It's a game script for 3Dsmax (2009 or higher version). Try to catch the red flying saucer. :)
1) Open the max file.
2) Open the maxscript. (drag the script into the viewport, or "MAXScript-Open script...")
3) Have fun!
Please do NOT manipulate the max file, because it could cause problems with the script! If you do any changes in the max file (accidentally or advisedly), please download the ".rar" file again, and reload the max file.
If something goes wrong, or you got an error message, or the 3dsmax brake down, please send me an email, what was the problem.
