The punisher for PC
 

I just purchased the punisher off of ebay for my pc and have received it. However, i would like to know before i leave feedback, if the game has 4 discs, or three discs in its original form. The reason i ask this is because, the disc cartridge, has four slots, and only three cd's were sent? So any one who purchased this retail game before can you please tell me how much its supposed to be......
