You’re back in the Abstergo office. Stretch your legs while taking the elevator up to the 15th floor. You have a brief meeting up there, and you get Level Two Security access to the building. That unlocks the doors that have a “2” on them, so there are more Tablet Documents and computers available at this time.
Also, there’s a server to repair on this floor (it’s a piece of cake). Attend that before going back down to your cubicle.
There is a security door on the eastern side of the second floor. Get both computers over there, if you wish. Return to your main cubicle to unlock “A Worthy Cause” and to start another broken fragment of memories.
