How Did the Marrowbreach Change in Subnautica 2?

This behavioral update makes the creature faster and more aggressive but provides players with a clearer charge telegraph and the ability to be outfoxed.
Unknown Worlds Developers, via Rock Paper Shotgun "While the Marrow Breach used to target the player's oxygen tank — a somewhat confusing target — it now targets the player's head, resulting in a new status effect: bleed."
