Put ALL files into your Max Payne 2 install folder.
Make sure to have set developer mode on.
Right click on the MaxPayne2 shortcut on your desktop and add: -developer -developerkeys -screenshot after maxpayne2.exe"
(Eg, "D:SpilRockstarGamesMax Payne 2MaxPayne2.exe" -developer -developerkeys -screenshot )
This has to be done so you can select alternate skins for some characters by pressing the PG UP og PG DOWN buttons.
I ran into limits of the mp2 engine that stopped me from making the alternate skins selectable from menu.
Start Max payne 2 and select Kung Fu Evolution from the drop down box.
