HITMAN 3

This will take two playthroughs as you can combine shooting Alex from the roof and putting her to rest. You will need to unlock and bring a sniper with you through level mastery or by carrying progress over from Hitman 1 and Hitman 2. First, head to the graveyard and use your hitman vision to find and shoot the 3 bird nests in the area. Then make your way through the house to the roof above Alexa's office. Wait for Alexa to walk through the graveyard and then stand in front of her grave before taking the shot with the sniper rifle. Second, you will need to start in the Staff Room with a lockpick. Rush upstairs into the bedroom with the cane and then head up to Alexa's office. Instead of going inside, walk to the end of the hall to find a secret switch that you can use with the cane to access Alexa's secret room. Then simply kill her, if you are too slow and she has left the room you will need to restart.
