Memento Mori

When I was watching a video game run through on Youtube for a game called until dawn. One of the titles of the game chapters was Memento Mori. Until Dawn is an interactive drama survival horror adventure game. Until Dawn is designed to be played multiple times, as players cannot see all content with a single playthrough. Each playthrough will last about seven to nine hours in length, and the game mechanics utilize an in-game system called the "Butterfly Effect", in which any choice of action by the player may cause unforeseen consequences later on. Later in that week, I had asked what memento mori meant, and it meant remember to die.
