So, last night, I accomplished at last a playthrough of this map that I’d been tinkering with all year, and it worked. Following my usual style of SASO, in a gloved suit, bringing my fiber wire, Silverballer, concealable knife, and the emetic pen syringe in the hidden stash in the restroom, I managed to complete the mission with only 3 knockouts, and they were achieved through two bananas and a water puddle, so in-story, nobody knows a person was responsible, and in hindsight, the water puddle was unnecessary.
Using just keycards and without disability cameras, I snuck my way to the penthouse, cut the parachutes with my concealable knife, then activated the meeting between the targets. Once they were in place, I triggered Grey’s speech to them, then hid in a container when the time came for him to ask me to kill them. They left the area, but because I’d used the emetic pen and a banana peel on the helicopter pilot they couldn’t escape, so they used the parachutes and died.
I got out without anyone knowing that it was all nothing more than a series of clumsy accidents, able to trigger the meeting with Grey, which I’m pretty sure is meant as a canon event, while killing the targets with the parachute failure, which I think is the most appropriate end for them, and all without having to disable security, use a disguise, or subdue anyone in a non-accidental way, and without compromising my usual loadout of fiber wire and Silverballer.
I had been hoping since my first playthrough, when I learned what happens if you don’t kill them at the meeting, that I could pull this off, and I did it perfectly.
