I'm nearing to the end part of the Citadel DLC. Been fighting with the clone Shepard in the cargo bay. However, there is no way I can kill him. His shield is always at full charge.
Anyone facing this?
I went back through on several play-troughs and Mr Biscuits is right, you have to take down the Clone's shields and armour untill he runs out of Medi-gel, Engineer is the easiest due to Overload and Incinerate Fire boom combos, I did have some trouble with the Infiltrator play-through with him not taking any damage at all but i think the trainer was causing an issue there, either that or i wiped out his gel count too fast and it glitched.....either way, just keep shooting him and he will go down, other than that focus on Brooks for a little while.
Hope that helps
