Have your biological head hit hard enough and your memories are erased all the same (and worse). If you're really scared of hackers, just don't connect your bionics to Wi-fi. But hackers can't do anything worse to a cyborg than a psycho with a scalpel can do to a human. Or a car wreck, or slipping on a wet bathroom tile... @ Heliocentrical: Abaddon is fantastic.

Can't say I agree with you on the bionic augmentation front; I want to be as much robot as possible. Related question: which Unreal Tournament 2004 character did you use?
