This trophy requires you to complete all locations within the game. Locations are essentially any side activities in an area which aren't side quests. Incredibly there is no in-game progress tracker for this, however pressing  on your world map allows you filter "Uncompleted Locations" to view only what you have left to do. Synchronize a viewpoint in the area first to reveal all uncompleted locations. Be aware even after synchronizing a viewpoint that some locations may still show up as Question Mark symbols until you arrive to that location.

When at places such as camps, be sure to loot items in the area to make the  Reduce, Reuse, Recycle trophy easier in the end. Remember that you can hold down the  button to scan the area for items you can loot.

Important: Be sure to look out for Silica, which are the small, gold glowing objects that you can typically pick up in tombs and pyramids. You will need 50 Silica to activate the pillar at "Eesfet Oon-m'Aa Poo", a cavern under the Sphinx in Giza. There are more than 50 Silica in the game and if you don't have enough after getting all locations, you'll simply have to go back to tombs to find scattered around those tombs.

Below is a list of the types of locations that you will need to complete in order to receive this trophy:

• Viewpoints: These are located on the map once you have defogged the regions map by entering it. Simply climb to the top of its location and press  to synchronize the viewpoints. These will also show all other locations in the area and should be completed first.
• Camps: There are usually 2 - 3 camps found in a region, to complete these you must kill the captain and/or commander, and loot the treasure within the area.
• Treasure Locations: These can either by underground, underwater, on ships, or on land. Find all the treasure chests within there area to complete the location. Senu can help you locate these treasure chest locations.
• Lairs: There are many different types of animal lairs within the game, such as Hyena lairs, Ibex lairs, Vulture lairs, Lion lairs, Crocodile lairs, etc. These can be completed by defeating the animal leader.
• Papyrus Pages: You will need to find the papyrus page to complete this area. Luckily you don't need to solve any of the puzzles related to the papyrus pages in order to receive this trophy. You just have to find and simply pick up the pages.
• Stone Circles: There are a total of 12 that you will need to complete, and these do not show on the map after synchronizing a viewpoint. Refer to   Stargazer to know how to find all locations and how to complete them.
• War Elephant Camps: There are a total of 4 of these. Each camp will contain one elephant that you'll need to defeat, except the one located in Uab Nome contains 2. It is recommended to be at least level 39 before attempting these camps as the Elephants are level 40.
• Hermit Locations: These are resting places for Bayek, you will receive an ability point at each of them. There is a total of five and to complete each one simply find the resting location and press  to rest. Refer to  Words of Wisdom for more information.
• Pyramids and Tombs (Gold Question Marks): These are typically locations that ask you to enter a tomb or pyramid and find a stone tablet inside. They are labeled as a golden question mark on your map if you haven't entered them yet. This includes the "Eesfet Oon-m'Aa Poo" cavern under the Sphinx in Giza.
• Bureau of the Hidden Ones: You must complete all of the main story quests (side quests aren't needed) and then this location will unlock in Memphis.
• Locations You May Miss: Places like the Abandoned Fishing Village, Hotep Cavern, and Dionysios Warf are possible locations that may not show up on your map unless you happen to travel near them.

Glitch Warning: Before patch 1.10, it was known that during the main story quest 'Aya: Blade of the Goddess' that if you complete any of these locations it will lock you out of achieving this trophy. This glitch is now fixed. Patch notes can be seen here.
