Hitboxes are tricky things in any sort of competitive game. Broadly speaking, hitboxes are the spaces around a character that can be hit by attacks (or hazards or whatever). Problems arise, however, when a character’s hitbox doesn’t line up with what you see on-screen… which brings up the problem of Pathfinder in Apex Legends, who appears to have far too much hitbox and is thus easier to hit than the model would imply.
The extra space has the deleterious effect of making the fast and agile character easier to hit, and also just feels weird (if you can see that you’re shooting at open air and still scoring hits, the game doesn’t feel right). Developers have stated that they’re aware of the issue and are looking into it, but there are no announcements about it just yet, which means that Pathfinder players will probably need to endure outsized hitboxes for a little bit longer.
Meanwhile, players have uncovered nearly a dozen new hero names listed in the game’s files, which would more than double the game’s current roster. So on the bright side, perhaps your options for “quick and agile” will spread out significantly sooner rather than later.
