Survival Mechanics

Added sprint, train collision hazard, and oxygen/Nexus details
Survival in Railborn requires managing several systems simultaneously. Beyond the challenge of expanding the train, players must keep themselves alive by sourcing and maintaining food, water, and breathable air. The planet's environment actively works against the player at every step.
The primary threats to player survival are:
Starvation: food must be gathered or grown to maintain health.
Dehydration: water must be collected and managed on the train.
Suffocation: the outside air is toxic, making extended time off the train dangerous without protection.
Environmental hazards: the planet itself presents obstacles and dangers across the track network.
Players gather food from the world around them in the early game. As the train grows, dedicated farming railcars can be constructed to grow vegetables and other crops. Small vegetable plots can be established early, providing a more reliable food source than pure scavenging. Rare plants found across the dying planet can also be cultivated in greenhouse cars, preserving plant life from extinction while helping to sustain the crew.
Water cannot be assumed to be available. Players must actively capture it from sources found along the track network and route it through the train's water distribution system. Managing water supply is one of the core ongoing responsibilities.
The atmosphere outside the train is hazardous to human life. Players venturing off the train to gather resources or explore face suffocation risk. Managing air supply is an important consideration when planning off-train excursions.
The train's systems depend on power, and power must be actively managed and distributed. As new railcars and systems are added, the power network must be expanded to support them. Failure to maintain power affects the train's ability to function and move.
Rescuing and cultivating rare plants from the dying alien world is part of the survival loop. These plants can be grown in greenhouse railcars, providing food and helping to recreate small functional biomes on the train itself.
Players have a sprint to cover ground quickly, which draws on the suit's power. The developers describe it as a way to reach safety, for instance when a suit is running low on power and the player is verging on death. Managing when to sprint is part of survival away from the train.
The moving train itself is a hazard. Jumping onto the train from the side while it is in motion is safe, but being struck head-on (t-boned) by the train is fatal. In cooperative play this means players can run over their teammates with the train, so coordination near a moving train matters. See Co-Op.
Because the outside air is toxic, the player's breathable oxygen limits how long excursions off the train can last. The Nexus can be expanded to grant bonus oxygen, extending safe time outside. Growing biomes and harvesting motes from plants also feeds the longer-term food and restoration loop.
