The Infernal Masquerade is a gothic horror PS2 -inspired take on the classic minesweeper game, along with additional hints on the hidden undead, that make it more up to the player's skill to find the vampires behind the venetian masks. The adventure starts in 1868, aboard a ship sailing towards London, as a vampire hunter searching for the undead menace hidden among the masqued partygoers traveling. Armed with roses, infused with the sunlight that made them grow, you mark the suspected vampires by placing the roses on their chests and finally release their energy to scorch the bloodsuckers to smoldering husks. You will be helped by the humans among the vampires, whom are too afraid to all but hint whom in their surroundings is a vampire. You will move from different locations to clear often several groups of people from the infected.
