Not any more. Like I said, my memory card got erased. But I actually had 4 cards. I think there were more though, coz that cheat didn't open up, and it says it opens up when all the Exterminator cards are unlocked. Anyhoo, when I unlocked the Eviscerator one (for getting 100 nanobites as health or whatever threy're called) A little message popped up saying I'd unlocked it, but I'd unlocked Reactor at the same time and it didn't tell me how I did it. Bummer, eh?
