Steam: it is basically a platform which allows the genuinely purchased games to be added to its application so when any game is added is associated with it then it can safely be launched and all the login details are managed by Steam Server from backend. This helps in preventing in loss of key and loss of login information and ofcourse you’ll experience a fair chance of play of various games on its respective servers. Free from all cheaters and hackers, as they call it.
and
Counter Strike: It is a multplayer online FPS game and it has been awarded several times for its addictiveness. Like i said it has many versions released so far
But definately there is no such game called as Steam strike but
so in a way we can state the equation as below
Steam Plateform + Counter Strike = Steam Strike.
