Catherine is a cross-genre video game in which players control Vincent Brooks, a man who is tormented by deadly nightmares after becoming involved with multiple women. The gameplay is divided into two parts; daytime social simulation segments where Vincent interacts with various characters at the Stray Sheep bar, and nightmare segments where he navigates deadly block towers using a combination of platforming and puzzle solving.[4][5] The game is split into three modes; the single-player story campaign dubbed "Golden Playhouse", and "Babel". Multiplayer-exclusive "Colosseum" challenge levels are unlocked after first completing the story.[5][6]
