The store "Jill's Sandwiches" is a reference to the scene in the original Playstation Resident Evil when Jill narrowly avoids being crushed by a trap and Barry says "That was too close, you were almost a Jill Sandwich!" There is a Prestige Points sticker on the sign, so taking a picture of it raises your PP count.
Due to the fact that this game takes place almost entirely in a shopping mall, there is a warning on the front box cover of the game that states: This game was not developed, approved or licensed by the owners or creators of George A. Romero's Zombie : Le Crépuscule des morts-vivants (1978).
The restaurants "Chris' Fine Foods" and "Jill's Sandwiches" are direct homages to the characters of another of Capcom's Horror series: Resident Evil.
In-game there are various references to the Mega-man series. Frank can wear a full Mega-man outfit and can unlock the 'Mega-blaster'. Also, there is a Mega-man film being advertised outside the movie theatre.
Briefly thought to have been banned in Germany, but was simply refused to be rated. The game still saw release, just unrated.
