After the scene, the mission is far from over. You now have to escape the Royal Hotel. Enemies are crawling all over the place so do your best in maintaining stealth and avoid drawing attention to yourself as you stalk them and thin out their numbers. You can pick up the Harmann AT-40 Tony used but it only has one ammo. Leave the office and kill the first set of guards. Make your way to the elevator until you reach the lobby.
There are a lot of Derazio’s men there waiting. You can use grenades to thin out their numbers but you also have to be careful of the enemies flanking around you, especially those shotgun-wielding mobsters. After killing most of them, you can leave through the front door. Escape the police blue zone or use your Police Dispatcher associate. Leave the green area to complete the take over to this district and trigger a sitdown.
