Much to the enjoyment of the die-hard Z fans, Steam and Good Old Games (GoG) have just released the original game. While you need a Steam account to play Z from the Steam site, you can just download the game from GoG and install it locally on Windows XP/Vista/7/8.
Both sites ask for $6.99 for the game which I was happy to spend to get that awesome feeling back hearing my bots scream at me.. “For God’s sake, do something!”.
