Ok I got Raven Shield.
Trying to do one mission where you can't kill anyone, and no one can see you. In a penthouse or something.
Really tricky. I'm even using the pre-built plan, and i get to a staircase and it says hold alpha blah blah. But the trouble is I don't know what I'm holding for. Obviously I'm waiting for a time when no one can see me, but even using the heatbeat sensor I still don't really know. how far away these beats are. Usually someone sees me from behind at some point.
Did anyone else find this very frustrating?
The other missions are ok, you can flash 'em. Or let your other team members take the tangos out!
