The only things that can destroy auto turrets are hard to figure out, but I have found this: well aimed artillery fire, guided missiles, aerial bombing, explosives, similar.
Idk if a rifle will take out auto turrets. I looked it up a lot when trying to figure out how to get past them and only found videagame stuff. Anyway, I could teleport! Charge 15 secs n boom, you're at the end of the hallway next to the door, for example. But in order to keep the mission going maybe taking those out as a team might be a good scene element. Meanwhile, Rizzo's at the wheel at the door, taking back to the Eucharis to figure out how to unjam the door. Hopefully he also answers Princess Masumi, too. Just an idea, or we can have it that he knocked them out with thunder and lightning.
Hope that block of text isn't too daunting, sorry for making my IC ones that way, too.
