There are five achievements in Alien: Isolation relating to not doing certain things:

Mercy or Prudence?
Completed the game without killing any humans

Just out of Reach
Contacted your team and escaped Comms without being attacked by an android

Hide. Run. Survive.
Completed "The Quarantine" without being killed by the Alien

One Shot
Completed the game without dying


Mind Your Step
Navigated Reactor Maintenance without dying

For any of these can you still get them if you:

  • Quit and reload before the animation completes
  • Reload a checkpoint
  • Reload the previous save
  • Reload the mission save
  • Restart from the mission?

Or is the only option to restart the entire game?

  • I can confirm that Just out of Reach and Hide. Run. Survive. can be attained by quickly loading the last checkpoint before the working joe or Alien touches you. I can also confirm that if the Alien does kill you the last save is updated but the level save doesn't appear to be, so reloading the mission save should work.

  • I can also confirm Mind Your Step is attainable by loading the previous save after you die.

After completing the game I can confirm that the following works for all of the above except Mercy or Prudence?

  • If you're quick you can hit pause and reload before you die. You'll see a tape icon in the top right if you're too late.

  • Certain late game enemies (from the reactor maintenance on) will not let you pause once the death animation starts, so be very careful around them.

  • If you're not quick enough then the current save is compromised, however the following works:

  • Load the current save

  • Then pause and select the previous save

Note that if you get killed before you save again you'll have to go back to the mission save.

For Mercy or Prudence? it appears that you have to load the mission save at least, but I can't confirm that as I didn't kill anyone.


For "Just out of Reach" when android attacks you just load last (current) checkpoint. Works for me. Been attacked once by that laying android , load current and after finishing I get the achievement.
