I've been trying to do the first mission ghost and clean hands, i've done both separately but can't get them together - i think i am killing the two guards with the door explosion in the prison exit but it's so random - sometimes i kill 1, or 2, it makes no sense, i knock them out and hide them in the container but they seem to die - i am going to keep trying but it seems really fucking bugged and no google searches show people having this problem. at this stage i am running through this level knocking out only those 2 guards (otherwise they see you when you blow the door no matter what you do), got my time down to about 5 minutes which is fucking world record quality at this point but i always end up killing someone.
it's cray retarded.
/edit turns out by 5 minutes i meant 8 minutes
