All ID Tag locations

Search the indicated locations to find all 50 ID Tags. Collect all 50 ID Tags to get "The Taken" achievement. You can view which ID Tags you have collected under the map menu. Each ID Tag has its own name, which allows you to easily keep track of which ones are missing. The ID Tags are saved automatically when you collect them up. Thus, you do not need to collect them again if you die. Use the mission selection to obtain any missed collectibles.

All Nostromo Log locations

Search the indicated locations to find all 10 Nostromo Logs. Collect all 10 Nostromo Logs to get the "Archivist" achievement. You can view which Nostromo Logs you have collected under the map menu. Each Nostromo Log has its own name, which allows you to easily keep track of which ones are missing. The Nostromo Logs are saved automatically when you collect them up. Thus, you do not need to collect them again if you die. Use the mission selection to obtain any missed collectibles. You should get the first eight Nostromo Logs in Free Roam during Mission 16. Simply load Mission 16, and ignore the main objective. The reason for doing it this way is that you need all of the tools that are unlocked later in the game. You get the level 3 access tuner in Mission 15. You can only get all Nostromo Log after this point. Certain tools are required to open doors. The way free roam works is that there are four Transit Stations: Lorenz Systech Spire, Sevastopol Scimed Tower, Solomon's Habitation Tower, and Engineering. You can travel between these areas using the train station (there is a red sign above each station that says where the train is going). Each of these areas have elevators that take you to the other side areas, such as Seegson Synthetics. When you scroll over an elevator on your map and zoom in, you can see where it will take you.

Blade Runner reference

Enter Sevastopol station in mission 2. 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.

Easy "100 Times Too Many" Achievement

Play mission 6 to easily get killed at the start before entering the chambers.

Easy "Hide. Run. Survive." achievement

The part where the "Hide. Run. Survive." achievement begins is when you access the computer in Morley's office in Mission 5: The Quarantine. This is your main objective and unmissable. The Alien will then drop from the vents above. You cannot ever run or it will hear you. Only walk and crouch. Also, use your motion tracker to see the current location of the Alien. All you need to do is grab Morley's keycard from the corpse in Room A-29, then exit the area. The entire encounter will take around three minutes. You will get the "Hide. Run. Survive." achievement at the end of the mission. Note: If the Alien does see you, or is about to kill you, then quickly restart from the checkpoint.

Easy "Mercy or Prudence?" Achievement

Using the stun baton on human target counts as a kill. Avoid using that weapon.

Easy "One Shot" Achievement

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.

Easy "Survivor" Achievement

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.
