I just had a Scylla fall on one of my team and was unable to move him. It was a heavy so no jump jet or movement. I am running version 1.6.61122. I was not able to destroy the corpse with Thor or Fury rockets, nor was I able to shoot it.

Scylla corpse is destructible just like Chiron's are, and i'm pretty sure every Citadel map has at least 3 Exits, sometimes 4. It's part of the strategy that if you're blocked, you just have to find another way out.

I thought her corpse WAS destructible? I know the Chiron's one is; I was able to disintegrate any part of their body, especially their abdomen, just by hitting it hard enough. For me, it was a Hel-2 Cannon shot that did it.

Second this. Annoying, if you don`t have any nades left.
