This is Counter-Strike 1.6 running just fine on a mobile android. with servers and everything.
Its not that much of an ideal way to play counter strike.
The touch controls look like a pain, but this being Android, it’s not going to be hard hooking proper peripherals up to your tablet/phone if you need more precision.
Note that this is actual CS 1.6. Not a recreation, not a stream, but the game itself running on the mobile OS. Making things even more impressive is that it’s made by this guy, Alibek Omarov.
If you want to try it out, you’ll need 1.6 in your Steam account for some of the necessary files. For everything else you should check ,here.
