Sculpt new planetary homes for humanity across two challenging worlds in this chill sci-fi simulation
[September 23, 2026] – Gaddy Games is excited to announce that the Worlds of Fire and Water DLC for calming sci-fi simulation game Plan B: Terraform is available now for $4.99, with a 15% launch discount for its first seven days. Arriving alongside the DLC is a free content update for the base game, which is normally $15.99 and is 30% off as part of a Steam Daily Deal.
The Worlds of Fire and Water DLC introduces two planets with vastly different challenges. The Fire World is plagued by extreme temperatures, a lack of minerals, and constant eruptions, requiring new tools to cool and terraform the planet. Meanwhile, the Water World is almost entirely covered by water, with only small islands available for construction. As temperatures fall, ice caps grow and water levels drop, revealing new land to develop. Each planet presents its own challenges as players work to make these polar opposites livable.
Free Content Update Features:
- A new Tech Tree, replacing the old level system
- Upgrades: one-time upgrades for the container capacity of trucks, trains, and drones, or to make your depots float on water, plus repeatable upgrades to increase vehicle and drone speed as well as extraction efficiency
- New vehicles: early-game small ships and late-game airships
- Dynamic polar ice caps and snow
- Sea plants and plankton that follow water currents
- Water farms to produce additional food
- Rockets to launch shades and mirror satellites, and bring back ice comets
- Greenhouse gas neutralization plants
- Long-range drone extractors
- Seabed extractors
The Worlds of Fire and Water DLC and free content update are available now for Plan B: Terraform on PC via Steam. Return to the planet and begin sculpting humanity’s next home across two radically different worlds.
