From the introduction: Catbox is a GM-less tabletop game meant to evoke crime-thriller movies about people with differing agendas all stuck in the same place (Reservoir Dogs, The Hateful Eight, Hotel Artemis, Bad Times at the El Royale). Each player will play a character with a secret agenda to complete, one that may or may not place them in direct opposition to the other characters and NPCs they are trapped with.
