The Heart is an item that has appeared in three games in the Rusty Lake series. It appears to be the heart of a human being, though is only rarely found inside a person.
Cube Escape: Case 23Edit
In the Chapel, there is a column of slots on the wall. One of the upper slots holds a fetus in a jar, and the player must pour ink into the jar. The ink coats the entire jar, then disappears to reveal that the fetus has changed into a heart. Now, the heart can be placed into the heart-shaped slot in the lower column, which holds a pair of scissors inside.
Cube Escape: TheatreEdit
During the first play, "The Lady of the Lake", the starring actress will want you to balance the substance of her past lives. In the bathroom, there is a heart inside vanity cabinet. When balanced correctly on the scale along with the other items, the woman will shine a beam of light from her mouth and give the player a flower, ending the play.
Rusty Lake: RootsEdit
In 1865, James has moved into the house of his deceased uncle William. When the clock in the house is set to the correct time, it will open, and William's corpse is found stuffed inside. When interacted with, it falls to the ground. The player can travel into the body through the nipple, and take his heart. This is placed into a jar, becoming the first sacrifice. Finally in 1935, in the underground laboratory, there is a locked cabinet which can only be opened when the other sacrifices are balanced equally on the scales. The cabinet opens to reveal the heart, and when it is placed on the last scale, the tree's roots descend and absorb the sacrifices.
Rusty Lake ParadiseEdit
During the Sixth Plague, Gerard has fallen ill and requires aid. The player pops his boils to clear his chest, then uses a knife to remove his heart. Giving him medicine and aligning his teeth reveals the time to set on a grandfather clock. This opens the dial on the clock. The clockwork inside is taken out, and given to Gerard to revive him. Placing the heart in the clock opens the case below, in which there is a box holding a black cube.
Cube Escape: ParadoxEdit
There is a covered cage, where a Hand appears from inside. When it is given a knife, it goes behind the cloth and reappears with a heart. The heart is placed inside a jar with other organs, allowing the player to take back their brain which has become their present mind.
