In this video I go over resources and how to acquire metal from caravans. Resources are required to upgrade your various weapons and armor.

In order to use the hidden blade on higher ranking enemies you will need to upgrade it otherwise you'll just attack an enemy without killing them which leads to more enemies being alerted.

Here I show you how to find iron using your eagle Senu. Eagle vision is not the same in this game as in the previous Assassin's Creed games. In order to mark enemies you need to use your eagle by pressing up on the D-pad and he will automatically spot resources.

You can tag the resource you are looking for and then go after it. Caravans are the best place to look for metal such as iron and bronze. Instead of using my melee attacks or bow I decided to try sleep darts. It's quite effective and you can farm metal resources with ease.

Another location to find metal is aboard ships and they usually carry more. If there is a particular video you wish to see please let me know in the comments below.
