i dont think counter strike matches cod4 for anythin heres why cuz cs is the most unrealistic/realistic game ever made sure the guns act like there supposed to but the enviorments and players lol never do. in a real battle u should be able to do more than just crouch no going prone no meleeing with your weapon hardly any cover no fog of war for being so supposedly accuartly realistic it misses those key points if u wanna be good in counter strike simply be the faster better shooter it is very limted in its startegys just if u can shoot faster u usally win i tried to employ diffrent tactics on cs but they lack the necessary tools to make them work such as going prone bein able to hide battles arent just won by whos fastest which is usally how cs battles r won there won by startegys which cs dont apply that often
