Originally published in 1997 by Biohazard Games and recently revived with Blue Planet: Recontact, Blue Planet is widely considered a pioneering and successful example of ‘hard’ eco-science fiction in the tabletop RPG space. The game is set in 2199 on Poseidon, an alien waterworld that humanity has fled to following a devastating, 70-year ecological collapse on Earth known as ‘the Blight’. But instead of treating Poseidon as a sanctuary to preserve, the arrival of massive Earth-based corporations has triggered a destructive ‘colonial’ gold rush. The corporations rush to strip-mine a rare ore found deep in the ocean floor that holds the key to human genetic modification and longevity.
The central conflict in Blue Planet is between two competing relationships with the biosphere. Megacorporations, also called Incorporate States, view Poseidon as an untapped trove of raw materials with no clearly defined claims of ownership. Because they represent a dying, desperate Earth, their timeline is short-sighted and they use heavy industrial dredging, seismic blasting, and chemical processing to extract the ore, viewing the resulting dead zones as acceptable externalities. In contrast, the “natives”, i.e. descendants of the first, abandoned colony ship who adapted to a low-tech, traditional maritime lifestyle, and genetically modified cetaceans like dolphins, orcas, and whales understand that Poseidon’s biosphere is a fragile, interconnected system. They live within the limits of this ecosystem and view themselves as parts of rather than removed from the ‘food chain’. Thus, the narrative setup is clearly reminiscent e.g. of the Avatar film franchise and the Na’vi as a fictional ‘noble savage’ archetype.
One of the game’s most evocative themes is making modified cetaceans such as orcas and bottlenose dolphins playable, mechanically fleshed-out characters. By shifting the player’s perspective to a non-human, aquatic species, the game invites players to reassess their own anthropocentrism and rethink more-than-human co-existence from a different perspective. A cetacean character does not navigate the world primarily through concepts like sight or ownership but they experience the ocean through biosonar and acoustics. This means that, for them, corporate industrial activities like deep-sea mining or active naval sonar installations can constitute violent, physically painful acoustic assaults that can disorient, deafen or even kill them.
The game features a Global Ecology Organization, a UN-like body tasked with protecting the planet’s environment while also managing human resettlement. Instead of rendering this regulatory institution as purely ‘heroic’, Blue Planet presents them as a deeply compromised, bureaucratic state power. The organization must constantly negotiate with the powerful Incorporate States, often greenlighting destructive operations in exchange for political concessions, which directly reflects the complex, frustrating reality of real-world environmental policy.
A strength of the game is the sourcebooks for the fantastical but grounded setting (like Natural Selection), which were written with direct input from marine biologists and read like field guides. They detail real-world oceanographic principles, food webs, marine taxonomies, and weather patterns (including fictional phenomena like globe-spanning “hypercyclones”). This makes the environment feel reactive and internally consistent. Another interesting point is the moral ambiguity of direct intervention. Ecoterrorist factions (like the Abyssal Liberation Front) are presented in a nuanced way. The game asks tough questions like whether sabotaging a deep-sea drilling rig can be considered moral if the resulting oil/chemical spill destroys a fragile reef? Moreover, the game explicitly aims to deconstruct the “frontier” myth inherent in a lot of sci-fi settings. It reframes the ‘untamed wilderness’ as a place that is already occupied by the Natives and cetaceans, directly challenging colonial assumptions of ownership through exploitation.
As a corresponding downside, because the worldbuilding is so dense, especially new players of Blue Planet occasionally feel overwhelmed by the amount of marine biology lore, making it difficult for game masters to translate abstract the ecological systems into engaging session-to-session gameplay. On a related note, while the setting is strongly ecologically influenced, the core rules (especially in earlier editions) have relied on traditional combat and skill-check mechanics. There are detailed rules for weapon damage, sub piloting, and cyberware, but fewer mechanics that actively model things like local biodiversity loss, carbon buildup, or systemic feedback loops. The system simulates a conflict over the environment, rather than the environment itself. Moreover, some play groups may experience incongruities between the hard-hitting neo-colonial eco-drama and more ‘pulpy’ narrative tropes reminiscent of 1990s sci-fi like a character impersonating a genetically modified, cybernetically enhanced killer whale wielding a torpedo launcher. Still, the campaigns can offer thought-provoking and nuanced choices that are easily connectable to real-world experiences. For example, in one scenario a corporate patron hires the player characters to locate and harvest a rare deep-sea sponge that contains an enzyme key to treating a terrestrial disease. Doing so, however, requires dredging a thermal vent ecosystem protected by local Native clans. The players must weigh saving human lives on Earth against the local collapse of Poseidon’s unique habitats. In another scenario, players control a pod of modified cetaceans that must map out and sabotage a massive underwater installation deployed by an Incorporate state. They cannot just ‘attack’ the installation but have to navigate changing deep-sea currents, evade predatory alien life, and use their own acoustic skills to disrupt the corporate equipment without causing a catastrophic structural failure.
