So the headhunter autoguns seem to have an issue, and its unclear if its a hit registry bug, or an issue with the stagger animations. But effectively if you use the headhunter guns to hunt heads, the second shot in the burst almost always misses even with a full stability roll. The only way to get the full burst to hit is to aim for the neck and let the second shot hit the head with the recoil. Its not entirely clear whats happening here, if the neck jerk animation is making the second shot miss, if the hit box is bugging out, if its hit reg issues, or what. But no matter what it makes the weapons counter intuitive to play and needs to be fixed. Which is a shame cause when you actually can get the Agripinaa IX to hit both head shots its one of the best guns in the game for a zealot.
It is pretty funny that the Headhunter is close to useless for Hunting Heads
