New Update Out Now

Hello Everyone,

A new update for IHNMAIMS is now available which contains the following:

  • I have updated ScummVM from 1.6.0 to 1.7.0 across Windows, OS X and GNU/Linux.
  • opengl_nearest is the new display renderer. This provides really sharp looking graphics and also re-enables the Steam Overlay for Windows. It runs at your monitors current resolution.
  • I have completely re-written the shell launcher for GNU/Linux and implemented a new libraries system. This should allow for many more users of GNU/Linux to play the game and not just people on the latest versions of Ubuntu and Mint.
  • The scummvm-ihnmaims.ini file has been hugely reduced in content which should allow for the most vanilla start to the game in ScummVM anyone could ask for.
  • Launch parameters have changed. Instead of "ihnmaims" being used, it is now simply the ScummVM default "ihnm". This also allows users to save and load using the ScummVM menu (CTRL+F5 on Windows and GNU/Linux, Fn + F5 for Mac OS X). A Restart of your Steam Client may be necessary to receive this change and does not affect GNU/Linux.
  • The Modern ScummVM skin now works on GNU/Linux.
  • ScummVM source code has been updated to 1.7.0. SDL source code is now included.

Important! Because of specific changes in how ScummVM now works, your save games will need to be renamed. Simply go into the Saves folder in your IHNMAIMS installation and rename any "IHNMAIMS.s0x" file to "ihnm.s0x" and your saves will reappear. Apologies for the inconvenience.

I have been working with the ScummVM team to get to the bottom of the 'Characters disappearing on loading saves' bug that has been reported on the forums. The problem seems to have been solved or has gotten much rarer in 1.7.0 but it might still happen. If this does, I urge you to report the issue to the ScummVM Bugtracker and submit your saves to them for them to look at.

If you have been affected by the bug then, currently, there is no solution for the problem. You will have to load a previous save if you have one or restart the game if you don't. Apologies to anyone who has been affected.

Enjoy the update and thank you for playing :)

Based on the classic dystopian sci-fi short story by Harlan Ellison, this has some of the best writing you'll find in an old-school point-and-click adventure game. Ellison also provides some truly fantastic (especially for its time) voice acting as an insane AI.

The gameplay suffers from a number of glitches (though none that I saw made it un-beatable) and a very rigid, archaic game design. For example, a number of progression events will only occur after you say or do things that are completely unrelated to the event.

Unlike most adventure games of its time, there are multiple solutions to many puzzles...but usually only one "good" way. You'll have great difficulty getting the best ending (and yes, there are multiple endings) without a walkthrough. Of course, given the underlying subject matter, it's rather fitting that the (relatively) happy ending is elusive.

All that said, it's worth playing for fans of adventure games and especially for fans of the short story - as the game's plot is very different.

Depressive, sick and madness. I love this game.

If you are looking for challenging puzzles, this game is not suit. But if you are looking for something you may never seen, something new, so this is might a game you are looking for.

Humanity extinct at the hands of its own creations and the erradicator of our species is as insane as us! 4 lucky dudes and a dudette find out just how much for a millenia... and now they got a chance to escape (yeah not the good kind of escape but relative to their existence its a great deal).

Who needs 'depression quest' when you got 'SUICIDE QUEST'!

I Have No Mouth, and I Must Scream is a fascinating piece of work. It's one of those games, much like Scratches, that works wonders with atmosphere, but not so much when it comes to the actual gameplay. Although where Scratches had a really tense, frightening atmosphere, No Mouth is more mysterious and depressing. I Have No Mouth, and I Must Scream works more with fridge horror, I feel. Yeah, it's creepy, but it's only truly scary if you sit back and think about it. And you will, because it's a tale that provokes thought.

I Have No Mouth, and I Must Scream was originally a famous short story by one Mr. Harlan Ellison. If you get the chance, I recommend giving it a read, as there's a reason it's so famous. Actually, that's a lie. I don't recommend reading it. I really recommend listening to it. The I Have No Mouth audiobook, read by Harlan Ellison himself, is truly a treasure of audio. Ellison is hammy and over-the-top, but man does he sell it. The man gets completely into his story, and it benefits immensely from it.

If you've done the above, then I think you'll be more than pleased to hear that Ellison also plays AM, the maniacally hate-filled, torturous supercomputer who serves as your antagonist and tormenter for the duration of this game. He's every bit as hammy and over-the-top, and it's hard not to hang on his every word. The other voices in the game vary in quality, but you won't really notice the dips as you'll be too focused on the unfolding storylines, and also on WHAT DO I DO

So let's start with the story. You play five different characters, who comprise the entire remaining human population of Earth. AM, a colossal supercomputer which resides beneath the crust of the Earth, more or less got frustrated with his lot in life and unleashed the world's supply of nukes at... well, the world. But it kept five human beings alive to be his playthings for the remainder of eternity. For over a hundred years, these five humans have been subjected to ungodly torments, and now AM would like to play a little game.

