Good fit

Skip it if you…

Saves you a refund
  • Players seeking a relaxed pace may find the constant hunger, thirst, injury, infection, and environmental management demanding

Our take on Subterrain

The store framing leads with a vast Mars open world, but the experience also depends on repeated survival management, resource processing, and procedurally generated sub-levels. That combination makes the game’s scope feel less like a broad sightseeing sandbox and more like a systems-heavy struggle inside a damaged colony.

What is Subterrain?

Subterrain is a single-player science-fiction survival game set in an underground Mars colony.

Dr. West must manage hunger, thirst, exhaustion, oxygen, temperature, injuries, and infection while searching the colony for supplies and clues. Combat includes melee and ranged weapons, modular weapon customization, evolving enemies, and generator defense during invasions. Resources and creature parts can be processed into components, armor, firearms, grenades, upgrades, survival equipment, and performance enhancers. Research produces improved item versions, while the biosphere and mine provide plants and ores for refinement. Exploration combines freely accessible colony districts, randomly generated sub-levels, handcrafted locations, non-linear story material, and repairs to habitat systems.
