Start the game with the -developerkeys command line parameter. Start the game, then press [Page Up] or [Page Down] to cycle character models until reaching one of Mona Sax as she appeared when in the shower.

Even though the weapon menu does not show them, you will still select it. Do not go past the second sink; if you do the scene will change. Stand by the bathroom entrance and throw a few grenades. You will see the Mona’s body fly out of the shower. Because of the rag doll physics used in the game, you can move Mona all the way to the entrance with some well placed grenades. Note: This may require a few attempts.
Start the game with the -developerkeys -screenshot command line parameters. Load Part 1 Chapter 6. As soon as you start, press [F3]. Use the cursor keys to navigate the camera through the funhouse, just as if you were walking Max through. You will need to go through the cages, etc. When you get to the part with the locked door that goes into Mona’s apartment, walk through it. Go through the locked bathroom door also, and straight into the shower. You can now see Mona fully naked taking a shower. She will wash her hair repeatedly and writhe her body. Press [F10] save a screenshot in the “screenshots” folder in the game directory.
Changing skins, locations, and the flow of time:
Enable the coder code. Press [Page Up] or [Page Down] to change skins. Press [Insert] or [Delete] to scroll through set locations in the level. Press [Home] to speed up time or [End] to slow it down.
