How to unlock the Perfect Organism achievement in Aliens: Dark Descent - Definitive Guide

Just some info and advice

“No one can hear you scream” isn’t a difficulty per se and as such it could be done in conjunction with any difficulty options.

This mode limits your saves.
The only auto saves you get are:
* on the ship
* when resting in safe rooms
The latter will be the majority of your saves but these cost “tools” to weld the door and initiate the save.

A good number of tools can be found on each map and any spares you have at levels end go into your reserves and if you run out of these on home base you can spend resources to buy more.

It’s really not that bad as you should be resting in safe rooms to keep your stress levels down often.

Had I known how to play the game from the start, I would’ve done this mode on my first playthrough as it’s fairly straight forward.

Tips:
* Use stealth (in all play throughs).
* Scavenge (but if there’s too many enemies, it’s fair to let some items go).
* Drop portable motion trackers regularly and far apart so you can activate them and make the xenos run all over the map when they approach your position.

.
Remember, during NG+ campaign selection, it appears that custom can be selected and the timer can be turned off. So you can skip as many days as you like even after Cerberus Protocol and achievements unlock.

Someone else please confirm.

UPDATE: Confirmed.

The countdown difficulty can be customized to no threat, thus no time constraint of days passed on the Otago, IF NOT PLAYING ON A HARDER DIFFICULTY.

My achievement unlocked just fine.

I don't recommend attempting this on NIGHTMARE because that difficulty forces you to have only 20 days remaining after the cerberus protocol attempted deactivation.
You will need to be able to save frequently without having to return your team back to the Otago, because as you know "DON'T LET THE HEAR YOU SCREAM" greatly limits when the game saves.

Did on easy difficulty. Some mssions are little hard, but doable. Resting helps a lot

Do elevators initiate saves as well?

No. Only on the ship or when you weld yourself into save rooms. I think on the mission on the ship you get a few checkpoints seeing as there’s several people insta fails.

Be careful! There is a catch in the description of the trophy.
When you start a new game, there are 4 difficulties: Story, Medium, Hard and Nightmare. Plus the fifth is that you set various parameters yourself, it’s called “your own”. Having not seen the “No one can hear you scream” difficulty level, I started the game on Nightmare, thinking that this difficulty would open after the first playthrough of the game, as is often the case, but this is not the case. In fact, this is not the difficulty level of the game as such, but an option that increases the difficulty of one of the four available levels. To enable this option, select the level you want to play on, then select the YOUR section, there at the very bottom there will be a save options item, there are two sub-items in it, and one of them is “No one will hear your scream.” All this is done only immediately when creating a new game, then you will not find anything like this in the options. This function gives you only one save slot per mission, so don’t even think about combining this option with the nightmare level, it’s simply impossible to pull it off. Only combine with the plot level of difficulty, my advice to you.

A nice bonus: saving through resting in brewed rooms is available even with this option. That's why wrenches are your best friend on this walkthrough.
