the wilhelm scream actually is in gta 4  there is a scream that sounds like it but the actual scream itself happens only once in the whole game its on a mission called the "final interview" where you kill goldberg in his office,once youve killed him and got the files go outside the office there should be more gaurds (kill them) and once you go down the first staircase at the top of the other one there is another guard shoot him in the leg once (with a pistol) he should dive down the staircase then he will do the wilhelm scream. very funny. sometimes he does'nt fall or the scream doesent happen be patient keep trying and he will eventually do it.
