Question: Where is the headquarters located for the company that had Mud Duck Productions as a subsidiary?
Context: Malice is a platform game for the Xbox and PlayStation 2 developed by Argonaut Games and published by Mud Duck Productions in North America and Evolved Games in Europe.  The Xbox version is not compatible with Xbox 360.  The game was originally supposed to be a title for the Sony PlayStation.  However it was ported and management aimed to release it in late 2001 as an Xbox launch title with band members from No Doubt doing various voice-overs and singer Gwen Stefani doing the voice for Malice.  After a lengthy delay, cancellation, a change in publishers and an eventual revival, the game was finally released in 2004 and was met with mediocre reviews.  This was also the last game Argonaut ever made, due to the company going out of business two months after the Xbox version came out in Europe.
