alright.... ill help.

these characters need to be loyal:

Legion- tech specialist

Garrus- 2nd squad leader (both times)

Samara- biotic specialist

Jacob- escort

use these characters and nobody should die. ideally... everyone should be loyal. if they arent, i make no promises. however, if they are, and you use these characters in those positions, no one on your team will die, nor will any of the civilians.

i used the exact same configuration except Tali for the tech specialist- everyone was loyal. But Mordin died. Is it random?
