I'm playing Mass Effect 1 for the second time with an imported character (Infiltrator, level 45).
Sometimes I one-shot every enemy that is in line of sight, but sometimes only their shield lightens up and they take almost no damage - even if I shoot them several times.
Is this a bug or do some enemies have advanced levels?
Summary of my question:
My shots even manage to kill a stationary geth shield and the geth behind the shield (both with full hp), but sometimes the issue as described above happens. I have to use another weapon and shoot several times until the enemy dies.
