Nightdive Studios releases “Definitive Update” on PC for classic horror adventure I Have No Mouth, and I Must Scream

From Press Release:

Following a console release last March, industry-leading remaster developer Nightdive Studios has announced the release of the “Definitive Update” for Harlan Ellison’s I Have No Mouth, and I Must Scream. The update is currently available on Steam and GOG for Windows PC, Mac, and Linux. The “Definitive Update” features various technical improvements from the game’s console release, including enhanced controller support, new display options, bonus content, and more!

Based on the post-apocalyptic short story by renowned author Harlan Ellison, I Have No Mouth, and I Must Scream plunges players deep within the center of the earth, where they play as each of the five survivors who have been trapped in the bowels of the insane AI AM for the past 109 years. Fueled by his intense hatred for the human race, AM has spent the past century torturing and toying with each character as he sees fit, culminating in a final game: an appropriately meta adventure-style quest for each of them, teasing the prospect of freedom if they succeed.

Each victim is subjected to a personalized psychodrama designed by AM to explore their greatest fears and feelings of guilt. Players go through each character’s personalized scenario, discovering the truth about each of their pasts and why AM chose to keep them alive and prolong their suffering. Whether they have the strength to overcome his games and face their demons…well, that’s for the player to decide.
