To successfully complete the “House Built on Sand” escalation in Hitman 2 with a Silent Assassin rating, you must adhere to strict guidelines and utilize precise strategies throughout your mission. Below is a comprehensive guide detailing the objectives and strategies you need to follow:

Main Objectives & Conditions for Silent Assassin

1. Disguise Requirements:
– Start and Remain in the Raven Suit: This is crucial; changing disguises at any point will lead to mission failure. The raven suit is essential for remaining inconspicuous.

2. Retrieve the Sieger 300 Ghost Sniper Rifle:
– Early in the mission, locate and obtain the Sieger 300 Ghost, a silenced sniper rifle. This weapon is vital for executing silent long-range kills on two of your targets.

3. Target Eliminations:
– You must eliminate the following targets:
– Sara Zitouna and Nour Joumarni: These kills must be executed using the Sieger 300 Ghost sniper rifle while remaining in the raven suit.
– Aitor Ibirika, Arey Seoane, Damien Abergel, Dubaku Dufort, and Hamza Diwan: You can eliminate these targets using any silent method, but you must still be dressed in the raven suit, and, importantly, these kills must be conducted without raising an alarm.

4. Avoiding Detection:
– No Witnesses: If anyone observes you committing an illegal action, the mission will fail immediately. This includes kills or any suspicious behavior.
– No Agency Pickups: Agency pickups are off-limits during this escalation. Plan your inventory and strategy accordingly.

General Silent Assassin Strategy Tips

– Utilize Cover: Always use environmental cover and maintain proper line of sight when taking shots with the sniper rifle to ensure you are not detected.
– Body Disposal: After a kill, if possible, ensure the body is hidden or disposed of to avoid being discovered by guards or others.
– Avoid Security Cameras: Steer clear of areas monitored by cameras. If you must cross such areas, consider disabling the cameras without drawing attention.
– Create Diversions: Use distractions like coins or non-lethal environmental actions to lure guards away from key areas, providing openings for your actions.
– Patience is Key: Stealth requires time. Rushing can lead to mistakes that expose you to enemies.
– Timing Your Shots: Take advantage of your targets’ movement patterns; wait until they are isolated and best positioned for a clean shot.
