Knack is an action-packed beat 'em up platformer developed by Sony Interactive Entertainment for the Play Station 4. It was released alongside the PS4 console and was even bundled in some regions. The game features Knack, the self-titled protagonist who can disintegrate into little pieces called Relics and absorb various materials to be its parts. This enables Knack to turn into ice, iron, and crystal Knack, getting bigger and smaller depending on the number of materials within him.

The game is set in a high-end world populated with advanced humans who have discovered the powers of Relics to compose Knack-like creatures and goblins who are presented as a lower race continually trying to start a war or rob humans. Gameplay involves dodging, jumping, punching, and kicking enemies in various fashions, making it a thrilling experience for action game lovers.
