First and main thing:
You have to own NVIDIA graphics card that supports Ansel for this to work.
If you have graphics card of other vendor or your card does not support Ansel, this guide will not work for you
Find, download and install any HEX editor.
In this guide I will show how to unlock Ansel in Hex Editor Neo, but you may use any editor you want.
After installing HEX editor open it.
In the main window find the Open button
Push that Open button and window will appear.
In that window follow the path to where your game is installed.
Highlithed part of the path in the pic will be different for you, but all the rest will be the same if you use DX12:
If you use DX11 the path will be:
but you know, I recommend to edit both files, no harm will be done
Find HITMAN2.exe file and click OK (or Open) as shown on a pic above
This file will be opened and you will see a lot of numbers there
In the upper menu of the program click Edit and there find an option Find…
Or just apply a key combination Ctrl+F
A window will open
In this window firstly select Hex in highlithed drop-down list
Manually type 83 F8 0F 75 1C 0F 54 as shown on a pic
After you click Find button it should jump you to needed area
Should be highlighed with green the first digit - 83.
Further in this row find 75 and click once on it, it should be highlighted now as shown on a pic above.
Replace this highlighted number with EB by just typing on your keyboard
It may type in a lower case, don’t worry, it will still work
After replacing is done, save the file
After clicking Save button the window will appear
Confirm saving by clicking Yes
That’s all. Hex editor can be closed.
If you did everything correctly from now on you can use Ansel in free camera mode and fly over all the map wherever you want
You may need to do all this again to unlock Ansel again after each game update.
Hope I described everything more than clear, so no questions should left.
But if you still have any questions, feel free to post them here.
