If you're like us, you got and see once you learn that you can mount certain enemies in Horizon Zero Dawn. You may be wondering where you can find these writable enemies, and how many different types there are. If so, you've come to the right place.
Overriding, which is Horizon Zero Dawn's term for mounting, is expanded over time. As you visit various cauldrons, you'll unlock access to a greater breadth of enemies to override.
Although there aren't that many enemies that you can override, there are enough that you'll see progression throughout the game. With that said below you will find a list of enemies, at which cauldron you will meet them, and whether or not they are mountable.
