Just in case you weren't put off by the lack of any kind of mention of Valve Software, advance warning of the game's arrival or the complaints demanding their money back, if you see a game called Counter Strike on the App Store, don't spend $2 on it.
Unless you enjoy being ripped off by fraudulent scamsters. In which case, who am I to tell you how to spend your money?
Counter Strike [App Store, thanks unexpect3rd!]
