About CTHON

Evil Has Awakened



It is the 24th century, and mankind has only recently begun expanding its reach to the star systems nearest our own Solar System.

A dark and terrible secret is buried within a misshapen moon nestled in the massive asteroid belt of the Epsilon Eridani system. Pythos colony was built there ostensibly to exploit the planetoid's mineral resources, but now they've disturbed a kind of evil that lurks beyond the fringes of our comprehension.

Through an ever-changing labyrinth, you will remold yourself into a cybernetic killing machine using the powerful technologies of a long-dead alien civilization. With these new-found weapons, you will pave a path of aberrant corpses toward the greatest threat to mankind ever encountered.

CTHON is an old school science-fiction first-person shooter, where you become a cybernetic weapon against the dark legions of a powerful evil entity - known only as Cthon - who lurks within the planetoid. It is a classic space horror game, inspired by the likes of Doom, System Shock, and Quake.

Features


  • Fight - and die - through nine sprawling randomly generated levels. No two games are ever the same, and permanent death ensures unrelenting tension.
  • Modify yourself with the cybernetic technologies of the ancients. A unique upgrade-powering system allows you to get down to the details of character building, and choose the stats you want, when you want, with millions of permutations. Mod types include defensive upgrades that can increase your physical strengths and offensive upgrades to maximize your firepower and grant new ways to exterminate your adversaries.
  • Slay an extensive array of monstrous creatures, each with intriguing tactical strengths and weaknesses. Battle corrupted humanoids, alien abominations, and biomechanical constructs as you delve ever deeper.
  • Use nano-tech currency to gain a strategic edge - access machines that can forge new items, replenish your resources, and expand your cybernetic framework.
  • Secret areas abound in the labyrinth; scour the levels for them and reap the rewards - and dangers - they may hold.
  • Choose one of three characters, each of them specialized toward different cybernetic builds.
  • Multiple difficulty levels allow you to adjust the nightmare world to your tastes.
  • A complex, haunting soundtrack complements the dark and oppressive atmosphere.

✦ AI summary

Cthon is an atmospheric retro FPS roguelike with strong aesthetic appeal, praised for its moody ambiance, impressive visual weapon upgrades, solid sprite work, and affordable price point as a passion project. Players appreciate the focused hour-long campaign and streamlined gameplay, though some find the level design uninspiring, secret rooms frustratingly obscure, and the inventory-based progression system restrictive and frustrating for exploration-focused players.

Cthon is a pretty simple roguelike, with the graphics and action of Wolfenstein 3D (albeit with all ranged attacks here being projectiles instead of hitscan), and the story of Doom. The core gameplay consists of wandering procedurally-generated mazes, looking for the exit while fighting enemies with bare bones FPS mechanics, and managing and upgrading your ♥♥♥♥. You pick from one of three classes for your run through three chapters, each broken up into three levels, plus a final boss level. On normal difficulty, a full run takes about an hour. Each class specializes in one of the three available weapons, though there's some utility for all weapons across all classes. You develop your character by equipping items that upgrade your weapons' capabilities or your own, but you're limited in how much you can carry or use based on your energy reserves and inventory space, which themselves can be upgraded with the proper pickups, or with resource expenditures at certain shops. (If you've played 3079 Block Action RPG or System Shock 2, you already have some idea of how this'll feel.) I like how most of the upgrades will actually show up on weapons' viewmodels and the HUD when equipped, …

A minimalist first-person adventure that can be completed in under an hour. Get in, get out. Kill anything not you and upgrade your kit along the way. Creates a sense of dread through ambient music and a short draw distance. The real selling point here is the impressive way your HUD and equipment change appearance based on upgrades; this ain't your father's Wolf-3D. My only beef would be with the absolute obscurity of secret rooms; I dare you to find one. Also would have appreciated some achievements to extend the replay value. Overall well worth the small price tag to support an obvious labor of love by a single developer. Just don't expect it to reinvent the wheel.

I love the vibe of this game and it's quite well priced for what it offers, I just wish the levels were more interesting.
Not recommended Apr 1, 2026
My word, what a load of crap, i have never seen a boomer shooter so uninviting to exploration, nor one with such a c*ckblocking progress control. Whoever though of the inventory limit based progress for this type of game needs to find a day job
