You can try to play Mobile PUBG. I think this game is pretty good. Furthermore, try playing COD mobile, but my friend told me that this game is only good while you are playing with an additional joystick. I would recommend you play the latest release of the Fortnite Mobile, the awesome part about it is that you can earn some additional skins or provide boosting services since this game is very popular. If you are a good FPS player, you definitely should try playing this game and selling your services at online gaming marketplaces like https://igitems.com/.
The best in my opinion is PUBG. It is the one that has given me the most hours. Another game that I liked is Dead Trigger 2, especially if you like zombies.
