Gibraltar is the tank of the Apex Legends universe with two different shield abilities. He has a massive dome to protect himself and his teammates as well as a gun shield to block a large portion of his body when he aims down sights. He's a powerful 1v1 character, but there is one overpowering problem.
Most shields have carryover damage, if the shield has 30 health left, and a single bullet does 45, 15 damage will transfer to the actual health of the character. Not so with Gibraltar's body shield. As long as there is one health remaining on the shield, it blocks the full damage of the next bullet. There is no transfer.
Respawn Entertainment is aware of the issue and working on a fix.
"Unfortunately, a couple of meaningful tweaks to the gun shield just missed the cutoff for next week’s patch: (1) Bleed through and (2) damage counting towards stats/evo to mitigate some of the shield economy difference in poking engagements against a Gib."
Sadly, the change won't arrive in Season 8 as Respawn discovered a bug to the gun shield when noticing damage from a single compared to multiple targets. Once that is fixed, they plan to implement the change to balance Gibraltar a bit more.
