_Robert D. Anderson & the Legacy of Cthulhu_ is a fan made project based upon
the _Arkham Cycle_ Cthulhu stories by H.P. Lovecraft. More specifically, it is
an adaptation of the pen & paper scenario _Himmlers Schoggothe_ by Samuel
Miller. The game is best described as a horror novel, using three means of
storytelling: spoken word, filmed cut-scenes and playable content from a
first-person perspective, built with the FPS Creator engine.

The player is cast as the hard-boiled private investigator Robert D. Anderson
from New York. That is just a pseudonym however to hide his real name, Robert
Dietrich. After an incident, he is forced to investigate his origins and
travel to The Third Reich where the castle of his ancestors is occupied by SS
troops and members of the Order of the Black Sun.

The game is divided into 15 chapters. In the playable sections players must
explore the castle, talk to characters, solve puzzles and defeat enemies –
combining shooter with adventure gameplay. Up to 20 weapons and spells can be
collected, but it is encouraged to avoid confrontations.
