I Havn't seen it yet )=
The first i fought Dr. Sal was sort of scary..
The damn guy wouldn't go down..
The first time i finally killed him was with a lot of shot gun blasts, a few grenades and a lot of hand gun head shots lol.
And then, i encounter him in the ruins and he went down easy.. Amazing what a good gun can do lol..
