Yes, I dread that special assignment as well. It was originally going to be an ET and I’ve noticed there are quite a few that don’t seem possible or are extremely difficult. These are some I already tried but haven’t found a solution for:
The Deceivers (I managed the Guru, but the Congressman I haven’t been able to isolate without using rat poison on the wine)
The Stowaway (He’s an enforcer to your own suit but you need to approach him in order for him to move, which he has to do if you want him alone)
The Cannibals (still hopeful this can be done, the Chef is easy but the Embalmer haven’t managed…yet)
The Revolutionary
The Blackmailer
The Bookkeeper (I tried once but I don’t think I will try this one again
)
The Chameleon (even making abstraction of the accident requirement)
The Entertainer
The Sensation
The Surgeons (because of the injected virus requirement)
The Warlord (getting to the safe)
The Appraiser (getting the book seems doable though, so still hopeful)
The Liabilty
These are some I managed:
Illusions of Grandeur (;-))
The Broker (pretty proud of that one, getting to the safe and isolating the target are not so easy but I managed. Lure away one of the safe guards with a briefcase, throw breaching charge at safe to open it, the other guard doesn’t move but can be distracted by a coin. The target I got near the spot where the Christmas burglars meet, after distracting his guard with a dropped Gun as well. Depending on where he finds it he takes it away himself)
The Forger (easy, near the start of his route in his study, drop a gun for his guard to find)
The Rage (need to manipulate his guard and one near the container outside to change the timing of his route, then you can get the Rage when he steps outside the double doors during a short window of opportunity and hide his body)
The Fixer (well, you have to KO the courier, no way around that, but the rest is quite manageable, following a similar method as for Strandberg)
The Censor (in the bathroom, quite easy, near the start)
The Identity Thief. (At some point he will go backdown from the auction alone, so you can get him on the stairs)
The Ascensionist (you can isolate her in the bathroom of the black gold bar)
The Heartbreaker (give the folder to his clients and lure him near the crate on the stage, just making sure one of the vineyard ladies upstairs doesn’t spot you)
The Paparazzo (you can isolate him in the room where Saint Claire and her spy girl start their conversation by putting down a briefcase. Of course you’ll have to have triggered that conversation beforehand and also distract the security guy who patrols in and out at the opportune time with a dropped weapon)
The Collector (lots of waiting, when he changes his clothes. Getting out of that room is then the biggest challenge)
The Gunrunner (you can lure him behind the big army vehicle)
Others I haven’t tried yet
