Sacra Terra: Angelic Night is an adventure hidden object game developed and published by Alawar Entertainment. The game kicks off with a scene wherein the main character wakes up in a mental institution. The player assumes the role of this character, who also does have any recollection of the events that led to the asylum. Soon after, the protagonist realizes that s/he is in danger because of an evil ritual that went awry. As it turns out, the ritual caused the seven deadly sins to break loose in the town of Sacra Terra. Unless the protagonist sends them back to where they came from, these demons will not only ruin him but the entire world as well.
Gameplay involves numerous hidden object challenges, which take place in the many creepy rooms of the asylum. The player must be keen enough to pick up clues like newspaper articles and tiny notes that will give him/her an idea of what really happened in Sacra Terra. In addition, a shadowy angel also pops up every now and then to drop hints. Every time the player collects a clue from exploring the rooms, it is listed down on his/her journal. In the Easy Mode, tiny light sparks appear occasionally to guide the player to areas or objects of interest.
