Cobalt Enigma (C++ Terminal Game)
Built in 2019 November, Released (kinda) in 2020 March. By Madhan Selvaraj and Raghav Sriram
Cobalt Enigma is a terminal-based interactive fiction game that plunges the player into a post-apocalyptic scientific thriller, blending elements of cryptography, chemistry, and immersive storytelling. You awaken inside a mysterious containment pod, dazed and disoriented, in a world ravaged by a deadly neuro-virus known only as The Enigma. The environment around you pulses with eerie silence and blinking electronics, each component hinting at a long-forgotten catastrophe. As the sole survivor of a once-thriving laboratory, your mind holds fragments of memory — enough to log into a defunct research computer and begin unraveling the layered encryption left behind by your past self. The game's brilliance lies in its atmospheric buildup, created through a series of slow- and fast-paced typewriter animations, making you feel like you’re hacking into a decaying mainframe of a forgotten world.
The gameplay is structured around layered puzzles involving random number guessing, file directory simulations, and multi-stage cipher decoding challenges. You must navigate a simulated file system in search of a lost chemical key, correctly identifying a directory from a randomized set while preserving limited attempts. Success allows access to deeper journal entries — haunting logs that chronicle the slow demise of civilization and your own descent into illness and memory loss. With each successful decryption of encoded messages — inspired by real-world techniques like ancient alphabets, numeric substitutions, phonetic systems, and classical ciphers — the player pieces together both the story and the vital formula to humanity’s survival. But failure has consequences; incorrect inputs are met with eerie feedback, sudden endings, and the slow collapse of your last chance to save the world.
The entire experience is wrapped in a cyberpunk shell of decay and urgency, punctuated by references to scientific elements, encryption lore, and psychological unraveling. The final challenge, a memory test of all the previous clues and passwords, cements the game's identity as more than just a codebreaking simulator — it’s a story of identity, desperation, and responsibility. If you manage to reach the true ending, you are rewarded with a poetic closure, where science and sacrifice fuse together to birth a last flicker of hope in a dying world. Cobalt Enigma is not just a game — it’s a cerebral journey that invites players to think critically, engage emotionally, and reflect on the fragility of memory and knowledge. Designed for game jams and retro lovers, this piece of interactive fiction is a love letter to classic hacking simulations, cryptographic mystery, and dystopian storytelling.
