Res ipsa loquitur.
It reminds me of "Dark License to Kill" from Goldeneye 64 -
http://www.gamefaqs.com/boards/19746...e-007/65989446 .
You set enemy health to 1000%, enemy damage to 1000%, enemy accuracy to 100% and enemy reaction time to 100%, then you use geometry exploits, close-circle strafing exploits, hugging people so tightly they shoot past your hitbox exploits, and interrupt animations to try and complete levels.
It was, and is for those still playing, a "challenge", but was about the least enjoyable experience ever.
