Surviving Mars: In-Dome Buildings Pack is a strategy simulation expansion for the PC colony builder Surviving Mars. It adds eight new structures that fit inside domes to improve housing variety and community services for Martian settlers.
Gameplay
The core loop centers on establishing a self-sustaining outpost on Mars. Players begin with unmanned drones and rovers to scan terrain, extract resources such as metals and water, and construct essential infrastructure. Once basic power, oxygen, and water systems are in place, rockets deliver the first colonists who require protected living spaces inside domes.
Resource chains demand constant attention because buildings consume maintenance materials and colonists have shifting needs for comfort, health, and sanity. Research unlocks improved production methods and new structures while disasters like dust storms test the colony's resilience. The In-Dome Buildings Pack integrates directly into this system by providing specialized options that expand what can be built within each dome's limited space.
Smart Apartments offer higher-density housing with amenities comparable to premium residences. The Seniors Residence caters specifically to older colonists, while the Large Nursery supports more children in a single facility. Service buildings such as the compact Medical Post and Security Post allow finer distribution of care and order without occupying large footprints, and the Hospital adds capacity plus an upgrade that lowers staffing requirements.
Game Modes
Survival Mode serves as the primary experience where the colony must endure indefinitely with colonists as the sole failure condition. Players balance growth against external threats and internal needs across an open-ended timeline measured in sols.
Challenge Mode presents predetermined scenarios with fixed sponsors, locations, and objectives that must be met within strict time limits. Completing these within tighter windows earns a perfected rating, after which the map continues as a standard colony.
Creative Mode reduces resource costs and removes many survival pressures, shifting focus toward large-scale construction and experimentation with building layouts and dome designs.
Dome Life and Community Services
Colonists live and work inside domes that shield them from the Martian environment. Housing choices influence morale and population growth, while service buildings address daily requirements for medical attention, security, education, and entertainment. The added TV Studio Workshop and School Spire extend options for media production and advanced learning, helping maintain higher comfort levels as the settlement expands.
These structures slot into existing dome categories for habitats and dome services, allowing players to customize layouts without altering core mechanics. Larger options like the Hospital free up space elsewhere by consolidating care functions, and the spire-style School Spire provides vertical efficiency in crowded domes.
Is It Worth Playing?
The base game maintains Mostly Positive reception across tens of thousands of reviews, reflecting steady interest in its resource and colonist management systems. The In-Dome Buildings Pack enhances dome customization for players who enjoy refining residential and service districts. It ships with the Relaunched edition released in 2025, which includes quality-of-life updates and additional content such as a dynamic political system.
Those who value detailed city-building within survival constraints will find the pack useful for creating more varied and efficient colonies. It suits single-player sessions focused on long-term planning rather than fast-paced action, and the included structures remain relevant in both standard and creative playstyles.
