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".
Masquerade: The Baubles of Doom - 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.
Playable on: PS4 only Masquerade is an action-adventure set in the fantasy world of The Realm, centered around a battle for the mythical Druid Orbs, the most powerful pair of balls in all the land. For it was said that whomever possessed the Orbs, possessed the power to rule all. From foreign shores came the Clowns, an army of morose maniacs determined to find the Orbs. And so began the Great Clown Invasion.
