Have you ever had the urge to play Counter-Strike 1.6 on your Android device? Probably not, but if you ever do feel the need to move from your huge monitor to a much smaller screen for some multiplayer action, now you can. The full game – maps, servers, everything – is playable on the mobile operating system. It uses a device's touchscreen controls, which, as you can imagine, isn't the best system for a first-person shooter. But you could always attach a couple of peripherals to your mobile/tablet to make things easier.
