Subterrain is an indie survival game set on a colonized Mars where players take control of Dr. Albert West, the apparent sole survivor of the underground city MPO. The experience centers on managing a wide array of personal needs while navigating hostile environments filled with mutated threats and scarce resources. Top-down perspective gameplay combines resource scavenging, combat, and base maintenance in a single-player format that emphasizes careful planning over rapid action.
Gameplay
Core systems revolve around tracking hunger, thirst, exhaustion, oxygen levels, and body temperature as Dr. West explores the colony. Injuries such as fractures or blood loss require specific medical attention gathered through scavenging or research. Combat involves both melee strikes and ranged firearms that can be customized with modular attachments for different situations. Enemies start in cocoon forms and evolve into stronger monstrosities if left unchecked, forcing players to address threats before they escalate. Time pressure comes from an infection that spreads across the facility, requiring constant movement between safe zones and generator repairs to stabilize oxygen and temperature controls.
Crafting forms a major loop through collection of junk, creature parts, plants, and ores. These materials feed into 3D printers for armor, weapons, and grenades, while a Bio Combiner produces performance enhancers and specialized gear. Research unlocks upgraded versions of items, including advanced options like custom lightsabers or power armor. Randomly generated sub-levels mix with hand-crafted districts to create varied exploration paths, supported by non-linear story delivery through audio logs and environmental sequences.
Game Modes
Subterrain operates entirely in single-player. Four difficulty settings adjust the intensity of survival demands and enemy behavior: Easy, Normal, Hardcore, and Nightmare. These options scale needs decay rates, injury severity, and overall resource scarcity without altering the fundamental structure of exploration and combat. No separate campaign variants or multiplayer options exist.
Story and Setting
The narrative unfolds in 2050 after humanity establishes MPO as an underground refuge from Mars surface conditions. Dr. West arrives to pursue a cure for his wife's Alzheimer's but faces imprisonment following a lab incident. A year later, with guards gone and the facility in chaos, he awakens to discover the catastrophe that overran the colony. Clues scattered through logs and locations reveal the infection's origins while players restore habitat systems and search for an escape route.
