Planet Crafter DLC Guide: Planet Humble and Toxicity (2026)

Finished terraforming the main game and want more? The two Planet Crafter DLC worlds, Planet Humble and Toxicity, give you completely new planets to work on. Neither needs your main-game progress, and both can be played as a fresh start.

This guide covers what each Planet Crafter DLC contains, what it costs, how co-op ownership works and how you get there.

🌍 Planet Humble: a compact fresh start

Planet Humble came out on October 9, 2024. The world is half the size of the main planet and brings its own new biomes plus extra lore about space colonization and megacorps. The question at the center of the story: why has nobody settled this planet?

There are two ways in:

• New save: pick "HUMBLE" as your planet when you start a new game. Good for a focused restart without baggage.
• Interplanetary system: once you've terraformed Planet Prime, you can travel there directly.

According to the February 2025 patch notes, the last terraformation stage ends at 4 TTi. Back then that covered Prime and Humble, the only two planets in the game. Neither DLC adds achievements: Miju Games deliberately doesn't tie achievements to DLCs, so players without them can still earn every one.

☣️ Toxicity: the poisoned world

Toxicity was released on November 17, 2025. This planet is heavily polluted by past industrial activity. Instead of starting from bare rock like in the main game, you restore it with new tools and machines. It's slightly smaller than Planet Prime and has its own biomes with fungal plant life and traces of human activity. The lore revolves around Sentinel Corp and the Planet Crafter Program: who lived here, and what went wrong?

Access works the same way as with Humble. Start a new save with "TOXICITY" as your planet, or travel there through the interplanetary system.

On Steam the two expansions are rated differently (as of October 15, 2026). Toxicity sits at about 88 % positive ("Very Positive"), Planet Humble at about 75 % ("Mostly Positive"). Both are solid, but the community likes Toxicity a bit more.

🧪 New resources and Toxic Areas

Toxicity adds its own materials on top of all the base resources from Planet Prime: Tungsten, Toxic Goo, Toxic Spores, Toxic water and Pristine mushroom.

The core new mechanic is the Toxic Areas. Some heavily polluted zones are covered in Toxic Goo and show their own toxicity meter on your HUD. If that meter runs out, you take damage until you leave. You clean these areas with a Goo cleaning microchip (Microchip – T1 Goo cleaning and its higher tiers) or with T1 and T2 Toxic goo removal explosives. A further microchip, Microchip - Toxic Areas Informations, shows the cleaning progress of your current zone.

Toxic water comes from the Toxic Water Collector. According to planetcrafter.th.gl, a Detoxification Machine extracts Purified Water from it, which is safe to drink, plus Toxins. Toxicity is also the longest terraforming run in the cluster: the community wiki lists 6.5 TTi as its final mark instead of 4 TTi.

📖 Why the lore is worth it

Both expansions dig deeper into the background story of The Planet Crafter instead of ignoring it. Humble asks why a seemingly suitable planet was never settled, and the answer ties into the bigger story about megacorps and colonization. Toxicity goes further back. Who was here before the ecological disaster, and what part did Sentinel Corp play in the collapse? If you care about the setting, you'll find much more story here than in the main game.

👥 Co-op: only one player needs the Planet Crafter DLC

Handy for groups of friends: for both expansions, the Steam store pages say only one copy of the DLC is required for multiplayer. Everyone still needs the base game. If you play on console, check our crossplay guide first, because PS5, Xbox and PC don't play together.

🗺️ Separate worlds, same core mechanics

Each Planet Crafter DLC brings new planets, biomes and lore, but the basic terraforming loop stays the same. The Ti index, the core values and the blueprint system work exactly as in the main game. If you know our terraformation stages guide, you'll find your way around both new worlds right away.

💰 Prices and bundles

If you don't care about the soundtrack, the Galactic Terraformer Edition is the cheaper pick over the Deluxe Bundle. The single DLC prices in the table are pulled live from Steam. Prices change, so check discounts and bonuses directly in the store you buy from.

If you plan to play both expansions anyway, a bundle is usually cheaper than buying them one by one. A quick price comparison at the time of purchase is still worth it.

🌱 New biomes for a change of scenery

After a full terraforming run on Prime, you know its biome transitions by heart. Planet Humble packs a compact, independent biome mix into half the map size. Toxicity, with fungal plant life and visible remains of past industry, looks nothing like the familiar red desert of the main planet.

🤔 Which Planet Crafter DLC first?

There's no single right answer, but two pointers help:

• Planet Humble suits you if you want a complete but more compact restart. Half the map size means shorter trips and a tighter run.
• Toxicity is the pick if "restore instead of start from zero" sounds appealing. The poisoned starting point feels very different, and at 6.5 TTi it's also the longest stretch in the whole cluster.

💡 Pro tips

• Before buying, check whether a bundle is on sale. It's often cheaper than both DLCs separately.
• For a co-op group, let one person buy the DLC and host. That saves everyone else money.
• Start a fresh save if you want the DLC experience independent of your main-game progress.
• On Toxicity, craft a Goo cleaning microchip early and wear a jetpack. Both speed up cleaning the Toxic Areas a lot.

❓ Frequently asked questions

Does everyone in co-op need the Planet Crafter DLC?
No. According to the Steam store pages, one copy of the DLC is enough for multiplayer. The rest of the group only needs the base game.

Do I have to finish the main game before starting a DLC?
No. You can start a new save with "HUMBLE" or "TOXICITY" as your planet, or travel there through the interplanetary system after fully terraforming the main planet.

How is Toxicity different from the main game?
Instead of untouched wilderness, you start on an industrially poisoned planet and restore it with new tools. The Toxic Areas add their own cleaning mechanic with a toxicity meter on the HUD that the main game doesn't have.

Can I play the DLCs on console?
Yes. The PlayStation Store sells Planet Humble and Toxicity separately and in a Deluxe Edition with the base game, and the Xbox Store has the Deluxe Bundle with the same three parts. More platform details are in our Planet Crafter PS5 guide.

Checked against the official Steam store pages and announcements by Miju Games, the PlayStation Store, the Xbox Store and the planetcrafter.th.gl game database for item and machine names, as of October 2026 (main branch v2.103, Skeo update). The 6.5 TTi mark for Toxicity comes from the community wiki on planet-crafter.fandom.com. Prices and discounts can change.
