Cthon

Cthon is a science-fiction first-person shooter set in the 24th century, when humanity has only recently begun expanding into star systems near the Solar System. On a misshapen moon in the Epsilon Eridani system, the Pythos colony was established to mine the planetoid’s resources. Its people have disturbed a powerful evil entity known as Cthon, which lurks within the moon.

You explore an ever-changing labyrinth and fight the dark forces inside, reshaping yourself with cybernetic technology from a long-dead alien civilization. Your goal is to confront the greatest threat to mankind yet encountered.

Explore the labyrinth

Fight through nine sprawling, randomly generated levels; no two games are the same. Permanent death makes each run final. The labyrinth also contains secret areas with rewards and dangers, and multiple difficulty levels let you adjust the challenge.

Build your cybernetic fighter

Choose one of three characters, each specialized for different cybernetic builds. An upgrade system lets you choose which stats to improve and when, with millions of possible combinations. Defensive modifications can strengthen your physical abilities, while offensive ones can increase your firepower and provide new ways to kill your enemies.

Fight and resupply

Battle corrupted humanoids, alien abominations and biomechanical constructs, each with tactical strengths and weaknesses. You can spend nano-tech currency at machines that forge items, replenish resources and expand your cybernetic framework.

A complex, haunting soundtrack accompanies the game’s dark atmosphere.
