Calling all armchair terraformers and logistics lovers! If you enjoyed transforming barren celestial bodies into thriving, green havens, it is time to recalibrate your strategy.
Developer Gaddy Games has officially announced that Plan B: Terraform is expanding! Mark your calendars for September 23, 2026, when the relaxing sci-fi planetary simulation releases its first paid DLC, Worlds of Fire and Water, alongside a massive, game-changing Free Content Update.
Whether you want to battle burning lava or navigate endless oceans, humanity’s future is back in your hands.
Two Opposing Planets, Endless New Strategy
Following its successful 1.0 full launch, Plan B: Terraform is taking its tranquil base-building and logistics mechanics to extreme new limits. Priced at just $5, the Worlds of Fire and Water DLC introduces two polar-opposite biomes that demand entirely new survival strategies.
1. The Fire World
This unforgiving, high-temperature landscape is riddled with active volcanoes, boiling geysers, and relentless heat.
- No Natural Minerals: Forget standard mining—you’ll need to wait for lava to cool down into basalt to extract essential resources.
- Cooling Down the Planet: Utilise new specialised tools, construct atmospheric neutralisation plants, and deploy orbital solar shade satellites to block out the harsh sun.
- Water Scarcity: Water is extremely rare at first, relying heavily on localised geysers until you can literally launch rockets to drag icy comets down into the atmosphere!
2. The Water World
If you prefer endless ocean horizons, the Water World will test your spatial management and marine terraforming skills.
- Islands & Expansion: You begin on tiny clusters of land. To expand, you must freeze the planet to grow polar ice caps and lower global sea levels, build dams, or alter the terrain directly to reclaim dry land.
- Deep Sea Mining: Extract minerals directly from the mineral-rich ocean floor using seabed filters.
- Ecosystem Management: Mineral pollution threatens local marine life. You’ll need to clean up polluted zones so sea plants and plankton can thrive, which in turn produce oxygen and sustain the oceanic food chain.
A Giant Free Content Update for All Players!
Even if you stick with the base game, Gaddy Games is dropping a huge collection of new mechanics and quality-of-life additions for everyone on September 23:
- Brand-New Tech Tree: Replacing the old level system, giving you a clearer, more rewarding path to planetary engineering.
- New Logistics Vehicles: Command early-game small ships to cross water bodies and late-game airships to transport massive quantities of cargo across huge distances.
- New Structures & Upgrades: Deploy floating depots, water farms for extra food production, and long-range drone extractors. Upgrades now let you permanently increase storage capacities and boost transport speeds.
- Dynamic Weather & Environments: Experience dynamic polar ice caps, drifting snow, and sea currents that carry marine life around your globe.
Get Ready to Terraform
With its calm atmospheric soundtrack, satisfying hexagonal grid layouts, and deep supply-chain logistics, Plan B: Terraform continues to be one of the most rewarding planetary simulators on PC. The combination of high-stakes planetary engineering and stress-free gameplay makes this upcoming expansion a must-play.
