I noticed during this last raid a slight bug. Dunno if it has previously been reported but here goes neways...
If someone is tied to Kilican life monument during the raid and they manage to get back and are capable of doing damage to the demon assault troopers then they can kill the one that appears on the life monument regardless of how many times they die. Basically you have unlimited lives to kill it as you reappear in the smae location as the demon and are thrown instantly back into the fight.
Neways. Just thought you should know.
