#1 Mobile 5v5 FPS Game , Call of Duty : Mobile

You should start playing Call of Duty right now!
Call of duty or CoD is a really popular competetive mobile first person shooter game which is increasing in status each day. You can play in various maps with lots of different weapons to choose from. You can play with your friends or you can play with random teammates depending on your choice at the moment.

You will be addicted to it if you love competetive fps games. Call of Duty is also a favorite game of mine. CoD has hundreds of different character skins and guns. Last time I checked there were more than 80 guns. If you'd like to go even further you can complete mastery camos such as Gold , Platinium , Damascus. You can unlock gold on any weapon but for damascus you will need yo unlock Golden camo for every weapon in the game.

There are also micro transactions but you won't need to pay for winning the game because skins have no effect on winning the gunfights.
The game needs at least 12GB of storage and 3GB RAM to run it. The graphics and designs are top tier so you will have freezing issues with a low end device. You might even need to delete some apps to download it if your storage is maximum 32 GB. Due to Sony's sponsorship last year the game is perfectly optimized for Sony Xperia III.
Be careful for your own mental health because if you get addicted to it you will experience toxic mood and mind.
Play the game safe , Have fun.
