You might see a lot more people using Gibraltar in Apex Legends soon. A new exploit has been discovered that makes him a force to be reckoned with. It all has to do with his shield, which people have discovered has perhaps unintended perks.
When you play as Gibraltar, he brings up a shield when he is aiming. It turns out, teammates could take advantage of that. If someone is playing as Octane, they could put a Jump Pad on the shield. A team member who is using Caustic could apply gas traps. These could then be combined to create Apex Legends exploits that make Gibraltar a more exciting character. If Gibraltar has the Jump Pad in effect, people could aim down, leap, and have him reach new heights. If the gas traps are placed on the shield, Gibraltar can barrel down with gas, basically steamrolling enemies.
While there has been no official word from Respawn about this Apex Legends exploit yet, some members of the team have been commenting on Reddit threads showing off Gibraltar's new abilities. For example, one video showing some good Gibraltar and Caustic teamwork had a member of the team that goes by 2BuiArt laughing at the clip. People then commented asking for it not to be "fixed."
This Apex Legends exploit is still in effect, so maybe try getting on a team with a Gibraltar, Caustic, and Octane to see how it works? You could have a lot of fun with these new tricks!
