https://forums.playcontestofchampions.com/en/discussion/286883/guillotine-2099s-sp3-deals-77-billion-damageThere's already been a thread on this a while back, feel free to check it out.From what I recall, the conclusion was that that's the highest number in-game, and there's not going to be a health pool higher than that, so it's there to ensure, without doubt, that the opponent gets KO'd. It's similar to shooting a body multiple times, just to make sure. Basically overkill.
