right above the map and drop a green tractor beam onto the plaza.
Step directly into the green beam. Don't jump, just let it float your character up into the bottom hatch of the spaceship. Inside this secret cockpit, the golden UFO Key will be floating right in front of the alien pilot seat. Touch it to grab it and unlock your badge!
Take your UFO Key and run over to the rocky mountains at the edge of the map. Use the key on the sci-fi scanner door. This permanently opens up the hidden Space Zone, the biggest secret area where you can buy end-game LemonX setups.
Finding these hidden areas and getting the UFO Key is only half the battle. If you are a hardcore sweat player aiming for the legendary 0.0% Purity Badge, the Space Zone is where the real grind begins.
Inside this locked zone, you must combine both secrets: use your Sewer Key to extract raw essence from LemonX, and then input the secret code found inside the UFO cockpit into the final Space levers. Doing this correctly triggers the ultimate Ascension sequence!
Once your centillion flow starts multiplying, stop guessing your reset timings. Advance straight to our Rebirth & Evolution Strategy Terminal to track the community-recognized 350% sweet spot and execute the perfect prestige speedrun!
