HITMAN

To reach Sapienza Mastery level 20 you need to complete many of the 91 challenges to gain XP. I reached level 20 when I had completed around 45-50 of the 91 challenges, so you don't need to complete them all. The challenges can be seen in the main menu and pause menu, they include tasks such as:

Starting in different locations.
Equipping different disguises.
Finding different items.
Completing different assassinations.
Escaping from different exits.

When you complete certain challenges, it will appear in the top right corner as successful. You then need to finish the mission for them to save and for your level to update. You can reload saves to retry if you miss certain opportunities and challenges can still be accomplished.

I have uploaded several walkthrough videos which will mainly be different assassinations which get you around 5000xp each, but include me starting in different locations, finding items, changing disguises and leaving through different exits.

Weeding The Garden Assassination

Silence Of The Man Assassination

Error Plane Assassination

A Poisonous Vintage Assassination

Getting Your Hands Dirty Assassination

Plague-iarism Assassination

Eye For An Eye Assassination & Investigator Challenge

Mastery Level 20
You need to complete between 40-50 challenges to gain enough XP for Mastery Level 20. I've created a number of guides for Sapienza to help you on your way and consolidated them below.

Sapienza Walkthrough
This is a walkthrough of the Sapienza mission, the second downloadable episode of Hitman.

Some of the challenges don't show during the video because I have already reached max rank by this point and completed most of them. You might find you complete a few additional challenges I haven't noted.

I cover off the following challenges with some reasonable XP gains during this playthrough:

- Absolution challenge | Get inside the morgue. Do not get spotted.
- Getting Access challenge | Get a keycard for the mansion lab.
- No Evidence challenge | Complete World of Tomorrow with no bodies found. If you are detected by cameras, delete the security tapes.
- Eliminating the Competition challenge | Destroy the virus.
- A Family Affair challenge | Find Silvio Caruso's family video.
- Palgue-arism challenge | Assassinate Silvio Caruso with an amputation knife while disguised as the plague doctor.
- Hold My Hair challenge | Assassinate a target by drowning them.
- Love Triangle challenge | Hide Francesca De Santis and the golf coach in the same closet.


The Sapienza Trinity
There are three unique ways that you need to kill Silvio Caruso for the The Sapienza Trinity achievement and complete challenges along the way.

1. Down his plane with a cannon (Error Plane Challenge).
2. During Therapy.
3. Shoot him through the telescope.

This will require three separate playthrough's.

Error Plane Challenge
Starting equipment:
- The lockpick is all that's required, everything else is optional.


Therapy Kill
Starting equipment:
- The lockpick is all that's required, everything else is optional.


Telescope Kill
Starting equipment:
- A Sniper Rifle and access to the ICA safehouse is all that's required, everything else is optional.


Summer Bonus Episodes
The summer bonus episodes also count towards Mastery Level 20, so try these too.
