Sell Lemons World 2 Guide

How to unlock World 2

1. Finish enough of World 1 that the Stargate path is open on your save (Project Stargate portal segment needs Ascensions).
2. Open Teleport and pick Stargate, or walk Installation Stargate from Lemon X.
3. Reach the Select World portal inside the Stargate interior.
4. Choose World 2. You should land near The Center / Oxygen Pump, with stalls selling flavored air instead of lemonade.

What resets and what carries

Resets on World 2 list

• Run cash (TBA) and World 2 buildings start at zero. Click the Oxygen Pump for the first dollars.
• Alien Investors do not follow you. World 2 uses Alien Researchers instead.
• World 1 income tiers and manager progress stay on World 1 until you teleport back.

Carries across worlds list

• Orchard trees, plots, mutations, and Tokens stay permanent across worlds.
• World Energy from the World Reactor (v1.4.0) feeds a shared Global Multiplier, up to ×10 at the Energy bank cap.
• Cosmetic companions stay unlocked; they still do not add cash.
• Cave progress (obby clears / Brave Explorer) and badges survive Inversion.

Oxygen stations list

Build pads unlock in order through Orbital Oxygen Port, Oxygen Forge, then The Horizon. Unlock costs are on each pad.

• Put cash into the newest unlocked station first. Older lines only get topped up when the new one stalls.
• Use Manage for per-station upgrades. Hold the upgrade button when hold-to-buy is available.
• Product Display, kiosk windows, tips, and automated stands are cheap early multipliers off the pump.
• Loyalty Program and Welcome Mat inside Fast O2 are worth buying early if you see them.
• Ice chunks on the Mars terrain are pickups while you hop between domes — not a separate income tier.
• After Forge, clear every income-area button before expecting The Horizon / Inversion path to open cleanly.

Alien Researchers list

• Alien Researchers replace investors. Each one adds +1% cash on World 2 (Robux buys can raise TBA per Researcher %).
• Rebirth at the Alien Researchers UFO near Fast O2 / Joe. The reset clears buildings and cash, then banks the new Researcher count.
• Rebirth prompt colors: red = too early, green = wipe is worth it. Wait for green.
• Claim offline earnings before you rebirth so that cash counts toward the run you cash in.
• Researchers spent on Powers still count toward Evolution thresholds, but stop giving their cash bonus while spent.

World 2 powers list

• World 2 powers include Manage, Run Faster, Stack Upgrade, Remote Buy, Expert Picker, and Jetpack (tier counts vary).
• Remote Buy rebuilds pads from anywhere after a rebirth. Hold-click when hold-to-repeat buys are available.
• Jetpack helps dome hops and the You Peaked exploration badge (highest floating boulder at Oxygen Port).
• Forever Purchase tokens (Robux or from Inversion) can lock pads gold through resets — not Hills, and not Horizon buttons.
• Speed Up Time is a timed boost; use it on active rebirth sessions, not idle AFK.

World 1 Remote Buy unlock math is still on the Remote Buy guide.

Map exploration list

Optional jetpack climbs, black-hole / first Inversion path, flavored-air stalls, and the cave entrance under The Center.

• Jetpack to the highest floating boulder at Oxygen Port for You Peaked.
• Black-hole / Singularity path ties into first Inversion (Spaghettification badge) — exploration, not a cash shortcut.
• Market stalls rotate flavored-air jokes (Vanilla, Mint, Earth, Diet, Free Roam). Flavor labels are not multipliers.
• Cave entrance sits under The Center on a side road — three rising-sand obbies below.

Caves (v1.6.0)

Three rising-sand obbies under The Center. Brave Explorer needs all three clears. Artifact name and effect are on each pickup.

• Entrance: hole on a side road from The Center. Center room plus three rising-sand obbies with time leaderboards.
• Rising sand teleports you to the entrance if you stand in it too long. Flowing sand slows you and blocks jumps; sand waterfalls add heavy gravity.
• Each obby needs three jump-on buttons before the completion room. Brave Explorer needs all three clears — walking in once is not enough.
• Three portfolio artifacts also sit in the caves — name and effect are on each pickup.

Cave obby rewards

Save slots & place saving

Same v1.6.0 drop: replay without wiping old progress, and load into the world you last left.

• Save slots let you start a fresh run without wiping an old save — pick a free slot before a clean World 2 or Halloween grind.
• Place saving returns you to the world you last left (World 1 vs World 2) on the next join.
• World 2 tycoon customization and three new leaderboards ship in the same patch; they do not change oxygen pad order.
• An in-game update log and save indicator show recent patches and when data writes (data still saves on leave).

The Horizon

Late World 2 area after the oxygen stations. Eight tiers of boosts that survive rebirth and gas evolution; wipe on Inversion.

• The Horizon sits at the end of the main tycoon path (behind the elevator toward Oxygen Port). First unlock needs Pilot Panel plus a TBA cost on the pad.
• Eight tiers of buttons: structures, income-source boosts, global boosts, and decorations. Global boosts are ×15 cash; per-source boosts climb by tier.
• Horizon buttons survive Researcher rebirth and gas Evolution — they only wipe on Inversion.
• Buy out every other income-area button before you expect Inversion to open at the Singularity.

Primordial Void and gases

Unlock at 501.2 Quadrillion Researchers, evolve at the Void Altar for ×31.998 income speed per step, and climb Oxygen through Clarity.

• World 2 evolution is the Primordial Void, not the World 1 Purple Portal.
• Portal unlocks at 501.2 Quadrillion Researchers (including Researchers spent on Powers). Pop-ups show as you approach.
• Enter the vortex near Fast O2 / Joe, jump the floating asteroids, and touch the Void Altar to unlock the Evolution menu shortcut.
• Each evolve grants ×31.998 income speed (stacks) and advances the gas (Oxygen → … → Clarity).
• Evolution resets the tycoon, Researchers, and Powers — The Horizon pads stay until Inversion.
• A Robux skip lets you evolve without wiping progress — buy it on the Evolution panel if you want it.
• Rebuild pump → Fast → Warehouse → Center → Gardens with the new gas label. Skip Cutscenes in Settings if the scene slows repeats.

Gas ladder

Inversion

World 2’s top prestige after The Horizon. Pick Inversion Cards, keep Forever / cave / badge progress, wipe everything else on Mars.

• Inversion is World 2’s top prestige (like Ascension on Mars). Finish The Horizon, use the Singularity, and rejoin if the menu does not appear.
• First Inversion plays a cutscene (Spaghettification badge). You get five random Inversion Cards; the same card does not show twice in one draft.
• Pick two cards. A one-time Robux buy adds a third pick for that Inversion only.
• One card is always Forever Purchase while you still have eligible pads. Forever cannot mark Hills or Horizon buttons.
• Inversion resets World 2 tycoon, Researchers, Powers, Evolution (gas), and Horizon. Cave progress, badges, and Robux purchases stay.
• Legendary Singularity Inversion Card unlocks the Singularity companion (cosmetic mini black hole).

Weather

Eight Mars weather phenomena with global cash boosts. Forecast sits bottom-left.

• Bottom-left Weather Forecast shows current and next weather with global cash boosts.
• Run rebirth / evolve sessions during Rain → Eclipse when you are online.
