Instructions
Enter the Crimson Caravan compound after 11:00 p.m.
Walk to the main building and crouch to avoid detection.
Enter the main building and locate Alice, who will either be sitting at her computer or sleeping in a cot nearby. Make sure there are no other individuals in the room before continuing. There shouldn't be anyone other than Alice in the building if you enter after 11:00 p.m.
Dispatch Alice in the manner that makes the most sense based on your character's strengths. It is important that it's done quickly, otherwise she may flee outside and alert other people who will attack you.
