What are the best exploration based games on PS4?

The main focus of the game is hunting robotic creatures also known as "machines". They are similar to real animals in both appearance and behavior, so a lot of them move in packs. You have to be careful in how you approach them, because provoking one of them will also provoke the others.

You can hide in tall grass and attract them one by one with whistling. This way you can take them out silently with your spear, minimizing the danger.

Or you can get into a direct confrontation, which is a lot more intense when there are multiple enemies. You'll have to learn their patterns, so you know when to dodge or attack with your weapon (usually a bow or slingshot). When you finally manage to defeat them, it truly feels like an achievement.
