Horizon Zero Dawn

Note: This trophy is for scanning every machine type, but we've combined it to the other machine trophies. So while doing this, you'll be scanning and killing all Machines.

There are 26 Machines in the Notebook's () Machine Catalogue. This catalog is used to see what machines you've encountered, scanned, and whether or not you have their override unlocked. The catalog can also be used to view all Machine components and loot.

What you need to do is use your Focus Scan abilities to scan every type of machine in the game to complete the Machine Catalogue. Doing this will unlock the All machines catalogued trophy; however, since you're required to scan every single machine you might as well kill these machines as you encounter them. Killing machines will unlock the following trophies:

• All machines catalogued
• All Acquisition machines killed
• All Recon machines killed
• All Combat machines killed
• All Transport machines killed

When zooming in on the World Map it shows Machine Sites, which are spawn locations of the machines. Unfortunately, there’s no way to see what category a machine belongs to (they are divided into the four types: Acquisition, Recon, Combat, Transport). You’ll have to kill all as you scan them. Please note that all Corrupted Machines count as only "Corrupted Machine" and nothing else. This means if you kill a corrupted Rockbreaker it counts as a "Corrupted Machine" kill and NOT as a "Rockbreaker" kill! You must kill the normal uncorrupted machines. Additionally, the story related Behemoth won't count as a kill towards the Transport type. This means that you will need to kill another Behemoth machine on the World Map instead or during Side Quests.

These four trophies do cause confusion due to the lack of no real category. Thankfully, there is a way to tell what machine(s) you're missing for these 4 types. The best way to tell is by looking at your Notebook's () Statistics. It is here you can see the information of "Machines Killed" and there are 24 machines that can be listed here (excluding Tallnecks & Corrupted Machines). What you can do is count your Machine Kills in this order and if you're missing one, find it and kill it until you have all 24:

1. Watcher
2. Redeye Watcher
3. Grazer
4. Charger
5. Strider
6. Trampler
7. Glinthawk
