A friend of mine quit for the day during a LAN party when I no scope head shot him when I was in the air on a low gravity jump match map. I wish I was making that up because of all of the "360noscope" memes, but this happened back in 1999-2000. We regularly played instagib ctf matches on that map, with low gravity and jump match against godlike difficulty bots. Those were rough. But man were they fun.
