Enter Sevastopol station in mission two. After checking in with the android, explore the station to find origami foil unicorns in various locations. This is a reference to another Ridley Scott film, Bladerunner, where Harrison Ford finds one at the end of the movie.
Play mission 6 to easily get killed at the start before entering the chambers.
Using the stun baton on human target counts as a kill. Avoid using that weapon. Using any kind of device (noisemakers, Molotovs, etc.) or having human hostiles shoot you to call the alien counts as a human kill towards "Mercy or Prudence?". Avoid humans at all cost.
Play under the Novice difficulty setting. Quickly open the menu before you dying in order to continue. If you actually end up dying, do not load the current saved game. Instead, use the second option to load the previous save. Although this will resume the game further back, it prevents the death from counting.
The hardest difficulty available was added through a post-release patch, and is not required to earn "Survivor". Instead, complete the game under the Hard difficulty setting.
