I saw what had to be done, and this leapt out at me as the most obvious and plausible choice for it. After all, even though they were the villains, the Anti-Fun-Pro-Dominatrix evil organization WERE the ones in charge. Every CD used to take down one of their minions was a terrorist's tool, at least in their propaganda.
Also: "I don't understand how anyone could kill someone with a CD."
The worst Operation World clone ever made. Bullshit cheap shots you couldn't avoid, bullets did dick for damage so you had to use CDs on everything which you quickly ran out of. 50 cents bought you 10 seconds of shooting CDs until you ran out and died again.
Plus I think you had to do some impossible secret shit to get the real ending.