Each character is thrown into a scenario built especially for them, expected to be horrible and miserable for AM's amusement. The true goal before you is to fail AM, and prove yourself above his petty games. It is in these scenarios that you will learn about each character, their faults, their history, and a little bit about AM himself and what's going on behind the scenes and beyond your view.

This obviously differs from the original story, as these scenarios never existed. They were created (with major input from Ellison) especially for this game in order to give more backstory on the characters. Things change. The story as a whole changes. But it's still very much I Have No Mouth, and I Must Scream.

Let's talk about the gameplay.

It could be better.

IHNM is presented in a classic SCUMM format. You have a list of verbs and an inventory at the bottom of the screen, both of which can be used to interact with the world around you. You will talk to characters, solve puzzles, find objects. All the familiar trappings of a good point-and-click adventure. So far, so good. The first major hitch is that eternal adventure game hellspawn, the unrelated event. You know what I'm talking about. When you do a thing, which triggers an unrelated thing to happen somewhere else which you have no way of knowing about and no reason to think might have happened. So many point-and-click adventures have fallen prey to this design flaw (Myst IV and Hector 3 among them, just thinking off the top of my head, here), and I wish it would stop.

I had one point in the first scenario I picked where I didn't know what to do. I looked up a guide, and it didn't help. I thought maybe my game was glitched, as I had done everything the guide had ordered. And then I saw it. A very subtle thing. A line in the guide telling me to exhaust a certain character's dialogue. All I had skipped (for reasons that we'll get to in a moment) was an entirely unnecessary rude line that doesn't actually help anything. But lo and behold, when burning off that one useless line of dialogue caused an unrelated character to appear in a different location, freeing progression from the devs' icy cold grip.

There are some other annoying bits, here and there. Some items and interactables that aren't exactly obvious on the screen. Two scenarios allow you to progress past important items or before doing mandatory bits. It's problematic, and very confusing when it happens. Luckily, it's possible to die after this moment in one of the scenarios, bringing you back to the character select where you can choose to try again. For the other one... well, just keep multiple saves, is all.

In addition to simply making through each scenario, every character has a personal spiritual meter. The better the spirits they're in, the lighter the background behind their portrait in the lower-left becomes. Practice good morals and make progress to lighten it. Screw up, be corrupt or evil, or just cause your character to freak out to darken it. If the meter turns white as the scenario draws to a close, you've perfected that scenario. This is not always easy to do. I only managed it in two scenarios.

They say you need to get a white meter with each character in order to see the best ending, and that's going to require either a guide or multiple playthroughs. I wonder, though. I'm pretty positive I did in fact get the best ending, despite not having all whites. I think it's probably possible as long as each character has almost a white meter, or a couple characters have white meters and everyone else is close? Or something? Though don't quote me on that, I really don't know, and there's a surprising lack of entirely helpful documentation on this subject.

Anyways, my advice is to not worry about it. Do your best and get an ending, whatever that ending may be. Give the finale a few tries, though, because you'll probably screw it up a couple times.

Anyways, point is, the game looks great and sounds great, and the story will draw you all sorts of in. Just be aware that you may need to consult the Internet at times, and be sure to rotate your saves. Or do what I did and just make each save a new one, because this game seems to have infinite slots. Which is a nice feature.

For all its faults, I still enjoyed the majority of my time with I Have No Mouth, and I Must Scream. And if you're a fan of the original story, or games which not only don't shy away from adult themes, but walk straight through a minefield of adult themes and take it all in stride with a sly grin upon their lips, then I think you'll enjoy it too.

This is the most twisted game I have ever played, you start the game with 5 tortured prisoners being held by a psychotic computer named AM (he is voiced by Harlan Ellison, the guy who made this game with Cyber Dreams & the book version that he wrote), it's a choice driven point and click adventure game so you can pick any character or decision you want.

As you progress through the past of these 5 characters you'll feel what they feel about themselves like for example Gorrister's Guilt, Ellen's pain, Benny's ignorance, Nimdok's desires for torture & Ted's lust. The main goal of the game is to either satisfy AM by making the wrong choices or you can fix the past by making good choices.

The whole point of the game is to lose, there is no hope for humanity & overall if you feel that games aren't dark enough then play this awesome classic. (Warning if your sensitive to ♥♥♥♥, torture, murder, satanism, sacrifices, lust and etc. then this game isn't for you)

UPDATE: I found this awesome interview from Night Dive's website about the game & some of Harlan's opinions

UPDATE 2: If you liked this game & you want to hear more from Harlan Ellison then I suggest taking a look at his youtube channel or his twitter (I thought Harlan was anti-digital but he's slowly liking technology & the internet)
