Subterrain: Mines of Titan is a turn-based survival RPG set on the surface of Titan, a moon of Mars. After a meteorite crashed into this celestial body, tons of rare minerals burst onto its surface. The mining company TESS decides to send personnel to the site of the disaster to organize a resource-extracting colony. After a while, communication with the base is lost and a rescue mission is sent there. Rescuers have so far been able to find only one survivor, who woke up after cryosleep. This is the main character who will have to find out what happened at the station.

In Subterrain: Mines of Titan, a lot of attention is paid to character survival with the following key parameters:

• Nutrition – the character must constantly look for food and water to quench hunger and thirst.
• Health – After battles, injuries such as broken bones and blood loss need to be treated.
• Crafting is the search for materials to improve your equipment and weapons.
• Energy and Oxygen – Controlling these resources is vital when exploring mines.

Movement and battles in the game take place alternately in a step-by-step mode. You can use melee or ranged weapons, including grenades. There is a possible upgrade to increase the damage done. Nanomachines will allow you to use special abilities that offer new tactics in fights. It is possible to trade with other survivors, as well as communicate with them to find out what really happened in the colony. You can also help the colonists in setting up their base by obtaining resources for them.
