Ever since I first created my 3D illustrations of the haunted mansions, people have been asking me to create an entire 3D walk-though animation of the attraction. It has been outside of my level of expertise and time allowances. However, a Counterstrike map-hacker who calls himself "Nipper", has created an amazing 3D recreation of the Liberty Square Haunted Mansion as a Counterstrike level! His level of detail is eye-popping and he even included the sound effects and Ghost Host narration.
Check out the video walk-through.
