But the general trading of headshots... theres nothing wrong with that.
You shoot him, he shoots you. You both die. What's wrong with that?
Normally I don't care too much but the ones that bother me is when I shoot someone, he clearly dies, then a full second or two later suddenly I'm dead from a headshot by that person.
Regular mutual headshots also shouldn't be possible on a hitscan system since the bullet travels at an infinite speed. Both people would have to pull the trigger and fire at the EXACT same time, not even .0000000000000000001 of a difference. Which theoretically is possible, but not this much.
But I guess I have to enforce this again,
I love Reach, and I have a great time playing it, but I don't play it nearly as much as I normally would because of scenarios like what happened to me in that video are extremely common. If it was a rare phenomenon it'd be OK but it's not.
