Horizon Zero Dawn

Skill Required: Strike from Above

You must first purchase and learn the skill called "Strike from Above" from the Prowler Skill Tree. This skill costs 2 Skill Points and whenever an enemy is standing below you, press to silently drop down to instantly kill small machines and humans. If this move is used on medium sized enemies, it will only deal high damage.

For the trophy, you will need to use the "Strike from Above" to kill at least 3 enemies in order for this trophy to unlock. It doesn't matter if these enemies are machine or humans as long as you killed them using the Strike from Above skill. You can easily get these kills by throwing rocks at the ground or using the Lure Call skill to lure a machine like a Watcher or Strider to your position. As they get closer to you, climb up a small cliff or hill platform. You should then be prompted to press if you're in a position where you can drop down for the kill. Rinse and repeat this method 2 more times and the trophy will unlock on the 3rd enemy killed.
