This first Abstergo intermission scene is very straightforward. First up, respond to Melanie by looking up first, then look down to calibrate your sensory areas. After that , follow herinto down to the lobby take your new tablet.
Keep following her again and ride the elevator, then go to the Subject 17 floor. After the meet-up with your boss, you can go ahead to your workstation and log-in to the Animus system to continue with the story. There are computers that you can hack and Sticky Notes that you can collect in this "real world" part of the game. You'll be introduced to hacking later on. Don't worry about the sticky notes and computers at this point; all of them can be collected even if you finish the game. These collectibles don't count towards the 100% synchronization of Edward Kenway's memory sequences.
