All items for collection are marked on the mini-map, unlike in the previous game. The guide describes the ways to collect them, so the guide skips the detailed description of locations.
In this part they added one more collectible - purple enhancement chips. They are not hard to collect all of them without hints, because they are not hidden.
The number of the artifact in the guide refers to its number in the game, so the collection is not linear. In each section I will explain in what sequence I collected them in a location (if the locations are non-linear).

You will receive the following achievements for collecting all the collectibles:

• Live By The Sword
  
• Eavesdropper
  
• Garbage Man
  
• Chewing The Scenery

The item counts as found immediately after finding it, it is not necessary to complete the mission. You can find out what items you haven't collected in the mission selection menu. You can view the collection progress in your inventory at any time [TAB] -> [ARMORY] (swords) or [CODEX] (artifacts and audiologs).
