When you play on PC, you can't really 'see' what's happening on the screen. This is especially a problem when you're playing a first-person shooter or an action game. In those games, you need to look at the screen to see what's going on.

On your device, you can look around the world in first-person view. So you can see what's happening in the game world and also see the world outside of the game.

This is called the 'First Person View'.

In this mod, you can get a first-person view on your device. It supports proper shadows on your hands and equipped tools.
