16 mechanics, as Surviving Mars does them

core · 4

logistics & networks

Fluid pipe networks

Water and oxygen travel by pipe from extractors and producers to domes.

logistics & networks

Hauling jobs

Drones within a hub's range carry resources, build, and maintain buildings.

resources & production

Power grid

Generators and batteries feed cable networks to domes and buildings; a dome without power, water, or oxygen cannot sustain colonists.

progression & goals

Tech tree

Research spans physics, engineering, social, biotechnology, and robotics fields.

Building placement

Modding API

An official mod editor with Lua scripting.

agents & behavior

Mood and breakdowns

Unhappy colonists may become Earthsick or rebels.

agents & behavior

Needs decay

Comfort, sanity, health, and morale change with services and events.

agents & behavior

Personality traits

Colonists have traits, flaws, and specializations that suit them to jobs.

environment & ecology

Planetary climate

Green Planet (2019) adds terraforming of atmosphere, temperature, and water.

risk & failure

Random disasters

Dust storms, meteor storms, cold waves, and dust devils.

resources & production

Resource extraction

Metals, rare metals, concrete, and water are extracted; rare metal exports fund imports.

logistics & networks

Service coverage

Drone hubs and dome services serve within a range.

narrative & generation

Triggered event chains

Mysteries run storylines such as plagues, rival corporations, AI revolts, and alien contact.

risk & failure

Wear and breakdown

Buildings need drone maintenance to keep working.

City builders don't tell stories

transcript

Only one game in our catalog lets you place buildings and also runs chains of story events: 77 games do the first, 17 the second.

In Cities: Skylines, a district built all at once grows old all at once. Decades later its residents die in a wave, and the hearses back up. The game treats it as a services problem. Nothing tells you a story about any of them.

The exception is Surviving Mars, which lays authored mysteries like plagues and AI revolts over a colony you lay out yourself. Even there, the mysteries are layered on top of the colony.

land rockets with drones and prefabs -> drones build power, water, and oxygen infrastructure -> build domes and bring colonists from Earth -> colonists' traits, comfort, and sanity drive work and stability -> research and export rare metals for funding -> weather disasters and Mysteries

design notes

Surviving Mars splits construction from population: drones working within range of hubs build and maintain everything, and colonists arrive only after domes have power, water, and oxygen. Colonists carry traits, flaws, and specializations and track morale, comfort, sanity, and health, so dome services decide whether they work, turn Earthsick, or rebel. Mysteries layer authored storylines (plagues, rival corporations, AI revolts, alien contact) on top of disasters such as dust storms, meteors, and cold waves.
