Thanks to Dav1x, I have a copy of Postal 2. I spent several hours last night delving into the insanity that is this game. A virtual killing spree of gargantuan proportions.

Postal 2 is the sequel to the horribly violent game Postal, released in 1997, in which a man goes insane, dons a black trench coat, collects a cadre of weapons and blows the shit out of any and everything that moves
