Hack 'n' Slash, developed by Double Fine Productions, is a top-down action game that combines hacking and slashing gameplay. The game is set in a village where the head wizard has mandated strict laws for everyone's safety. Alice, the protagonist, decides to unravel the mystery behind these laws by hacking into the game's world using her USB sword.

The gameplay is unique as players can use the sword to interact with any in-game object that has a USB port. The players can also alter the behavior of their enemies by hacking them. The Third Eye Hat, an homage to internet slang, allows players to access a debugging console that was used by Double Fine themselves. This console allows players to peek into the containers, examine the code, and even adjust the in-game clock to affect the flow of time. The game also has a character progression system where players can find books to hack more in-game objects.
