The AMS is an American government agency responsible for criminal investigations and intelligence collection worldwide. It serves as the main heroic faction in the House of the Dead series.

Since the 1998 Curien Mansion Incident, the agency has handled numerous cases involving outbreaks of biologically-engineered creatures. By 2019, following the worldwide collapse of human civilization, the AMS disbanded; former agent Thomas Rogan, alongside partner Dan Taylor, formed an independent group to combat the undead threat.

History Edit

While the AMS' true purpose is never stated, it appears to be outside of other US Government organizations and/or jurisdiction. For example, when G confronts Papa Caesar he specifically places Caesar under "AMS arrest", though it is left ambiguous whether G actually has this vested authority or if this is a simple threat.

The Zombie Revenge instruction manual claims that the AMS is an American agency, this was later verified in Overkill, revealing that it was active during the 1950s being involved in the secrecy of the experimental "Formula X" that was originally intended to be used in "OPERATION OVERKILL".
