Critical Ops continues to be one of the primary shooters on mobile. With its classic first-person shooter concept blending with a more modern design, it's a highly regarded game, even with a huge hit like Call of Duty Mobile leading the charge. 

If you're a fan of CODM or Counter-Strike, then Ops is certainly a worthy alternative. And as mentioned before, it continues to be one of the most recognizable games in mobile esports. Only Clash Royale, PUBG Mobile, and Brawl Stars might be bigger in the scene. 

And although some aspects of the game are pretty straight forward as an FPS, there are still some ways you can approach your play style. And some of these you can apply to other games that are similar. You can play any way you like, but it can always be fun to follow a certain playstyle.
