Please be as specific as possible when letting us know what is missing or incorrect. For example, say "this game's trophy difficulty should be 8/10", with a link to a website corroborating this difficulty estimate (if possible), not "this game's trophy difficulty is wrong".
Resident Evil 3: Raccoon City - Demo does not have any trophies. This is because it is a demo and/or soundtrack, neither of which typically get trophy lists. The full (i.e., paid) version of the game likely has a trophy list.
Experience a taste of this stunning re-imagining of Resident Evil 3.
Play a section of the opening of the game, specially tuned for this demo, and get a glimpse of the tragedy that befalls Raccoon City.
