Why do you need a companion app or guide for Apex Legends? Because you can’t possibly browse through the game to know everything about the weapons, characters, abilities, maps, etc. For example, you want to know the locations of the guns, the number of bullets, how the weapons work, what the different guns can do, etc. But you can’t do that on the game itself. Or maybe you’re just bored with the game. It doesn’t matter! So, it’s time to download this companion app for Apex Legends.
