shiz...you can download CS off of
www.counter-strike.net but it won't work becuase you need half life, half life has all the main info needed for CS, like gameplay and **** like that, all CS is basically is modified weapons and character models. and new maps. so you either go out and buy half-life or buy CS...either way you'll ned the full retail version of one of them...and a CD-Key if you wanna play online anytime without disturbances...and CD-Key generators don't work online, they are used only to play single player.
