The second escalation is here. Good thing IO reduced the levels to three, otherwise this one would be even more repetitive than it already is.
Retrieve the fish
Pacify Finley Henry with the fish
Start with restricted loadout (only a Silenced Pistol)
Keep the outfit you were wearing on mission start (Tuxedo with mask)
- Pacify 5 civilians with the fish
Pacify 10 civilians with the fish
Don’t drop the fish
Don’t drop the fish.
Honestly there isn’t much else to say. Subduing 10 civilians isn’t that hard. If you pacify Henry, the three other chefs in the kitchen and the two waiters in the room with the stairs leading downstairs you already have 6 out of 10. For the remaining four you just have to lure some of the people in the courtyard in the smaller rooms. If you don’t know how to lure NPCs to an isolate area, I recommend that you stop playing this game.
