Hey guys,There is a total of 7 hidden achievements and 4 of those are unmissable story progression achievements. This leaves "One Shot", "100 Times Too Many" and "Run.Hide.Survive" but you'll get "Run.Hide.Survive" while doing "One Shot".Hopefully in this guide you'll find everything you need to finish off those last hidden achievements If you enjoyed this guide or found it useful please give a Thumbs up or Favorite and if there's anything i missed or you didn't like, leave a comment on how i can improve :)

To achieve One Shot it requires you to finish the entire campaign without dieing once. At first this might seem like some epic BS but you're actually able to load your current save file before you are killed and still have the achievement count as long as you never reach the death load screen.If you do reach the death load screen it saves your current death but you're then able to rewind to the "mission save" of the current mission you're in and still count as having no deaths.

• When the death animation is happening hit ESC and load your current save. This will negate the current death
• If you're not quick enough at hitting ESC and you are killed just simply reload a "mission save" and redo from the beggining of the level you died in.
• Watch out for Synthetics when on low health and if they do grab you and you don't have enough health to survive it, hit ESC and reload before you die.
• Also watch out for Face Huggers. It's possible to hit ESC before they kill you but their death animation is extemely fast.
• Saving often and playing on easy will save you a bit of time and allows you to be more reckless like running through gun fire.

Here's an example of when to reload to avoid a death counting:

This achievement is basically just a grind by letting the Alien kill you 100 times. It can be done pretty much any time you can encounter the Alien but here is a few tips that might help speed it along.

• It has to be the Alien that gets the kill, watch your health when around humans.
• "Mission 17 - Desolation" is a great farm spot because you can load it anytime and there's a Human right there to help attract the Alien.
• "Mission 18 - Tomorrow, Together" is another awesome farm spot shown by fold Jarl in his Youtube video that i'll link at the end.
• The Alien death count stacks with multiple playthroughs, saves and DLC.Credit - ??т??!т!zє?? vs Alien OO for confirming multiple playthroughsCredit - Leonesaurus for confirming DLC

Here's my example of farming Alien deaths:Here's fold Jarl's video on farming Alien deaths:

If anyone can confirm If you're able to reload a previous save rather then starting the entire level you died in again i would greatly appreciate it. :DThank you for taking the time to read my guide and i hope you enjoyed the read.I would greatly appreciate a Thumbs up or a Favorite and likewise if you didn't enjoy a particular part of the guide please feel free to leave a comment on what i can improve on.
